Brushless motor speed control using Arduino

Postby prabudda » Tue Mar 31, 2015 3:08 am


I am planning to use BLHM5100KC-GFS motor with an Arduino .My application require to control the speed of the motor using Arduino.Since the speed can change by supplying an analog voltage to the speed controlling pins of the motor driver ,Is it possible to use a PWM signal instead of Analog signal?

Hi prabudda,

We've never performed this type of test on our products. The BLH driver is designed only to accept a 0~5VDC analog signal so I'm not sure if PWM would work even though it seems it should. I think it's worth a test but be careful since this won't be covered under warranty.
