Hello, I am part of a student racecar building team called Armature Racing (http://www.armatureracing.com/
, and we are using the Nissan Leaf 2012 inverter, motor, and battery in conjunction with Damien Maguire's code (https://github.com/damienmaguire/Nissan ... Controller
) for the Arduino Due to control to inverter. Today, we have tested sending torque commands to the motor. The torque commands were successfully sent, but did not spin the motor at all, and a speed of 0 RPM was reported by the CAN messages. Furthermore, a high pitched squealing sound started emitting from the motor, indicating that the motor is stalling. When applying higher speeds, this squealing sound only became louder.
We have the Nissan Leaf gearbox (set 7:1) mounted on the motor, and I believe that the static friction from this gearbox is what is causing the motor to stall. Force is being applied but there is no rotation of the axle to be found. The torques we tested the motor for were between 0 and 400 (on a scale from -2048 to 2048, seeing as the inverter requests a 12 bit torque). At 400, the squealing became loud enough to where we felt concerned and immediately stopped.
Does anybody have any advice or information regarding these issues? It would be much appreciated.
