Usually after connected motor, VESC to your computer and VESCTOOL, you can just run configuration with Wizard--Setup Motors FOC, choose correct motor type (For example, for Maytech 5055, 5065, 6355, 6365, 6374, 6396, 8085 choose Medium Outrunner, for Maytech Inrunner motors MTI65162, MTI85165, MTI120116 should choose Larger Inrunner type), and enter correct battery cells information and it will detect automatically, and after detect successful, some value need to be adjusted manually, which is the Motor Current Max Brake and Battery Current Max Regen.
This 2 Current values are important, you need to consider your battery charge current.
Because flow of braking current is from motor through VESC controller to battery, VESC will adjust current send to battery according to the Motor Current Max Brake and Battery Current Max Regen (battery charge current) values you write.
If the values you set too high and beyond charge current your battery could handle, your battery would unable to absorb excess reverse/braking current, then it will send the excess current back to VESC. But if the excess current exceeds the max current that the VESC could withstand, then would cause the VESC heat and even worse burn the VESC, also may damage your battery or affect battery lifespan.
So how to set these 2 revese current values?
Traditional technique is fill up with very thick waterproof glue, while Maytech motor has thinner painting for waterproof and anti-rust over the stator and rotor, because thinner painting has better heat dissipation performance, while thick glue would influence the heat dissipation, easier gets heat and hard to reach good efficiency.

To build a electric skateboard, below is the items you will need:
Build your Board:
Step 1: Mount the trucks and motor to your deck with appropriate spacing. recommend first prepping your motors by adding them to your rear truck, inserting them into the appropriate mounts and installing the motor drive pulley. Test both motors and make sure they spin freely with no unwanted drag from the drive pulley.
Add the wheel bearings securely and press them in, repeating for all wheels. Most motor sets come with an instruction/installation manual, so follow it closely. Hub motors are very straightforward to install, with belt drive motors proving more technical. Watch the belt drive installation process here.
Note: ensure that all components are securely screwed in to avoid failure or injury when riding.
Step 2: If necessary, drill holes in the case for cabling, switches, etc. We recommend starting off small, before gradually widening with larger drill bits. Going straight in with the biggest drillbit runs the risk of cracking plastic, which could compromise waterproofing and the overall protection of your components. Make sure to clamp your deck/case down before drilling to keep it in place.
Note: this task varies depending on deck size, battery placement and other factors.
Step 3: First, test the fit of both the battery and ESC within the enclosure. Install the battery and ESC into your case. Connect the charging port to the battery and power switch to the ESC, before finally connecting the battery and ESC.
Note: avoid connecting the battery until all other electronics are either test fitted or in place already.
Step 4: Feed the motor wires through the case and connect them to the ESC. Test everything with the controller beforehand. Once both the battery and ESC are secure, add the receiver for your remote control/transmitter. Most ESCs come with instructions, which we recommend following closely.
Test everything out by turning on the power switch. At this stage, the ESC should turn on and show a green light, meaning that everything is correctly connected. Those who opted for a virtual ESC must now program their controller using a VESC tool. We recommend watching this tutorial for all the fine details on programming a VESC.
Note: make sure your electrical components are off when testing to eliminate the risk of electrocution.
Step 5: Seal the case securely and enjoy your new eBoard. This is done through screws or adhesive, although we recommend both for maximum safety. Ensure there are no pinched wires or poorly secured components. If you bought a kit, please follow the kit instructions closely!
Note: ensure that there are no loose/rattling electrical components before sealing.
Advantage of Maytech MTSPF7.5H 300A VESC:

Agricultural spraying robots can operate autonomously or be remotely controlled by operators, and they can be programmed to follow specific routes using GPS technology. They can also be equipped with tanks that hold the required chemicals and can adjust the flow of chemicals depending on the crop height and density.
One of the major advantages of using agricultural spraying robots is that they can increase efficiency and productivity on the farm while reducing labor costs. Additionally, they can help to minimize exposure to chemical applications by human operators, improving safety and reducing the risk of related health problems.
Overall, agricultural spraying robots are an innovative and practical solution to the challenges facing modern agriculture, and they are likely to be increasingly adopted in the coming years as the farming industry continues to evolve and seek more sustainable practices.
]]>And to build your own DIY foil assist, electronic parts are very important:
Choosing the right motor, controller, and remote for a foil assist board is important. There are many factors to consider, including the size and weight of the board, the desired speed and torque of the motor, and the range and reliability of the remote control. Here are some general guidelines to follow:
Power and Speed: Choose a motor that can provide enough power and speed to suit your needs. The power will depend on the size and weight of the board, as well as the desired speed. A motor with a power rating of at least 500 watts is typically sufficient for most foil assist boards. The speed will depend on the motor’s Kv rating (RPM per Volt), which should be chosen based on the desired top speed.
Controller: The controller should be compatible with the chosen motor and provide enough current to power the motor. It should also have an appropriate voltage range that matches the battery and motor voltage. Choose a controller with a high-efficiency rating for maximum battery life and minimal heat generation.
Remote: The remote control should be reliable and have a decent range for the board’s intended use. It should also be comfortable and easy to use, with intuitive controls for speed and braking. Look for a waterproof remote with a rechargeable battery for convenience.
In summary, choosing the right motor, controller, and remote for a foil assist board requires careful consideration of the board’s size and weight, desired speed and torque, and usage conditions. It may be helpful to consult with an experienced manufacturer or supplier to ensure that you select components that work together well and provide maximum performance and reliability.

]]>Some customers has ordered our motor and opened to see its inside see if it's waterproof or not. But due to Maytech new technique that is different from traditional waterproof technique, that lead some customers misunderstanding, here we apologize for that.
Then what waterproof technique Maytech did on its 6374 waterproof motor?
Before we start producing the 6374 waterproof motor, we did some research, and found that some motors fill up with black waterproof glue that is softer, when motor heats the glue would swell and narrow distance between stator and rotor, stator would easily touch rotor, which will shorten motor lifespan.
Also thick glue fill up with stator and rotor would easy cause heat and affect motor power.
So we decided to find a new solutions and made different versions upgrading, and finally use current version. We use thinner waterproof and anti-rust painting over the stator and rotor so can better dissipate heat.
And Our stator and wirings are all covered with transparent insulating paint, and magnets did anti-oxidation and anti-rust treatment.
And below is customer feedback with our new technique waterproof 6374 motor on Foil assist:
And below picture is Maytech non-waterproof version motor inside look:

The what is the difference from Efoil?
Efoil is flat-water system, it is much heavier and cost is much higher, speed is faster, mainly ride on flat-water.
Foil assit system can be used on different application, to turn your non-electric foil to electric with lower power motor and battery, lighter weight, minimalistic, less cost, but as use smaller motor and battery, speed is less.
You can choose the suitable system you need.

1. What is Arc shaped Magnet ?
Arc shaped magnets are also called tile shaped magnet, curved magnet, their shape curved like tile, is commonly used in brushless motors, generators and torque couplings due to the configuration of their north and south polarities. The shape is cylinder-like, with a slight curve to their body, making them ideal for cylinder-like materials and piping. Neodymium magnets are much stronger than other magnets, using neodymium arc magnet can build stronge forces and power in the items they inhabit, the material Maytech use is Neodymium arc magnet in their C4 & C5 motor.
Neodymium arc magnets are also called Arc segment magnets, which are made by wire cutting of the block magnets. This type of segment magnets are commonly used in DC motors, both for rotors and stators.and other motors.
2. What other shaped magnets are also used in motor?
For brushless motor, commonly used magnet also have rectangular shaped (flat magnet, straight magnet), double arced shape magnets.
The air gap of the arc shaped magnetic steel is uniform, while the rectangular shaped magnet air gap is not uniform, so arc shaped magnet will allow you to get the magnets closer to the ends of the stator (decreasing air gap) and in doing this increase the flux between them.
All other factors being equal (windings, stator, magnets, airgap, flux ring), the motor with curved magnets will be more powerful than the flat magnet motor.
3. Why arc shaped magnet is better?
As above mentioned, with arc shaped magnet could decrease air gap when stick magnet to stator, and increasing flux between them, their shape allows for a unique electrical flow of power continuing to drive their usefulness in motor-like items.
Except for that, with arc shaped magnet, when motor runs at high speed, would produce less airflow vibrations and motor variation, more stable and higher efficiency, better performance on BLDC motor.
There is no doubt that the curved magnets are better suited for these brushless outrunner dc motors. Also the curved magnet motor will produce more torque for a given amperage.
Here are also other arc shaped magnets, the one Maytech used in C4 & C5 motor is curved botth arc type

]]>Brushless dc motor uses electronic controller to switch DC currents to the motor widings producing magnetic fields which effectively rotate in space and which the permanent magnet rotor follows. The controller adjusts the phase and amplitude of the DC current pulses to control the speed and torque of the motor. This control system is an alternative to the mechanical commutator (brushes) used in many conventional electric motors.
What is Brushed DC Motor?
Brushed DC motor is an internally commutated electric motor designed to be run from a direct current power source and utilizing an electric brush for contact.
Brushed dc motor can change speed by change operate voltage or strength of magnetic field. Depending on the connections of the field to the power supply, the speed and torque characteristics of a brushed motor can be althered to provide steady speed and or speed inversely proportional to the mechanical load.
But because friction has effects on motor carbon brushes, they will wear with time goes by, therefore, brushed motor requires some sort of maintainance by brush cleaning or replacement, which would increased cost of maintainance and time.
Also brushed motor has lower speed, although it has high startup torque, but it's unable to maintain high-level speed, this is because it will easily geats heat if running at high speed continously.
So more and more electronic applications start to replace brushed motor with brushless motor.
1. High Efficiency:
Brushless motors can work continuously at maximum rotational force (torque).
2. Controllability.
BLDC motors can be controlled by feedback mechanisms, to provide precise desired torque and rotation speed. Precision control in turn reduces energy consumption and heat generation, and—in cases where motors are battery powered—lengthens the battery life.
3. High durability and low electric noise generation
For brushed motor, the brushes and commutator wear down as a result of continuous moving contact, and also produce sparks where contact is made. Electrical noise, in particular, is the result of the strong sparks that tend to occur at the areas where the brushes pass over the gaps in the commutator. This is why BLDC motors are often considered preferable in applications where it is important to avoid electrical noise.
In conclusion, compare to brushed motor, brushless motor produce low noise, faster speed, high power, high efficiency and low maintainance cost.
Brushless motor also has wide range of application, electric skateboard, electric surfboard, electric bike, electric scooter, electric car, motorcycle, AGV, rc car, rc boat, rc airplane, multicopter, medical devices, computer peripherals (disk drives, printers), hand-held power tools, model aircraft to automobiles, washing machines, swimming pool tranning machine, industrail devices, etc.,

Detection Steps:
1. Connect your VESC to computer and VESCTOOL
2. Setup Motors FOC in wizard, write in correct battery cells number according to battery you use, choose suitable motor type you use, here we use 30V voltage, so we write in 8 cells and choose large inrunner motor, and then run detection.
3. During the detection, motor will turn, if you use outrunner motor, fix the motor to a bracket or something.
After detection finished, if detection no problem, will display a window shows you the result success.
4. Setup Input, this is to setup the throttle type you use, pair your throttle with your VESC and choose the throttle input and control type.
About control type, for water sports, recommend to use "Current No Reverse", this is without brake. For skateboard application, choose "Current No Reverse with Brake".
You can also do this step in App Setting.
5. After choose correct throttle input and control type, some values need to attention and adjust manually.
Motor Settings--General--Current
-Motor Current Max: can use current that was detected automatically in previous step
-Motor Current Max Brake and Battery Current Max Regen:
If you use without brake, this 2 values must set to "0", if you use brake, then set this 2 values less than your battery or BMS acceptable max charging current.
-Absolute Maximum Current: This value should be larger than value Motor Current Max.
-Battery Current Max: Set this value according to your battery discharge current.
Then you can apply your throttle and check realtime data.
