synchronous motor voltage tolerance?

[matt_WA]

Hello all,

Our evaporative air conditioning unit had a error code that was the drain module was not working. On closer inspection the module was fine but the synchronous motor had some corrosion on it. After inspection this 24VAC synchronous motor needed replacing.

The drain module is a synchronous motor, 2 micro switches and a small plastic drain part. I contacted the service guys for a quote and the module was $350 Australia dollars!!! The rest of the module was fine so I was looking on ebay for a 24VAC synchronous motor.

These 24V ones are rare but 21VAC motors are very common.
What would be the voltage tolerance like on a synchronous motor? Would 24VAC be ok for a 21VAC one?
That is approx 15%. I cant find a datasheet on it

This is the unit I will get:-
http://www.ebay.com.au/itm/21VAC-Mi...or-SM16-BY36M1A6-/160370454517#ht_3120wt_1037

but cant find a datasheet on it neither..
SM16
BY36M1A6
21VAC
50 / 60 Hz
5 / 6 RPM
3 / 2.5 Watts
MFG EleNsys

The power/RPM/frequency is the same as the faulty one just the 3V volatge difference.

Any help appreciated
Thanks

I don't have an answer to your question but i do know a link for a much less expensive replacement for your original 24VAC synchronous motor. Cost $10 US.
I have ordered 6 of them and they work fine (in an arcade game not an air conditioning
unit.

Good luck and here's the link:
