Abstract

The invention belongs to the technical field of high-precision motors, and discloses a compound motor with high-precision positioning. The composite motor includes: a shell, a rough positioning component, a hollow output shaft, a precise positioning component, a power switching device and a controller. The stepper motor in the coarse positioning component is responsible for the coarse positioning of the compound motor, and the ring traveling wave ultrasonic motor in the fine positioning component is responsible for the precise positioning of the end of the compound motor. The controller realizes the power output switching between the annular traveling wave ultrasonic motor and the stepping motor. The invention effectively solves the problem of short service life of the ring-shaped traveling wave ultrasonic motor for a long period of continuous operation, and prolongs the service life of the motor while ensuring high positioning accuracy.

Description

technical field [0001] The invention relates to the technical field of mechanical design and motor control, in particular to a compound motor with high precision positioning. Background technique [0002] At present, traveling wave ultrasonic motors are widely used in precision positioning instruments. Compared with traditional motors, traveling wave ultrasonic motors have the characteristics of low-speed, high-torque output, low operating noise, and large holding torque. The macroscopic performance of large holding torque is good control of the start and stop of the motor. And the motion precision of the traveling wave ultrasonic motor can reach the nanometer level. Since the traveling wave ultrasonic motor relies on the friction between the stator and the rotor working surface to convert the linear motion or rotational motion of the rotor, it is not affected by the change of the external electromagnetic field, but the frictional motion will cause the motor to generate hea...
