CCS/BOOSTXL-DRV8301: Motor burned when doing lab5c !

Part Number: BOOSTXL-DRV8301
Other Parts Discussed in Thread: DRV8301

Tool/software: Code Composer Studio

Dear TI team, 

I am working with DRV8301-69M kit , want to control a small low inductance BLDC motor, got the motor parameters from lab2c , moved them to user.h of lab5c and ran the code . 

the motor smoked when starting to identify the inertia !!!!! what could cause this ? I didnt change the goal speed , but could this burn the motor ?! 

Regards,

    Please make sure the correct motor parameters are identified by using lab02c and try to run lab05a or lab05 first to validate the motor parameters. And it's very important that you need to set the maximum current (USER_MOTOR_MAX_CURRENT) and overcurrent protection for the kit by configuring the DRV8301 registers according to the spec. of your motor.

    BTW, InstaSPIN-motion is not recommended for low inductance as well. Especially, sensorless InstaSPIN-motion. If you want to do this, please take a look at the lab guide, you need to set the goal and stop speed based on the motor accordingly.
