Technical Field

[0002] In existing electric vehicles, permanent magnet synchronous motors are their main power source. However, there are some problems with the existing methods for fixing the three-phase wires of permanent magnet synchronous motors. First, the traditional fixing method usually adopts clamping or loose fixing, which causes the connection to loosen and the buckle to break due to long-term vibration and friction, affecting the stable operation of the motor. Secondly, the existing fixing method cannot effectively prevent the vibration generated by the motor during operation from affecting the three-phase wire, which may cause the performance of the motor to deteriorate and may even cause electrical failures. To this end, a pipe clamp bracket for the three-phase wires of permanent magnet synchronous motors of electric vehicles is proposed. Summary of the invention
