Dear TI team,

We have BLDC motor, the SPEC: 24V / 50W and maximum speed = 50000 rpm

We want to check that is InstaSPIN possible run the motor to 50000 rpm?

and could you suggest us what kind TI EVM (DRV8301 or DRV8312) can test it?

That depends on the electrical frequency of the motor, it's fine if the pole pairs of the motor is "1" or "2" and the PWM frequency is set to a higher number.
DRV8312 should be much better to spin this motor since it only has 50W power.
