An alternating current motor comprises a non-magnetic frame with bearing screens in which a cylindrical core made of wedge-like sheets of electro-technical steel is fixed, on its inner surface radial slots with cylindrical recess at the middle are provided, there are two armature windings and at front sections of those. At the outer surface there is a three-phase coil winding and slots for conductors for connection of front sections of the armature windings, at the end sections – a conical depression for elements for fixation of the sheets of the core. The motor includes a ferromagnetic armature with shaft and spiral narrow teeth and slots at the outer surface of the first one. The windings of the armature “squirrel cage” are arranged as short-circuit, made of aluminum by method of continuous casting. |
