Seeburg 50hz motor capacitor discussion

[dberman51]

Thanks Norman, I don't know about the 100-77, but on the DS-160 the motor is mounted such that its data plate is clearly visible with the mech cover removed and the mech scanned over towards the left. The DS-160 motor specifies RPM at 1600 on 60 Hz. This immediately identifies the motor as the AC Induction type, which always operates at a somewhat lower speed than the synchronous line frequency. A synchronous 4-pole motor would run at 1800 RPM (exactly) on 60 Hz, 1500 on 50 Hz.

Best,

-David

Here is a link to the motor in the 100-77

1400 RPM at 60hz.

Thanks for posting the link. Sure explains why Ron said that Bodine and NIDEC motors are not interchangeable. The gearing would have to be different.
