May 7th, 2008 Driving a Bipolar Stepper Motor
Jason writes:This entry shows the configuration I used to make a NMB (Minebea Electronics Co.) PM35L-048, 24VDC, 9.4 Ohm unipolar stepper motor work. I salvaged several of these motors from some Xerox inkjet printers. The motors were labeled well and I found manufacture specifications on-line. I was not able to find a wire diagram so I defaulted to making a truth table as I had done for unipolar steppermotors. Most steppers with 4 wires can usually be identified as bipolar stepper motors, which can be driven with a dual H-bridge IC such as the SN754410 by Texas Instruments.
