Hello, I'm using an RC car BLDC motor with an EVLSERVO1 evaluation board and can't complete the Motor Profiler process. My application has a large mass on the motor, so I need the mechanical model to get better control loop parameters. I have manually measured the electrical model and have successfully done the following:
- Run the motor open loop in voltage mode
- Run the motor open loop in current mode
- Manually determined a start-up ramp profile in open loop
- Started up with speed control with my start-up ramp.
- Used the same MCSDK project with open loop disabled and motor profile enabled to generate a motor profile project with known good motor electrical model and start-up ramp.
Despite this, I see no change in behavior during the motor profile process when compared to the default project. I have used the startup speed as my max speed, lower, and higher. I have changed the max current to the same as my start-up profile and to the max the board can handle. No luck.
I am using the following versions:
- ST Motor Pilot V6.4.1
- Motor Control Workbench Version: 6.4.1 Build: 250722.074358
- STM32CubeMX V6.15.0
- VS code with STM32CubeIDE for VS code version 3.6.4
Any help or tips would be greatly appreciated! Let me know if there is any other information I can provide!
