ABSTRACT:
A single phase asynchronous motor with two magnetic poles, of the type comprising a cage rotor and a stator having laminations provided with radial slots (A, B, C, D, E, F) and a main coil and an auxiliary coil each having coil turns, the turns of which are introduced in said slots. Slots (A) in the main coil axis (PP) adjacent to the slots (A, B, C, D, E) in the main coil have a reduced height at least in relation to the height of the adjacent slots (B) for the main coil, and said slots (A) of reduced height receive a number of coils lower at least than that which is received in said adjacent slots (B) in the main coil.
