Technical Field

[0001] The utility model relates to the technical field of motor components, in particular to a high torque density magnetic barrier rotor for an electrically excited salient pole synchronous motor. Background Art

[0002] A rotor is a rotating body supported by bearings, and is often the main rotating part in power machinery and working machinery. Objects that do not have their own rotating shaft, such as optical disks, can be considered a rotor when rigid connections or additional shafts are used.

[0003] The utility model with prior art publication number CN216625547U relates to a dual-stator single-rotor disc-type synchronous reluctance motor, which fully utilizes the motor's reluctance torque and eliminates rare earth permanent magnet materials. It also has the advantages of compact structure, high torque power density, high efficiency of disc permanent magnet motors and wide speed regulation range, good safety, and high cost performance of synchronous reluctance motors.

[0004] However, the above-mentioned motor still has the following problems when in use: the rotor structure of the motor is an integrated structure design, and the high-torque density magnetic barrier rotor used in the electrically excited salient-pole synchronous motor wears greatly and needs to be replaced frequently, mainly because the shaft end of the rotor is worn, and its winding is not damaged. Due to its integrated design, it often needs to be replaced as a whole, which will cause unnecessary waste of materials. Utility Model Content
