#133664 - What speed range? Responding to: ???'s previous message |
Over what speed range do you need to vary the motor? At some point it's better to make a variable speed inverter. Electric motors don't mind running on RMS sized square waves. These are easy to generate with a microcontroller. The hard part is the high voltage/current switching. Take a look at IGBT's |
