I have a RD Step Motor with the number 23hd5047-24b. Could you tell me if you have an equivalent replacement  
33V 1.45amp power supply input.  
It is approx 50mm sq and shaft is approx 30mm

Hi Karl,

Welcome to the forum!!

This is a style of a NEMA23. From what I found on the web this would be the closest thing we have: [https://core-electronics.com.au/stepper-motor-bipolar-200-steps-rev-57-56mm-2-5v-2-8-a-phase.html](https://core-electronics.com.au/stepper-motor-bipolar-200-steps-rev-57-56mm-2-5v-2-8-a-phase.html)

I cant confirm that it would definitely work.  
PS: with stepper motors, you can overvolt the motor as long as the appropriate current limit is set.

Liam.
