Question

STSPIN32F0: Why does BLDC Motor stop with a Speed Feedback Fault on Loading it?

Hello All,

I am using STSPIN32F0 controller to run a BLDC motor at 1400 RPM. I am using ST Motor Control Workbench and IAR IDE for my project.

Motor Design Specs:

Rated Voltage: 36V

Rated Current: 10Amp

Rated RPM: 1400 RPM

My Motor Starts without any issues
Till the Motor is loaded up to 2 Amps, it works perfectly well
If More than 2 Amp is loaded, the Motor fails to RUN and a SPEED FEEDBACK ERROR or OVER VOLTAGE ERROR is generated.

What can be the problem?

Need your support as soon as possible.

Thank you

Ritul Shah
