I need to get a sync motor running and need help
The motor face place reads:
synchronous
voltage 120
frequency 60Hz
1 phase
torque 90inch ounces
capacitor .85mfd
it has 3 leads.
I measured the resitance on the leads as follows:
black blue red
o o o
| | |
--- 750 ohms -- -- 750 ohms ---
| |
------------1500 ohms----------
Question:
which leads do I hookup the 120V ?
which leads do I hookup the capacitor ?
what type of capacitor (.85mfd) do I use ?
what should the voltage rating of the capacitor be ?
PS
1) This is a motor used for a telescope clock drive.
2) The motor has a built in gearing so shaft rotates 2RPM
