Selecting the right driver

[Lee Roberts]

Hi,

Well yea I know it would give error going over 50v, still need the questions answered please people.

Isn't the holdiong torque the same thing as "torque while moving" ?

Holding torues is at zero speed.
as soon as the motor starts to move the torque goes down.

I've just purchased the stepper noted in #8 [ Nema23 3Nm motor (PDF), the document said: Bipolar Parallel 2.73v, 4.2a, 3Nm], connected to my existing driver and hey ho smoke all around.

I’m very interested to know, did you decide on a driver as I clearly need to upgrade what I had ?
