A rotary brake loading motor

Abstract

The invention provides a rotary braking loading electromotor. The rotary braking loading electromotor comprises a front bearing pedestal, an electromotor shell, a rotor, a rotary shaft, a stator, a three-phase winding, a rear bearing pedestal, a brake, a rear cover base and a collecting ring. The front end of the electromotor shell is connected with an external speed reducer, the rear end of the electromotor shell is connected with the rear cover base, the front bearing pedestal and the rear bearing pedestal are installed at the two ends of the electromotor shell respectively, the stator is arranged in the electromotor shell, moreover, the stator and the electromotor shell are fixed into a whole, and the three-phase winding is embedded into the stator; the rotor is a squirrel-cage rotor and fixed to the rotary shaft, and the two ends of the rotary shaft are installed on the front bearing pedestal and the rear bearing pedestal; the brake is arranged on the rotary shaft and located in the rear cover base; the collecting ring is arranged on a shaft neck of the rear cover base in a sleeved mode and connected with the three-phase winding and the brake. The electromotor, the stator, the front bearing pedestal, the rear bearing pedestal and the rear cover base form a rotary outer shell of the loading electromotor, and the rotary braking loading electromotor is compact in structure, small in size, light in weight and high in dynamic balancing precision; the standard squirrel-cage rotor is adopted, so that heavy load start and short-time frequent forward and backward rotation are achieved, and reliability is high.

Description

technical field [0001] The invention relates to the field of motors, in particular to a rotary brake loading motor applied to an electric synchronous loader. Background technique [0002] In the mechanical power closed gear test device, the electric synchronous loader is used to simulate the actual working load of the tested gearbox and is a key component in the test device, and the loading motor is one of the core parts of the electric synchronous loader. Therefore, the loading motor The performance of the electric synchronous loader directly affects the loading stability, loading stability, size profile and maximum allowable operating speed of the electric synchronous loader, which also affects the performance and technical and economic indicators of the mechanical power closed gear test device. [0003] There are many types of motors, but there are few loading motors suitable for electric synchronous loaders. The loading motor has high requirements: (1) It can realize hi...
