The 3 Phases

This NOS 12VDC 1A 3-coil brushless servo motor with 36 steps per revolution was for a printer, maybe. Or a scanner, maybe. Whichever, it's mounted on a 2-1/2" x 2" plate with a 3/4" long shaft with a 5/8" dia rubber wheel out one side and a 15-tooth, 2" dia plastic sprocket on the side with the leads. The white lead feeds a Hall effect sensor, then ground, +5V control, and then the three coil leads  Samsung P/N 02914900.

One Step At A Time

How about a really nice 4-lead stepper motor linear actuator? We thought so. This one is a roboticist's dream, and requires 570mA at 5VDC and features a 2-1/2" long 1/4” lead screw with a 3/4” long 3/16” ID U-joint at the end. Bipolar and non-captive. Measures 1-3/8" square x 1-5/16". But wait, there’s more: also has a 5-pin 5VDC 30mA encoder at the end. Everything is connected via a 14” wiring harness. Has (4) 3/32” mounting holes on the face. Whole shebang in made in the US of A. HSI Part# 35F4P-05-006. Encoder# E5S-1000-315-H.
