Compare to Original 75_300 VESC, what upgraded points and advantages MTSVESC7.5H have? 

  1. With CNC aluminum alloy heat dissipation case, optional water cooling system and forced air cooling system.
  2. With larger heat sink case that has better heat dissipation performance. 
  3. Its heat sink case bottom is coverd by fins that can better heat dissipation. 
  4. Its PCB board has 4pcs MOS paralleled, could withstand higher current, original version only has 3pcs MOS. 
  5. Its PCB board with cooper stripe, can reduce resistance in high current, better heat dissipation. 
  6. With larger capacitor, 9pcs 100V 470μf capacitor, while original version only has 6pcs 80V 470μf. 
  7. With separate design of strong and weak current circuit board, and between 2 boards added heat sink for better heat dissipation. 
  8. Exclusive 5V and 12V external power supply interfaces will not cause interference when powering analog circuits such as twist/thumb throttles.

 

Some Using Tips for this VESC: 

1. If you will use the VESC for water sports or other application that will need to use water cooling, then better choose type with water cooling tube, and work with water pump for cooling. Blow has compatible water pump setup recommended, if you need, can order together. 

2.Must do a good job of heat dissipation! If place it in a sealed container(recommend touse metal container), it must be forced to be cooled with water. Also make sure your container has enough space for the VESC, make sure the cooling tube do not bent, otherwise will influence water flow in cooling tube, also make sure water flow is enough for cooling before office use.

3. Before the new ESC is officially used, please test it with a low-voltage and low-throttle, after success, then slowly increase voltage and throttle. Be sure to pay attention to safety during this period!

4. Recommend to add an electronic switch with short circuit protection function between the ESC and battery, such as MTS2009AS 300A electronic switch or BMS with switch function. It is not recommended to use only contactor without short circuit protection!

5. The battery and motor side terminals must be connected tightly, they can’t be loose. Also please make sure terminals not touch case or other wires, here's the video shows you the way to install cold-pressed terminal connector: https://youtu.be/unFfV9RPPCc

6. In actual use, please use hot melt glue to fix the hall/UART interface cables the corresponding sockets of the ESC, to prevent the cables loose due to the bumps of the vehicle!

7. Please do not disconnect relay switch or electronic switch during usage ! Otherwise it will cause electromagnetic interference, which might damage the VESC. 

8. If you use the VESC to work with our MTSKR1905WF remote on Esurf/ Efoil, please noted below settings: 

Our remote PWM signal output pulselength in Esurf mode is 1-2ms, no brake no stop, and in VESC default pulselength is 1ms start, 2ms end, 1.5ms center, so if you will use our remote in Esurf mode, then please adjust below settings in VESC_TOOL: 

PPM Control Type: Current no reverse
PPM Mapping: Pulselength Start: 1.1ms; Pulselength End: 1.9ms; Pulselength Center: 1.5ms

9. In PPM Control type, do not use Duty Cycle or Duty Cycle No Reverse, this control type only works at fighting robots, 3F Prototyping, drone application, because this control type can't fully disconnect battery power, it needs battery to absorb braking energy. 

The above tips are only suggestions based on the experience of our engineers. how to actually operate is up to you.  Parameters for different setup is also different, please noted
