hello everyone,
someone can tell me what the maximum volts and amps to use this stepper motor? the model is EM-400 recovered from a epson stylus color.
thanks for your answers.
greetings
I do not have the data but I am using it for years at 600mA in a 3D printer. I won’t use it for a CNC though (it is even weak for a 3D printer).
ok thanks!
I’m currently using with 12V 2A but is reaching very high temperatures.
I’m using them on a small prototype cnc laser
Modern stepper drives limit current, so the voltage you feed the motor is of lesser importance. As long as you do not exceed the insulation breakdown voltage you are OK. What current you run at is critical though.
You didn’t take that motor apart did you? If yes you might as well toss it. Because taking a stepper motor apart breaks the magnetic circuit inside of it, and weakens the magnetism it has. It has to do with the keeper effect. Reassembled stepper motors cannot generate the torque they used to. The loss is something like 90%. Torque is important with stepper motors too.
It is very nice motor!, I’m using with 24V 5A but drive by L297 with current control.

A L297 is a sequencer. It is usually connected to a dual bridge to do the actual driving. A L298 is a popular pairing.
Yes! You are right!
Have a look at the two following links:

I know from my own personal experience that L297 and current control give the best results.
I forgot, I’m driving the engine when the driver a4988
in any case, thank you so much for the answers
@Mirco_Slepko
at 12 volts you are not going to get good high RPM performance. You need to increase the voltage.
