Title:
SQUIRREL-CAGE ROTOR AND SQUIRREL-CAGE ROTOR MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/029529
Kind Code:
A1
Abstract:
A squirrel-cage rotor is equipped with a rotor (3) having a plurality of rotor slots (32) on the outer circumferential portion thereof and freely rotating inside a stator (2) by the interaction between secondary conductors (33) housed in the rotor slots and a rotating magnetic field produced by the stator. The rotor slots have the same shape and size and, within a slot irregular arrangement pitch (360°/a), are arranged in the rotational direction of the rotor at irregular intervals, said slot irregular arrangement pitch being obtained by equally dividing one rotation cycle of the rotor by a divisor (a) of the number of poles (p) of the stator.
