My motor don't rotates alone unless I manually make it rotates first

Hi,

When I flash a code that contain to start the motor (MC_StartMotor1) or press start on ST Motor Pilot, my motor doesn't manage to rotate on its own. It's like it is stuck and need help manually to finally be able to spin. 

Any idea what could be the issue and how to solve this?

Physical abstractions (a deformation or a piece of iron,... that does not let it rotate or a manufacturing defect).

Also try to increase the current to 5 or 6A and increase the RPM to 500 . That may give it the power he need to start.

Best regards.

Hello @Gnahore 

I think it is most probably a mechanical issue in the motor. I suggest you to check for physical abstractions. Also, check your motor health and alimentation (if the power the motor receiving is suffisent or not).

Best regards.

Hello @Issamos 

What is "physical abstraction"? Here is some info about the motor.

I set the generator (supply) at 36V, the current at 3A and the RPM max at 200.

have you imported your Motor from the .json generated by the motor profiler on the MC Workbench? after running the Motor on the motor profiler, you can click on "Gui" at the top left then load the "MC_FOC_SDK.qml" file and try to start the Motor directly.

Yes I did and this is what I am doing right now but the motor doesn't spin on its own unless I help it first. It want to rotate but it can't. Which is a bit surprising because the motor profiler have no issue making it spin.

Try setting the speed a little higher. on your document it is indicated 600RPM so the motor can go beyond 200RPM
