I salvaged from an old microwave, the motor that spins the food tray. I'm trying to figure out how much voltage I need to apply to it in order to get it to spin, but I cant make any sense out of the numbers on it. It's a Synchronous Motor.
This is what's on it:
100/120v~ 50/60Hz 4W 4/4.8r/min CW/CCW
I can guess that it rotates from 4 to 4.8 rotations per minute? but other than that, I'm clueless. What do these other things mean? Thanks so much!
Taking a few guesses here, but:
100-120V~: operating voltage, "~" (tilde) indicates AC voltage
50-60Hz: operating AC frequency
4W: power consumption (maximum stall perhaps?)
CW/CCW: works in both ways (clockwise and counterclockwise.) This usually means it is a synchronous motor, and its direction depends on either the sign of the incoming AC waveform, or whichever direction has the least torque - in other words, it's more or less random.
CW/CCW - Clockwise & Counterclockwise. a lot of turntable motors for microwaves will alternate the spin direction to help even out cooking, each time it is powered up the spin will reverse from the previous time...
1st time, let say clockwise 2nd time, then counterclockwise 3rd time, clockwise again...
