I just purchased 3 - KL23H286-20-8B stepper motors and I am not sure what voltage and amperage power supply to buy. I have read several articles and I am really confused about what size to purchase. I am looking at the KL-320-36 36V/8.8A 110V/220V for $59.95 and I am not sure if thisis the correct choice. Here are the specs for the stepper motor that I bought. I am planning on running them in Bipolar mode.
NEMA 23 BIPOLAR STEPPER MOTOR 425 oz-in, 1/4” Diameter shaft with a flat KL23H286-20-8B (Dual Shaft) Specification Price: $49 Rated Current: 2.8A, Rated Voltage: 4.17V (in Bipolar Parallel)
