A.c. motor

A.c. motor

A.c. motor

(OP)
hi i have an A.c. motor which belonged to a washing machine and has a symbol written on its description which is : 13,000 n'  does anyone know what (n') mean???

RE: A.c. motor

It's not a familiar notation but quite probably could be rpm. Modern washing machine motors rotate at very high speeds, which allows them to produce quite large outputs from physically small motors.

RE: A.c. motor

On asynchronous machines I've seen n used to signify the speed of the rotating field and n' used to signify the speed of the rotor.

RE: A.c. motor

If you denote everything else that's stamped on the nameplate
it can be easier to eliminate, or get closer to a better guess.
My first thought was it's the motor's serial number, or model
number even though it's 13,000 which seems too coincidental.

What else is on the nameplate? That would help eliminate or
zero in on what the number represents.

high the motor is a universal motor  and btw no it's not the model of the motort, btw it has 1.9Amps, 350W, 220/230V, 50Hz cl. B/F and 13,000 n'

the model is MCA45/64 - 148/BK 10

RE: A.c. motor

This is hardly a question for professional engineers. You have found a washer machine motor and want to play with it.

Fair enough. But why shall we bother at all? It isn't an asynchronous induction motor but a brushed one. It is very probable that the "'" you mention actually is ^(-1), which is a common way of saying 'per minute' in some parts of the world.

The site rules are strict and do not allow 'hobbyist' posting. You may find that this thread disappears soon.
