Hello all,
I've been working on a simple little project the past few days that required a 110V AC 1 rpm motor. I was able to pick one up off eBay for very cheap (from China). When I first installed it everything seemed to be moving along just fine, but then I noticed something. My 1 rpm motor was moving FASTER than 1 rpm. After some timing of its rotation I noticed it was moving ~8 seconds too fast (That's one rotation every 52 seconds). The solution to this that I have is an AC Motor Speed Controller (That I have already ordered).
My question is two fold:
1. Is this the ideal solution?
2. What could be causing the motor to turn faster than its rated?
Here is a stock photo of the motor that I am using with all its markings.
