Is it possible to run a Nema 42 stepper motor 110HZ150-210 with 36V at slow speed and 15N.m load (its holding torque is 21 N.m)? If it is possible then how?

The specs of the motor:

  • Step Angle: 1.8°
  • Current /phase: 6.5 A
  • Resistance /phase: 0.8 Ω
  • Inductance /phase: 15 mH
  • Holding Torque: 21 N.m
  • leads: 6 wires

Thanks.

  • Well, if the motor needs 6.5A, and you give only 0.5A, then it won't move. – tlfong01 Dec 25 '21 at 08:45
  • My driver modules set the current, so I simply run a lower voltage and current. – Kartman Dec 25 '21 at 11:57
  • @kartman So I just need a driver that sets the current? Do such drivers have a specific name? – nour hashem Dec 25 '21 at 12:13
  • @tlfong01. I was wondering if there is a way to supply the 6.5 amps at lower voltage that's all. – nour hashem Dec 25 '21 at 12:14
  • Leadshine DM542 or TB6600 for example. – Kartman Dec 25 '21 at 14:32
  • What's the current rating of your power supply? If the current rating is high enough, it'll work, and if the current rating is too low, it won't work. – Cassie Swett Dec 25 '21 at 14:50
  • @nour hashem, (1) Well, from the spec, I think you need a power supply of 36V with at least 6.5A. (2) For DM542 microstepping driver, you can set lower current, but not higher than 6.5A, because the max current is 36/R = 6.5A.
