Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to an insulating skeleton structure of a three-phase motor. Background Art

[0002] A three-phase motor is one in which a rotating magnetic field is generated when three-phase alternating current is applied to the three-phase stator windings (with a phase difference of 120 degrees). This rotating magnetic field cuts through the rotor windings, thereby generating an induced current in the rotor windings (the rotor windings are closed paths). The current-carrying rotor conductors generate electromagnetic forces under the action of the stator rotating magnetic field, thereby forming an electromagnetic torque on the motor shaft, driving the motor to rotate. The direction of motor rotation is the same as that of the rotating magnetic field.

[0003] During motor manufacturing, the stator of the motor generally needs to be padded with an insulating layer and varnished when the coils of the enameled wire winding are embedded to improve the insulation performance of the stator armature. In the prior art, a motor insulation frame is usually used for isolation and insulation. However, the current motor insulation frame has a single function, generally only serving to insulate the enameled wire and the silicon steel core.

[0004] In addition, the existing motor insulation frame requires soldering, resistance welding and other processes during motor assembly, which has low assembly efficiency, is inconvenient to operate during the winding process, and the winding is uneven and inconsistent. The winding process is prone to the risk of wire damage and poor contact between the three-phase terminals and the enameled wire.

[0005] Therefore, it is necessary to design an insulating skeleton structure that is convenient for fixing the coil. Utility Model Content

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a three-phase motor insulating skeleton structure, comprising an insulating skeleton, an inner wall of the insulating skeleton is fixedly connected to a winding post, the other end of the winding post is fixedly connected to a baffle, and a socket is provided on the left side of the front end and the right side of the rear end of the inner cavity of the winding post, the bottom of the inner cavity of the socket is fixedly connected to a conductive post, the bottom of the conductive post is fixedly connected to an external wire, the other end of the external wire passes through the outside of the insulating skeleton, the inner cavity of the socket is threadedly connected to a fastening bolt, and the other end of the fastening bolt is located on the surface of the baffle.

[0008] Preferably, the insulating frame is made of engineering plastics, and its surface is sprayed with insulating paint.

[0009] Preferably, the winding post adopts a conical design, and the baffle adopts an arc design, and is designed to be concentric with the insulating frame.

[0010] Preferably, a threaded design is adopted between the jack and the conductive column, and the external wire and the conductive column are fixed by soldering.

[0011] Preferably, a circular hole is opened on the surface of the insulating frame, and the external wire passes through the inner cavity of the circular hole.

[0012] Preferably, the surface of the fastening bolt adopts the same arc-shaped design as the baffle, and the surface of the baffle is provided with a groove for accommodating the fastening bolt.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model inserts one end of the enameled wire into the socket at the rear end and rotates the matching fastening bolt to make the enameled wire contact with the conductive column and energize it, and then the winding work can be carried out around the winding column. After the winding is completed, the other end of the enameled wire is inserted into another socket and the matching fastening bolt is rotated. At this time, the fast winding work can be completed, and then the wiring work can be completed by arranging the external external wiring. By adopting this equipment, fast and efficient winding work can be achieved, and the neatness and consistency of the winding can be guaranteed. There is no risk of wire damage during the winding process, thereby avoiding the phenomenon of poor contact and ensuring the production quality of the three-phase motor.
