RE: DRV8308: RPM of EVM

Garig,

I apologize for the frustration. The motor model information should be included in the User's Guide. Doing a quick search on E2E, I find the following thread which also has your answer:

e2e.ti.com/.../490559

The hardware files for the EVM in the tool folder contain the motor specs.

That being said. The EVM doesn't have an RPM min/max as this is dictated by the number of poles that the motor has. Any BLDC motor accepting up to 32V can be used.

From datasheet section 7.4.1: The DRV8308 device is designed to support a wide range of motor speeds and constructions. Speeds of up to
approximately 50000 RPM are supported with motor constructions of up to 16 poles, or corresponding lower
speeds with more poles. This translates into a Hall sensor speed of up to 6.7 kHz. (The frequency of one Hall
sensor can be calculated by RPM × (motor poles) / 120.)

Regards,

-Adam
