Title:
LINEAR MOTOR
Document Type and Number:
Japanese Patent JPS5925571
Kind Code:
A
Abstract:
PURPOSE:To contrive to manufacture the linear motor in a small type, while to obtain a large thrust by a method wherein leakage flux at the leg parts of field is reduced by making properly the magnetizing direction of permanent magnets and arrangement of the leg parts of the field. CONSTITUTION:A movable element 7 is constructed of cores 71, 72, 73 of the plural number having respectively the field legs of the plural number, the permanent magnets 40 having the duty to supply bias magnetic flux to the cores 71, 72, 73 thereof, the permanent magnets 411, 412, 413 to be interposed at the respective field legs between the cores 71, 72 and 72, 73, exciting windings 61, 62, 63 of the plural number wound around extending over the cores 71, 72, 73, and a traveling means to support the movable element 7 linearly reciprocating motion freely in relation to a traveling passage 5 holding the necessary interval between them. The groups of poles teeth are formed at the respective edge parts of the respective field legs facing to the traveling passage 5.
