Synchronous Motors for Projectors or Tape Machines

Product Details:
Bodine 230v synchronous projector motors are the cats meow for many projects, not the least of which is replacements for theater projector motors. They achieve and lock in at 1200 rpm! When operated in reverse, or when the shaft is driven by a wind propeller, once 1200 rpm is achieved, the voltage and frequency output is constant regardless of small speed variations. Most generators have a transmission to convert prop rotations to generator requirements. 5.5" diameter x 7.5" long body.

Product Details:
Synchron turntable motors from the once famous Weathers turntable. A synchronous motor achieves its predetermined rpm and stays there. In this case, 600 rpm. Shaft rotates clockwise looking at shaft end. Brand new excess from Compass Technical, the last producer of Weathers products from the 1960's.

Product Details:
A selsyn, or synchro is a motor which when wired to one another and the shaft rotates, the other shaft rotates in synchrony, keeping a constant angular position relationship with the first shaft. Packaged in vacuum cans from 1954! 90 / 55 vac, 60 Hz. Synchronous for "U.S. Navy Bureau of Ordinance", maybe a torpedo or radar? Made by Magnovox. Can marked "Type 1 HCT Mark II Mod 5". 3/16" threaded shaft with nut will mount up to anything. 2-1/8" diameter, 3-3/8" long body. 1.25 pounds each. We were very excited to find these. Only about 60 left.
