Title:
COMMUTATOR ARCUATE LINEAR MOTOR
Document Type and Number:
Japanese Patent JPS59230458
Kind Code:
A
Abstract:
PURPOSE:To obtain a motor which has a flat shape, a small size and a high efficiency in a compact structure by planarly securing a field pole onto a stationary substrate, and rotatably mounting a rotatable substrate oppositely to the stationary substrate. CONSTITUTION:The pole segments 2a of a field pole 2 are planarly secured in an arcuate shape on a stationary substrate 1. A rotatable substrate 3 formed of a nonmagnetic material relatively rotatable to the substrate 1 is composed by integrally molding with plastic a bearing member 4, a commutator 13 and armature windings 9-1-9-3. Brush holders 12a-12c respectively hold a normal rotation brush 11a, normal and reverse rotation common brush 11b and reverse rotation brush 11c. The commutator 13 has commutator segments 13a group which are slidably contacted with the brushes 11a-11c.
