Abstract

The invention discloses a method of manufacturing a straight-winding thin-wall hollow rotor cup, which comprises steps of coil winding, wire arrangement, primary reinforcement, welding, heating and setting, secondary reinforcement and the like. The secondary reinforcement step comprises sub steps of insulated potting, vacuum gas escape processing and stepwise solidification processing sequentially on the winding coil, and after cooling and demolding, the straight-winding thin-wall hollow rotor cup is obtained. The problems that the straight-winding thin-wall hollow rotor cup in the prior art is not high in strength, gas holes exist, and the cup wall uniformity is poor can be solved, and the molding rate of the straight-winding thin-wall hollow rotor cup and the qualified rate of products can be improved.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet DC servo motors, and relates to a thin-walled hollow rotor cup device for the motor, in particular to a method for manufacturing a straight-winding thin-walled hollow rotor cup. Background technique [0002] As a smooth armature DC motor, the coreless armature permanent magnet DC servo motor has the advantages of general permanent magnet DC motors such as linear mechanical characteristics, speed adjustment characteristics, torque-current characteristics, etc.; It has the characteristics of small moment of inertia, excellent dynamic characteristics, and small torque fluctuation (can be controlled within 2%). Therefore, this kind of motor is used in systems that require fast action, frequent starting, and forward and reverse rotation, such as car transmission. However, the rotor of this motor has no iron core, which means that the winding has no skeleton support on the rotor. It is a rotat...
