Description
TECHNICAL FIELD

[0002] The motor needs to be fixed and protected during the transportation process to avoid the mutual vibration and impact between the stator and the rotor caused by the bumping in the transportation process, and further to cause the damage of the bearing of the motor. The current transportation protection method is to fix the motor stator and the motor rotor on the protection tooling. The protection tooling clamps the rotor along the circumference or connects with the end face hole of the rotor to form the positioning of the rotor, the connection hole of the protection tooling and the stator end cover is connected to form the positioning of the stator, the rotor, the stator and the protection tooling form a whole to reduce the mutual impact between the stator and the rotor. The current transportation protection method has several shortcomings:
[0003] 1. If the transportation protection tooling clamps the rotor along the circumference to position, the clamping of the rotor cannot form the support limiting of the end part of the rotor, the length of the rotor of the long shaft motor is larger, and the end part of the rotor is easy to bend and deform due to the swing in the transportation process. If the transportation protection tooling uses the positioning of the connection with the end face hole of the rotor, the connection with the end face of the rotor cannot be formed when there is no connection hole in the end face of the rotor.
[0004] 2. Only the radial positioning of the stator and the rotor is formed to prevent the impact on the bearing between the stator and the rotor, and the axial movement of the stator also exists in the transportation process to cause the noise of the movement and the impact on the internal structure of the motor.
