Description
technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a surface-mounted magnetic steel assembly tool for a permanent magnet motor and a method for using the same. Background technique [0002] Compared with traditional asynchronous motors, permanent magnet motors have the advantages of small size, low heat generation, and high efficiency. They are more and more widely used in wind turbines, marine motors, and mining motors. Permanent magnet motor rotors generally use rare earth permanent magnet materials, which have strong magnetic properties and can provide a stable magnetic field for the motor. In the actual motor manufacturing process, magnetic steel assembly is a very important process node. The magnets of large permanent magnet motors are usually large in size and have relatively strong magnetic properties. At the same time, due to the long axial length of the magnetic steel of the same pole, in order ...
