Hi All,
I have a motor and most of it's control circuit out of an electric hoist, but not the motors name plate. It takes 3 phase AC input, coming out of a nominal 415V installation. I know the motors power rating is 0.36kW as that happens to on the side of the housing.
Coming out of a hoist, I figure it could be either dual voltage or some sort of two speed such as a Dahlander motor (and motor identification is a whole new thing for me). As removed, it was wired in a Wye/Star configuration (i.e. L1 > U1, L2 > V1, L3 > W1 and then U2, V2 and W2 were bridged together).
Is there an easy way to check just by looking at resistance in the windings to deduce if it's say a 380/415 dual voltage motor, rather than something more complex?
The motor has two sets of wires coming out with each set consisting of 3 wires (labelled as U1, V1, W1 and U2, V2, W2). My starting assumption is that these are for the field windings, and represent each end of a given winding (i.e. U1 and U2 are each end of the U field winding). It's not very easy to actually see what's going on with the motor windings due to it's housing unfortunately. Is there a way to identify the type of motor from just the wire ends?
Any help would be appreciated!
