Description

Motor stator and rotor dismounting device
Technical Field
The utility model relates to a motor dismouting field especially relates to a motor stator rotor dismouting device.
Background
In the field of test development of power motors of energy automobiles, separation of a stator and a rotor of a motor is a frequently encountered work content. No matter in the post-test inspection, the test problem investigation or the quality inspection of the installation of the prototype, the disassembly of the prototype is an essential step. According to development experience, the separation times of a prototype in a general product development project are 50-100 times.
In the structure of the driving motor for the vehicle, the stator and the rotor are connected by a high-speed bearing, and the high-speed bearing is tightly matched and is usually in interference fit, so that a larger acting force is required for separating the stator from the rotor. In addition, the most commonly used motor among the driving motors for vehicles is a permanent magnet synchronous motor, and a magnetic force exists between a stator and a rotor. To separate the stator and the rotor, the resultant force of the two acting forces must be overcome, which is very large for a common operator, and the separation cannot be smoothly realized by means of a hammer, a crowbar and other manual tools, and the separation can be realized only by means of an external force.

In the process of combining the rotors together, due to the action of electromagnetic force, the force balance can not be realized when an operator operates the rotors manually, and the stators and the rotors are inevitably collided and scratched.
