Title:
LINEAR DC MOTOR
Document Type and Number:
Japanese Patent JPS61210864
Kind Code:
A
Abstract:
PURPOSE:To increase thrust and improve efficiency, by winding up the specified inserting grooves of a long-plate-formed core with a plurality of cables turn- toroidally. CONSTITUTION:The magnetic poles with N, S arranged alternately with the width T are provided for field magnets 5. A core 8 is provided with a plurality of grooves 7 for inserting armature coils vertical to the running direction of the field magnets, on the upper and lower surfaces, at intervals of T/2 or approx. T/2. Also on the upper and lower surfaces of the core 8, shallow grooves 9 in quantity n (n is a positive integer of 1 or more.) are formed with the width T/2 at equal intervals. The grooves 7 of the core 8 are wound up turn-toroidally with a plurality of conductors, and the first conductor sections 11a contributing to thrust are formed, and the terminal for the winding end of the first conductor section 11a is conducted to the position of the groove 7 separated by the magnetic pole width T of the field magnets 5 in the running direction, and one armature coil is formed by winding up the groove 7 position toroidally with the second conductor section 11b contributing to thrust in the direction opposite to the first conductor section 11a.
