Steppers, Series, Parallel

Parallel works best for me, you get faster rapids and cooler running motors.

I have blown up quite a few drivers running in series due to the back emf/motor inductance.

That's a surprise because I tried wiring in parallel once. Once being the operative word. I got little appreciable speed advantage and lots more heat.

Also, why is everyone worrying about Volts, our drivers already have lots of Volts? Parallel wiring requires twice the Amps.

But aren't your motors on mains voltage, or something silly high, in which case it's hardly surprising that they would overheat in parallel?

See the post I linked to earlier - it's because the inductance is 4 times greater when in series, so you need a higher voltage to 'overcome' that.

They have what ever volts they are provided with.!! Give a 50V drive 24v and wire the motor in series and see how fast it goes or were it runs out of torque.!!

Volts make all the difference to a stepper and I'm surprised at that comment Robin.?
