Abstract
A linear motor capable of improving power efficiency while preventing enlargement. A winding core direction of a coil coincide with a thrust direction of the linear motor. A center yoke is arranged inside the coil extending in the thrust direction. A magnet faces the center yoke outside the coil so that its magnetization direction is perpendicular to the thrust direction. A back yoke adjoins the main magnet at an opposite side of the center yoke. Two sub magnets adjoin the main magnet and their magnetization directions are inclined by 90° to that of the main magnet. Two side yokes adjoin the center and back yokes at both sides a magnet group in the thrust direction. Surfaces of the main magnet that adjoin the sub magnets incline inward toward the back yoke. Surfaces of the sub magnets that adjoin the main magnet incline inward toward the center yoke.
