After having many failures with the original 4.12 60A VESC due to FOC caused DRV errors (I'm sure many can relate), I stumbled across this controller about 2 years ago. The price was hefty in comparison, but the performance it promised was unparalleled. Unfortunately, the claimed 200 amp of continuous current is very optimistic. I purchased a bluetooth module which allows me to connect the VESC to my phone, program, and monitor it. I found that its' readings are extremely accurate. I built an electric bike with a mid-drive motor setup, 50v Lipo graphene packs, and this controller. I did some testing with the setup, and found that on a day with about 70*F ambient temps, I could only pull about 100-120 amps continuous. Granted, this is much better than the previous controllers I have used, but it is not anywhere near the claimed 200 amps. When I tried to put this much current through the controller (full 200A), the motor would simply stall. I believe it is a limitation of the motor simply being overloaded and not the controllers' doing, but I thought I would mention it. I could only realistically output 180 amps; enough to get me to 30mph from a standstill in under 3 seconds! Bonkers fast for a deathtrap Ebike. But after about 10-15 seconds at this current, the temperature cutoff would quickly reduce my current to below 100 amps, and oscillate a few times before coming to a rest at 110 amps or so. I decided to take it upon myself to fix this overheating issue by removing the stock thermal pad which was on the backside of the MOSFETs, and thermal glued 6 individual copper pads (as if I did one slab, it would risk shorting the MOSFET's N-channels!). After this, I installed a new thermal pad, and also put huge heatsinks on the backside of the controller. These two mods allowed me to now pull upwards of 160 amps continuously; about 7-8 kilowatts! That's more like it. So unfortunately, if your build STRICTLY requires a continuous 200 amps, this controller (while otherwise quite a good buy) will not do it. Stock, I would guess 200 amps would only last for 8-12 seconds. The only other "gripe" I have with the controller is the micro USB port. After using that multiple times for programming with my computer, it BROKE off! I was stranded... until I bought the bluetooth module. Luckily, the Baud rate and firmware version that remained "bricked into" the controller talked to the new bluetooth module correctly. I was able to program it from then on with my phone (which I may say is a FANTASTIC buy, even though it is about $40-$50USD).
All in all, I do recommend this product. Just don't expect the level of performance it suggests, and be careful with the USB port! If you want to see it in action, check out my YouTube channel: Marcus Herold . I have 2 videos up as of now which are "Ebike vlogs" on my bike using this controller. "Riding with Nate!" is a much more comprehensive review because you can see much more details in the programming. I plan on uploading a video in the near future of the heatsink mods I made to it. Good luck with your projects!
Maytech 200A VESC6-based Speed Controller for Electric Skateboard Mountainbaord E-bike/E-scooter Powerful MTSVESC6.6 Lawnmower Robot/ Camera motorized dolly
|Cont Current||200A||Splash Waterproof||Yes|
|Hardware||Based on VESC6.0||Firmware Updatable||Yes|
- When you receive the VESC, please test without load and do not connect motor, first check if the VESC can successfully connect to your computer, if ok, then connect to motor and you can start to adjust parameters.
- Do not use switching power supply, the instant voltage when switching power supply connect to VESC is very high, which would easy damage the VESC.
- Do not push the throttle too hard when test without load, gently and slowly speed up.
- Be cautious when adjust parameters, if parameters set mistake, would also easy damage the VESC.
- Please must remember to change to corresponding modes when you adjust parameters, for example, the VESC default mode is BLDC mode, but if you want to detect FOC mode and adjusted FOC parameters, at this time if mode in VESC_TOOL didn't change to FOC mode, then when you push throttle, would easy burn the VESC, same as FOC mode.
In FOC mode, ERPM suggest to control in 30000-40000; In BLDC moed, ERPM suggest to control in 50000-60000, otherwise driver IC would easy to be damaged. ERPM= motor pole pairs number * KV * Voltage
ERPM= motor pole pairs number * KV * Voltage
- If you use UART port, the wire better do not over 0.5m or even shorter, and better use Stranded wire.
- For V4 based VESC:
Do not suggest to use FOC mode, suggest to use BLDC mode.
If need to use FOC mode, then must use voltage under 20V.
- The above 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
