Hi All,
This is my first post so I hope I've submitted to the right forum. I have a question about some stepper motors. I bought three Astrosyn Minebea 23LM-C373-01 6 wire stepper motors. The statistics are 12 v/phase, 0.44 A/ phase 1.8 Degrees/step. I am looking for a driver board that will work well with these steppers. I contacted Xylotex (sp?) regarding their 4-axis Unipolar board and was told that I would get poor performance as far as top speed and torque are concerned due to a high impedance (The motors are rated at 27 OHM). The response confused me... does that mean these are just poor motors for CNC use? Should I use a Bipolar driver instead? Any and all help is much appreciated.
