How to find whether the stepper motor is 12v or 24v?

i bought a bipolar stepper motor which has
phase current=450mA,drive frequency=50Hz, phase resistance 36 Ohm, step angle 7.5, and 4 wire connection type. but i dunno it’s 12v or 24v motor, how to find it?. thanks in advance

Hello.

Can you post a link to the stepper motor you purchased?

From the datasheet, it looks like your stepper motor is rated for a maximum current of 450 mA, and given the coil resistance of 36 Ω, applying a voltage of 16 V will get you to that max current. If you are using a stepper motor driver with configurable current limiting, you should supply it with more than 16 V if you want to get the full 450 mA.

many thanks, yes we’re using configurable controller and supply voltage is 24 V. Is it correct selection?

That voltage is okay when used with a controller with configurable current limiting.
