MCT8316ZTEVM: Question about MCT8316 drives different motors

Jenson

Part Number: MCT8316ZTEVM

Hi Team,

I would like to know what difference does MCT8316ZTEVM have to drive different motors?

For example: One motor only needs 10% PWM Duty to reach 50RPM, while another motor needs 30% PWM Duty to reach 50RPM. Which parameters of the motor are related to this? Why?

Thanks

Hello Jenson,

That would probably be the Back EMF constant - the motor requires a certain voltage to reach a certain speed based on how much back-EMF that it generates.

Thanks,

Matt
