Abstract

The invention relates to a motor rotor. The motor rotor comprises a rotating shaft main body, the rotating shaft main body is provided with a conical rotor iron core and a circular rotor iron core, the side wall, away from the circular rotor iron core, of the conical rotor iron core is fixedly connected with a spring clamping seat, the side wall of the spring clamping seat is connected with a movable ring through a spring, and the inner wall of the movable ring is slidably connected with the side wall of the rotating shaft main body. The side wall of the movable ring is fixedly connected withan annular circular truncated cone, the side wall of the annular circular truncated cone is fixedly connected with a plurality of clamping columns, the clamping columns are arranged in an annular array with the axis of the annular circular truncated cone as the center, and the rotating shaft main body is fixedly sleeved with a fan brake wheel. By utilizing the combination of the conical rotor ironcore and the circular rotor iron core, a good brake limiting effect can be achieved, air gaps are reduced, the electric energy utilization rate is improved, and meanwhile, the stability of the motorduring braking can be greatly improved by utilizing the matching of the clamping columns and limiting rings.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor rotor. Background technique [0002] Electric machines generally include a stator and a rotor, the rotor being rotatably mounted to the stator. The rotor includes a shaft, a rotor core fixed to the shaft, and a commutator. The rotor core has a number of radially protruding teeth, and winding slots are formed between adjacent teeth for accommodating coil windings, and the number of teeth of the rotor is equal to the number of winding slots. In the prior art, the conical motor has a large air gap and low power utilization rate, and the conical rotor is large in size and heavy in weight, which puts great pressure on the rotating shaft, resulting in a short service life of the entire motor. [0003] The Chinese patent whose publication number is CN2585475Y discloses a conical motor, which is mainly composed of a stator, a conical rotor, a compression spring, a fan brake whee...
