Description

Technical Field

[0001] The utility model relates to the technical field of precision assembly of split-type permanent magnet motors, in particular to a rotor assembly device for a split-type permanent magnet motor. Background Art

[0002] After the permanent magnet motor is manufactured, it does not need external energy to maintain its magnetic field, and the permanent magnet poles are installed on the rotor. Since the permanent magnet rotor is very magnetic, it is very difficult to install the rotor into the stator. If no measures are taken, once the rotor contacts the stator core, the two will be firmly sucked together, making it difficult to adjust again, and strong adjustment can easily cause damage to the magnet. When operated manually, sometimes the attraction is too strong and the two approach too fast, squeezing or hitting the operator's hand. Large permanent magnet motors have large stators and rotors, and the magnetic attraction is very large. The impact force at the moment of adsorption is very large, which will damage the magnetic steel sheets embedded on the surface of the stator and armature, thus causing unstable motor performance.

[0003] Due to the particularity of permanent magnet motors, when the rotor is transferred to the stator, assembly tools are generally used; the existing assembly tools can only assemble motors of one specification and size. When motors of different specifications and sizes need to be assembled, different assembly tools need to be replaced. The adaptability of the assembly tools is poor, and the assembly tools have a complex structure and are inconvenient to use, resulting in low motor assembly efficiency. Utility Model Content
