Hi everyone,
A friend of mine came across what appears to be some sort of servo motor, and we are having trouble identifying it. Any help anyone could give would be appreciated, here is what we have so far:
Motor specs:
Torque Systems Incorporated
An EG&G Rotron Co.
Waltham, MA USA
Model No. MT-2015-017U4G10
Dual motor shafts, 1/4" dia.
Motor diameter: 2.02"
Motor case length: 5 3/4"
Windings are 0.014" diameter copper
The motor is labeled "PM Field DC Servo Motor" and has one of those ancient DC generators as a speed output (pretty much a 2nd brushed motor going along for the ride). I ran the motor at various voltages, measured the rpm with an external tachometer, and measured the voltage from the generator. I've never played with one of these before, and I was (literally) shocked at the results. At 45.8 VDC to the motor (the highest the DC power supply I'm using can go), the motor hit 7414 rpm, and the output of the DC generator was 102 Volts! Yowza! (Here I was expecting something like 5-12V.)
Anyone familiar with this era of technology have an idea of what this motor is supposed to be running at? At no load I measure the following:
3773 rpm @ 24.0 V, ~0.28 A, Vgenerator = 52.5 V
5767 rpm @ 36.0 V, ~0.30 A, Vgenerator = 79.4 V
7414 rpm @ 45.8V, ~0.30 A, Vgenerator = 102.4 V
At stall, it pulls about 3.5 A @ 24 V. (I wimped out on higher voltages.)
Any help anyone can give us, I would appreciate it!
Thanks
