LINEAR DC MOTOR
Document Type and Number:
Japanese Patent JPS61210866
Kind Code:
A
Abstract:
PURPOSE:To obtain large thrusts with a simple and low-cost structure, by properly setting the magnetized width and pole quantity of a field magnet, and the open angle degree and quantity of the T-formed main salient pole of an armature with a core. CONSTITUTION:A stator armature 6 consists of a stator yoke 7, and an armature coil 11 group wound up around the straight pole section 10 group of T- formed main salient poles 8 formed on the stator yoke 7. Field magnet are arranged in quantity p (p is a positive integer of 2 or more.) and are provided with poles N, S with the magnetized width T. The T-formed main salient poles 8 of the stator armature 6 are provided in quantity m (m is a positive integer of 2 or more.), and magnetic pole pieces with the open angle degree of n.T (n is an odd number of 1 or more.) are formed.
