Segmented armature motor having a segmented coil frame having coil windings on the outer surface

摘要

Provided is a segmented armature motor, which includes a plurality of armature coils which enclose a rotor having a rotary shaft, an armature which houses the armature coil and which is coupled in a segmented form, a motor frame which is coupled to the armature so as to enclose the armature, and motor covers coupled to the front and rear faces of the motor frame. The segmented armature motor is formed so that the armature coils completely enclose a pole portion of the rotor and are formed into a horseshoe shape or U shape, thereby minimizing magnetic losses of the armature and of the rotor.

主权项

1. A segmented armature motor comprising: an armature having a plurality of frame supports formed protruding inward directions and frame fixtures formed protruding outward directions at intervals: a coil frame having a plurality of paired-coil frame support walls and coil frame partitions formed at intervals, the coil frame partitions being formed between inside of each paired-coil frame support walls, and the coil frame partitions being gradually widened in a radial outward direction based on the paired-coil frame support walls, each which are slantingly formed in a radial outward direction based on the coil frame, the coil frame comprising a first coil frame and a second coil frame, each of the first and second coil frame being formed as symmetrical hemisphere; a rotor inserted into the coil frame and having a rotary shaft; a paired dielectric sheet is mounted between the first and second coil frame; and a plurality of armature coils formed at each of the coil frame partitions of the coil frame, wherein each of the plurality of paired-coil frame support walls is inserted between the plurality of frame supports, wherein each of the plurality of armature coils is formed in such a way that an interval thereof is as gradually widened in a radial outward direction on each of the coil frame partitions of the coil frame.
