Hi guys, I ordered this hub motor from china: https://de.aliexpress.com/store/product/Maytech-Free-Shipping-1pcs-truck-for-single-motor-and-1pcs-70mm-hub-motor-for-electric-longboard/1630416_32820824995.html?spm=a2g0x.12010612.8148356.60.331d43056Wvysp
I attached to the vesc and set the parameters, but the motor has almost no torque at startup. I can hold it with 2 fingers in place. When I push the board a little it’s enough to keep board rolling but thats it, topspeed is like 10km/h
I resoldered the bullet connectors and tested the connection between the phases (shorted, as it should be)
My best guess is a faulty motor or something off with my settings. I took of the sensor to elimate a fault source and did the motor detection. Changing the Current to 1A lets the motor spin. But the result seems off to me, esp the BEMF Coupling is very high. The tool actually caps it at 900.
The Vesc works fine, I tested it with a different motor. I also tried FOC with sensors mode. That stops the sputtering and gives it more torque. But the top speed is less then impressive.
Can it be that the hub motor has so little torque? Can I fix something about my settings?
