Inner curve motor with three-phase winding and magnetized cylinder body

Abstract

The invention discloses an inner curve motor with a three-phase winding and a magnetized cylinder body. The inner curve motor comprises a first end cover, a second end cover, a stator arranged betweenthe first end cover and the second end cover, the cylinder body rotatably hinged inside the stator, a flow distribution device and a plunger arranged on the cylinder body. The inner wall of the stator is provided with a plurality of wrapping posts which are distributed along the circumferential direction of the inner wall, the wrapping posts are wound with coils which are electrified with three-phase alternating current, the outer circumferential surface of the cylinder body is provided with a plurality of notches along the circumferential direction of the cylinder body at equal intervals, and magnetic poles are clamped in the notches. The working life of the motor can be prolonged, meanwhile, a hydraulic system and an electromagnetic system are adopted to jointly provide torque, and theoutput torque of the motor is effectively improved so as to drive a high-torque load.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an inner curve motor with a three-phase winding and a magnetized cylinder. Background technique [0002] The inner curve radial piston motor is a multi-action low-speed high-torque hydraulic motor. In the process of each revolution, each plunger reciprocates along the curved guide rail many times. It has high power per unit mass and small volume. , Hydraulic radial force balance, high efficiency and a series of advantages. However, in some occasions, the inner curve radial motor also has insufficient output torque to drive the load to rotate. Therefore, an inner curve hydraulic motor with three-phase windings and a magnetized cylinder is proposed. [0003] The patent (CN101709685A) discloses a radial plunger type multi-action inner curve hydraulic motor, which is a kind of hydraulic equipment mainly suitable for harsh working environments such as furnace fronts. It is mainly comp...
