Stepper motor arrives

I didn't expect the stepper motor till tomorrow. It arrived, however, with the noon post.

Turns out that they went from the old style system which was a geared stepper to the new style which is lead and cadmium free but which also is gearless. They are pretty sure that it has the same torque reading, but the can measurements are pretty much the same, so I'd take leave to suspect that that's not so.

I pulled out the digital multimeter and measured the phase resistance and got 27.3 Ω which is just about what it said in the catalog. It will be interesting to see what sort of torque and speed that this thing delivers. Stay tuned.
