110v ac motor controlled by 24v driver-controller board?
110v ac motor controlled by 24v driver-controller board?
(OP)
Hello,
We have a driver-controller board that was engineered to run a 24v DC motor using a microcontroller. The board also has a 5v step-down curcuit to power the microcontroller.
We want to use this board to drive a 110v AC motor. Does anyone know of an add-on curcuit or design to accomplish this?
Thanks.

If all your board did was turn this DC motor On/off and nothing fancy, like speed control. My first thought would be to insert the control input of a solid-state relay into your curcuit in place of the DC motor. And use the output of the SSR to control the AC motor.
If it did fancy stuff, like speed control, that's a different thing altogether.
Might be other ways, that just strikes me as easiest.
Hope that helps.

maybe strongly recommend to use a driver intended for AC motor control due to significant difference of control methods for AC and DC mootrs.

Any suggestions on where to find a AC motor driver for this?
I'm using the Nat Semi LMD18245 for the motor now.
Will I need a starter for the AC motor?

Your question needs a little clarification. What looked like a straight forward replacement of a DC motor with an AC, now appears different. As, a quick look at the data sheet for the LMD18245 shows it to be a driver for a stepper or DC servo. This takes the simple replacement question into a different area.
Could you send a little more info on your system?

Ok, it's a 2 phase stepper motor 3A, 24v DC. I use 2 of the LMD's and they are controlled by a microcontroller.
Did you need anything else?
Thank-you.
