BLDC controllers for permanent magnet motors

Hi Team,

Our customer is looking for BLDC controllers for permanent magnet motor. According to our customer,

The back EMF of the motors range from 100-400V..but for now

If we can test controllers that can handle up to 150-160 Volts of back emf ..that would suffice…. The motor range from 8Nm to over 100Nm

Currently, we have a few BLDC motor drivers on stock, is the DRV8312, DRV8313 and DRV10982-Q1 suitable for these motors?

Regards,

Danilo

Hi Danilo,

Unfortunately our BLDC motor driver controllers can handle up to 100-V abs max of BEMF from the motor. DRV8300 can handle up to 125V abs max, but this may be too low your application.

You may need to look for a IGBT driver rather than a BLDC driver to handle over 100V of BEMF.

Thanks,
Aaron
