Part Number: MCF8315A

Hi,

Can I use MCF8315A or MCF83EVM to control 24V, 3 Watt, AC synchronous motor? If you need motor details, please PM me.

Or, if you have better suggestions for AC synchronous motor controller, please let me know as well.

Thanks,

Does your motor have permanent magnets on the rotor? if yes, then you can use MCF8315A to drive your motor.

Hi,

MCF8315 is 3 phase. The Motor that I'm trying to control is single phase. Do you have PMSM controller with single phase? Thanks

Unfortunately, we do not have single phase motor drivers.

Hi,

Thank you. Basically, stepper motor driver with 4w1-2 phase excitation will work. If you have any please let me know. Below are a few datasheets that has 4w1-2 phase excitation?

Let me assign this to Brushed and Stepper Motors team.

Hello,

By 4W1-2 Phase Excitation, I think this is the same as our 1/16 microstepping mode. Many of our stepper motor drivers support microstepping. See the following link, any driver with 16 or 256 microstepping levels will be able to do 1/16 microstepping: https://www.ti.com/motor-drivers/stepper-driver/products.html#2894=16%3B32%3B256&

24V 3W is 8 amps, our only stepper motor driver with microstepping that could drive this load is the DRV8462.
