High-precision drive and control integration motor

Abstract

The invention discloses a high-precision drive and control integration motor which comprises a power supply interface, wherein a load position detection sensor, a reducer, a motor, a motor rotor position detection sensor, and a debugging interface which is connected with a drive and a controller are integrated with a site bus interface, i.e. an output shaft connected with the load position detection sensor is directly connected with a load, two sides of the motor are respectively coaxially connected with the motor rotor position detection sensor and the reducer, the load position detection sensor and the load are coaxially arranged, and signals of the load position detection sensor and the motor rotor position sensor are led to the drive and the controller by shielding wires. The invention leads a system to have better impact and shock resistance property, is more suitable to the industry control environment; the load position detection sensor, the reducer, the motor, and the like are integrated; the backlash nonlinearity is effectively inhibited by a position controller, a speed controller and a current controller, and the system precision is improved.

Description

technical field [0001] The invention belongs to motor technology, in particular to a high-precision drive and control integrated motor. Background technique [0002] With the development of servo systems in the direction of high precision, high reliability, miniaturization, integration, intelligence, and networking, the demand for high-precision new drive and control integrated devices is increasing, and research has been carried out at home and abroad. [0003] Domestic research mainly solves the problem of speed regulation. Its research results include: robot integrated robust drive unit technology, which integrates sensors such as armature current, rotor position, reducer output torque, and acceleration into the drive unit (Qiu Zhicheng, Tan Dalong, Han Jianda, Wang Chaoyue, acceleration feedback control suppression Research on the vibration of harmonic drive system [J], High-Tech Communication, July 1999); the robot joint drive device is integrated, and the AC servo mot...

Problems solved by technology

Although related foreign inventions have position servo functions, they are all semi-closed-loop control methods based on motor-side position feedback, without considering the impact of the reduction mechanism on the control accuracy of the system

Moreover, the position measuring components of the motor basically use photoelectric code discs. It is generally difficult to use this kind of encoder in the occasions of strong impact and strong vibration, and it is difficult to meet the requirements of the industrial control environment.
