Motor rotor and cable connection structure thereof

Abstract

The invention discloses a cable connection structure of a motor rotor. The cable connection structure comprises an outgoing cable, a winding lead wire as well as a conductor connector arranged between the outgoing cable and the winding lead wire, wherein a wiring end of the outgoing cable and a wiring end of the winding lead wire are connected with the conductor connector. The cable connection structure of the motor rotor is mainly used for connecting and fixing the outgoing cable and the winding lead wire. The conductor connector is arranged between the outgoing cable and the winding lead wire, and the wiring end of the outgoing cable and the wiring end of the winding lead wire are connected with the conductor connector, so that the smoothness of a circuit is guaranteed by the outgoing cable and the winding lead wire under the action of the conductor connector; more importantly, the outgoing cable and the winding lead wire are connected with the conductor connector respectively, and compared with the prior art, the outgoing cable and the winding lead wire can be prevented from being pulled apart due to the fact that the outgoing cable and the winding lead wire are relatively shortened respectively under the action of the centrifugal force.

Description

technical field [0001] The invention relates to the technical field of electromechanical engineering, in particular to a cable connection structure of a motor rotor. The present invention also relates to a motor rotor comprising the above-mentioned cable connection structure. Background technique [0002] With the development of China's mechanical engineering and electric power technology, the field of electromechanical engineering technology that combines the two is also growing, and the motor is an important hub connecting the two technical fields of mechanical engineering and electric power engineering. [0003] The overall model structure of the basic motor is relatively simple, and the core components include the stator and rotor. Taking the rotor as an example, the rotor is generally provided with wiring devices such as windings and cables, such as three-phase cables and winding coils. When the rotor is in operation, a three-phase cable needs to be connected to the w...

AI Technical Summary

Problems solved by technology

[0004] However, due to the high-speed rotation of the rotor during normal operation of the motor, the outgoing cables and winding lead wires will be subjected to huge centrifugal force

Since the terminal of the lead-out cable is directly connected to the terminal of the winding lead-in wire, under the influence of high-intensity mechanical vibration and mechanical stretching, the connection between the lead-out cable and the winding lead-in wire is likely to be torn off when pulled. As a result, the motor is suddenly interrupted during normal operation, and the reliability of the safe operation of the motor is not high.
