Description
Technical Field
[0001] The utility model relates to the technical field of motor rotor production equipment, in particular to a rotor inner fan assembly mechanism. Background Art
[0002] The motor rotor is also a rotating component in the motor; the motor consists of two parts, the rotor and the stator. It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. During the assembly of the fan of the motor rotor, it is necessary to ensure the coaxiality between the motor rotor and the fan during the assembly process, so as to ensure that the fan is accurately installed on the rotor. The traditional installation method requires manual adjustment of the fan position and then use stamping equipment to assemble the fan to the motor.
