Hi,
I have a 24V, 1.5A output power supply. This is driving a stepper motor with some control circuitry inside a box. The motor is a 2-phase stepper motor with max 2A per phase (as per the datasheet). There are 4 wires coming from the stepper motor (A+, A-, B+, B- labels). I took one of the phase wires and ran it through a digital multimeter to measure the current and it shows the DC current max as 2.9590A and the min as -2.9700A. Can someone tell me how this is possible? I though a 1.5A power supply will allow at most 1.5A in a circuit.
Thanks for your help.
P.S. we tried the same test with a 24V 3.0A power supply and got identical results as the 1.5A supply.
Best,
Mike
