Title:
LINEAR ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS5574359
Kind Code:
A
Abstract:
PURPOSE:To reduce magnetic energy fluctuation and thereby reduce cogging by the structure such that pole teeth on two magnetic plates coupled via an armature coil are placed alternately in the longitudinal direction and each of pole teeth is provided with an auxiliary groove. CONSTITUTION:Magnetic plate 6 having L-shaped pole teeth 6a-6c and magnetic plate 2 having similar pole teeth 2a, 2b are coupled via armature coil 4 passing through magnetic spacer 3, and the respective pole teeth of magnetic plate 6 and magnetic plate 2 are arranged alternately in the longitudinal direction. Each pole tooth 6a-6c, 2a, 2b is provided with a plurality of slits, and an armature of a similar construction is coupled with two bolts 1, for exmaple, and is placed opposite field unit 13. By this, since magnetic energy variation is reduced by the auxiliary grooves, cogging is reduced.
