Abstract
A motor of the invention includes a stator having a slot wound with a coil and a circular shaped housing accommodating the stator, and a rotor disposed on an inner surface of the housing and spaced apart from the slot and having a plurality of permanent magnets having the same number as magnetic poles and having different magnetic polarities. Each of the plurality of permanent magnets has a length corresponding to a first angle according to the number of magnetic poles. The plurality of permanent magnets are spaced apart from each other at a third angle according to the first angle and a second angle corresponding to the number of magnetic poles. The first, second, third angles of the motor refer to a center point of the housing as an angle reference point. The motor of an embodiment may be a motor provided in a washing machine.
