I am a part of a college club which builds EVs, we have a 3kw bldc motor which says 48V/60V and with a rated torque of 9.6Nm. And peak can go upto 40Nm. So My car is around 250Kgs and I have a 60V Li-ion battery and a motor controller that the vendor gave with the motor. Initially it was good but this one time during driving the brakes got jammed and the controller started overheating and ever since the performance has decreased significantly and the controller heats up a lot. I was planning on buying a kelly programmable motor controller. I need some help and guidance.
3kw motor for an EV controller? I used a Vevor 3kw for my outboard conversion and that pushed me up to 5 knots (9km/h). A car is needs a WAY stronger motor… What are you converting?
Look at the Vevor 3000w motor - is it the same re branded? If so, I can tell you it seems to do peak 3000w for a few seconds but I can’t get more than 1600w out of it. And the Vevor 3000w motor was incorrectly designed since they removed the fan because they couldn’t fit one in. It’s pure shit. I hope that’s not the same you got.
Aah well the competition I’m attending has a motor power limit of 3kw. The motor was manufactured by Mechatronics motors vendor from India.
