Abstract
To provide a motor that can rotate a rotor without contact using a simpler structure.SOLUTION: A first portion has a base portion and a plurality of permanent magnets provided at the periphery of the base portion. A second portion has a housing and a plurality of coils at a position at the inner periphery of the housing and opposite to the plurality of permanent magnets. The plurality of permanent magnets has a first group of permanent magnets magnetized in a first magnetization direction along the rotation direction and a second group of permanent magnets magnetized in a second magnetization direction intersecting the first magnetization direction.SELECTED DRAWING: Figure 1
