A three-degree-of-freedom rotating motor

Abstract

The invention discloses a three-degree-of-freedom rotating motor. The three-degree-of-freedom rotating motor comprises a motor base, a rotating body, a coil set, a motor output shaft, a permanent magnet, a permanent magnet support sleeve and a motor cover, wherein the motor base and the motor cover are provided with hollow cavities; the motor output shaft is fixed on the rotating body; the coil set is mounted on the rotating body; the permanent magnet is mounted on the permanent magnet support sleeve; the outer surface of the rotating body fits the inner surface of the permanent magnet support sleeve; the rotating body can rotate in the hollow cavity of the permanent magnet support sleeve; the permanent magnet support sleeve is positioned in the hollow cavity of the motor base; the outer surface of the permanent magnet support sleeve is contacted with the inner surface of the motor base; the motor base is connected with the motor cover; one end of a lead is externally connected with positive and negative electrodes of a power supply; and the other end of the lead is connected with the coil set of the rotating body. The three-degree-of-freedom rotating motor is compact in structure, small in inertia and high in flexibility, is applied to the robot control, can reduce the robot manufacturing cost, simplifies the whole robot structure, and relieves the robot arm load.

Description

technical field [0001] The invention is a three-degree-of-freedom rotating electrical machine, which belongs to the innovative technology of the three-degree-of-freedom rotating electrical machine. Background technique [0002] For the drives that control the movement of robots, the most widely used are rotary motors and linear motors, and their structures are composed of motor bases, motor covers and internal power components. Each motor is responsible for controlling the movement of the robot in the direction of one degree of freedom, and when the load of the motor is large or the rotation angle range in the direction of the degree of freedom of rotation is small, it needs to cooperate with the role of the precision reducer. In addition, because most of the existing robot products are multi-joint, the motors and precision reducers required to drive the joints occupy a large proportion in terms of cost and weight, so the cost and dead weight are too high. In addition, in o...

In addition, because most of the existing robot products are multi-joint, and the motors and precision reducers required to drive the joints occupy a large proportion in terms of cost and weight, so the cost and dead weight are too high

In addition, in order to bear the weight of the motor and precision reducer, the structure of the robot arm must be thick enough, which further increases the cost and weight of the robot
