My motors are rated for 3.2 volts at 2 amps, driven with 24 volt choppers.
Higher voltages are a problem for small, low-cost tools. The Xylotex drivers (3977 chip) max out at 35 volts, and the SLA7044 chip I'm using is similar.
I'd be very interested in hearing from others who use 23 frame motors on small tools. What step rates are you achieving?
Is anyone getting substantially more than 3300 steps per second, and if so, what kind of driver are you using?
