Multi-strategy rotating speed controllable servo motor

Abstract

The invention discloses a multi-strategy rotating speed controllable servo motor. The servo motor comprises a casing, a high-speed shaft, and first and second rotors; the casing of a multi-stage hollow barrel-shaped structure is provided with a ring of first magnetic steel and a ring of second magnetic steel separately and successively in the inner peripheral wall; the high-speed shaft penetratesthe center of a motor shaft, a hollow tube for wiring is formed in the high-speed shaft, the front end of the high-speed shaft is led out of a opening of the casing, the leading-out end is connected with a harmonic decelerator, and the tail end of the high-speed shaft is led out of a tail opening of the casing; and the first and second rotors are arranged in the body of the high-speed shaft separately and successively and are both rotationally arranged in the casing, the first magnetic steel is distributed in the periphery of the first rotor, and the second magnetic steel is distributed in theperiphery of the second rotor. The rotating speed is controlled in high precision in a manner that excitation control is carried out on the double rotors respectively, and the servo motor also has advantages including flat structure, stable output and high structure compatibility.

Description

technical field [0001] The invention relates to the technical field of servo motors, in particular to a multi-strategy controllable speed servo motor. Background technique [0002] Servo motor is an engine that controls the operation of mechanical components in a servo system. Its control speed and position accuracy are very accurate. It can convert voltage signals into torque and speed to drive the control object. In the field of service robots, servo motors are It is used to drive the driving elements at the joints of the robot to perform high-precision connecting rod movement. However, due to the constant torque characteristic of ordinary servo motors, the speed regulation range is narrow, and it is difficult to achieve the high-precision controllability required by the robot. [0003] The dual-rotor motor is a new type of motor that can achieve flexible energy transfer. Unlike traditional motors that have only one stator and one rotor, the dual-rotor motor has two mechan...

AI Technical Summary

Problems solved by technology

With the independent control of the two rotors by the input signal, the motor responds quickly and outputs kinetic energy. This structure makes the motor occupy a large space, and cannot achieve high-precision power output, and the control method is also relatively complicated. Therefore, only Used in fields that are not sensitive to motor length and control accuracy, such as industrial robots
