How Do I Test A Synchron Motor

[dilligaf]

Hi, can anyone tell me the best way to test a synchron motor on a 3 port motorised valve?

You suspect the motor burnt out? Just whip it off and test windings with a multimeter, might need some spade connectors.

1. If:
1a. You know what you are doing, AND
1b. You are confident working with mains voltages, THEN
2. Connect one wire from the motor to blue, and the other to brown (doesn't matter which way round) of a cable.
3. Mains plug on other end of cable.
4. Plug it into the mains.
If the motor turns you are OK, but check the little pinion on the end to make sure it isn't too worn.

Okay and thanks for your reply, you've just confirmed what I was already thinking, I can do most things so this will be a doddle really...
Thanks again!

Helped a friend out last Saturday - his heating had gone down, he said the MV was clicking, but he couldn't get the lever across to manual. He came and collected a used synchron motor from a Honeywell 2 port I had.

Messaged me later to say he was up and away - heating back on!
