Document Type and Number:
Japanese Patent JP2017189090
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a new-typed single phase motor rotor which can improve the starting reliability, and a single phase motor using such a rotor.SOLUTION: A single phase motor includes a stator and a rotor. The stator includes a stator core. The stator core includes an outer yoke and a plurality of stator teeth. Each stator tooth includes a winding portion and a pole shoe coupled to the winding portion. The rotor includes a rotor core and a plurality of permanent magnets. The plurality of permanent magnets are evenly spaced and embedded in the rotor core. An outer circumferential wall of the rotor core is an irregular cylinder and includes a plurality of spaced circular arc surfaces and transition surfaces. The starting of the single phase motor is stable and reliable. The present invention also provides a rotor for the single phase motor.SELECTED DRAWING: Figure 2
