Model numbers on PRSalpha steppers?

[kgracey]

Hey there,

Can anybody tell me the model numbers, current and voltage rating of the PRSalpha stepper motors? I'm a flashcut CNC user and I'm sizing a box for new PRSalpha hardware.
Thanks, Ken

Ken, as far as I've been able to determine, the motors (pre-RBK) are electrically the same as the PK296A1A-SG3.6 motor, which means that it pulls 1.5A when wired full-coil bipolar series. Many of the motors were shipped with only four wires, which makes full-coil bipolar series the only choice.

So, the PK296A1A-SG3.6 motor (which is the same as the PK296-01AA motor electrically), is rated at 30.8 mH Inductance, 4.4 Volts, and 4.4 ohms resistance. the half-coil rating (if the motor has all six leads exiting the motor) is 7.7mH Inductance, 3.3 V and 2.2 Ohms resistance.
