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.

A Breath Of Fresh Air

That’s us, a breath of fresh air in the shopping atmosphere. Also, your source for these surplus Swiss-Air™ II Freshener Systems--one with a motion activator, and one without (you pick). Originally took cartridges that freshened the air with cherry, orange, berry, potpourri or other scents. Do they work? Might could, as they say in Nowth Car’lina, but we’re selling them for parts. The wall-mount cases measure 7-3/4" x 3-1/2" x 3-1/8” in cream plastic, with a cover that comes off to reveal a dandy 1.5V motor with a 5-blade fan, and terminals for a D cell battery. Motor is 1” dia x 1” long, shaft is 1/16” dia x 3/8” long, and fan blade is 2-3/8” dia.
