Multiple brushless motor control
Hello,
what would be the best way to control 4 sensored BLDC motors at the same time? Using 12 PWM channels for 12 phases, as well as 12 pins for Hall sensors is too much. I thought of using 3 4/1 multiplexers for hall sensors, and a single PWM for each motor via AND gates. What do you think?
Thanks

Harshad ItaliyaWelcome to CE!
Yes, in both way you can control BLDC motor and use of Multiplexer surely reduce your used IO Pins. 😛marinbHello,
