Description

Collector ring structure

This creation is related to a slip ring structure for motor stator, especially a slip ring structure that can reduce the overall thickness of the motor.

Conventional motors can be divided into three-phase motors and single-phase motors according to their types. A stator and a rotor are arranged in the housing of the three-phase motor. The stator is fixed on the housing of the motor, and the rotor is rotatably arranged in the center of the stator. A plurality of coil windings are symmetrically distributed on the stator, and these coil windings can be divided into three groups according to the polarity. When in use, a three-phase power supply can be input to generate a rotating magnetic field, thereby driving the rotor to rotate.

The prior art three-phase motor stator includes an iron core composed of laminated silicon steel sheets. The inner ring wall of the iron core is provided with a plurality of I-shaped columns at intervals, and each I-shaped column is provided with a coil winding. Each coil winding is connected by wires in a specific connection sequence to form a corresponding phase. However, the cross section of the wires is usually circular, which makes it impossible to stack closely, wastes space, and makes it difficult to reduce the size of the motor.

In view of this, the creator has accumulated many years of research and practical experience in related fields, and specially created a collector ring structure to improve the lack of the above-mentioned conventional technology.

The main purpose of this creation is to provide a collector ring structure that uses a flat connection plate and a neutral connection ring to replace the circular connection wire, which can reduce the volume of the three-phase motor.

The outer frame covers the conductive parts of the connecting plates, and the power input parts of the connecting plates protrude outside the outer frame. In this creation, a plurality of flat connecting plates and neutral connecting rings are used to replace the wiring harness for connection, which can reduce the thickness and the size of the motor.
