The invention discloses a damage prevention dismounting device and a dismounting method of a small-scale motor. The motor comprises a stator, a rotor arranged inside the stator, a first end cap and a second cap, wherein the first end cap and the second end cap are arranged at two ends of the stator and in interference fit with the outer end face of the stator. The steps are as follows: step 1, a rotor and stator dismounting device is adopted to dismount the motor into two parts, wherein the stator is connected with the first end cap, and the rotor is connected with the second end cap; step 2, a rotor dismounting device is adopted to dismount and separate the rotor from the second end cap; and step 3, a stator dismounting device is adopted to dismount and separate the stator from the first end cap. With the dismounting device and the dismounting method, the motor can be dismounted conveniently, and damage on the stator and the rotor in the process of dismounting can be effectively avoided.
Description
technical field [0001] The present invention relates to a dismantling device and method for a motor, in particular to a dismantling device and method that can prevent rotors and stators from being damaged. Background technique [0002] With the advancement of automobile technology, the application of automobile motors is becoming more and more extensive. Some transmissions also use a brushless DC motor to provide power for the realization of the electromechanical control of the transmission. The DQ200 motor described below is an example. The structure of the motor see figure 1 as well as figure 2 . This type of motor 90 includes a stator 91 , a rotor 92 disposed inside the stator 91 , and a first end cover 93 and a second end cover 94 with interference fit between both ends of the stator 91 and the outer end surface of the stator 91 . The stepped hole in the center of the first end cover 93 and the second end cover 94 is fitted with a bearing along the direction away fro...
