Greetings,
I'm building control panel for 5 BLDC motors.
My question are:
1. Can BLDC be controlled with PWM?
I ask this because brushless DC motors are electronically commutated. So in fact I'm messing up allready electronic pulses that drive originally coils.
2. If they can be controlled with PWM, which PIC to use?
PIC 16f628 has only one PWM channel and 16f876 two channels, I need 5 that have diffrent signals on it, in the same time.
3. Well I want to control all 5 motors and since I never used PWM in PIC, does PWM work in background like TMR0?
Because I want to have graphic percentage of speed of all 5 motors on LCD. Also pushbuttons need to be read for control of motors, all in the same time.
Thank you.
