Abstract

The invention discloses an ultrasonic motor control system which comprises an upper computer, an ultrasonic motor and an ultrasonic motor controller, wherein the ultrasonic motor controller comprises a microprogrammed unit (MCU), a communication module, a clock module, a pulse width modulation (PWM) generation module, an operational amplification module, a power control module and a signal acquisition module, the clock module is used for providing a standard clock for the PWM generation module, the power control module is used for matching a signal output from the PWM generation module, the operational amplification module is used for amplifying the signal and driving the ultrasonic motor to work, the signal acquisition module is used for feeding the acquired speed signal of the ultrasonic motor back to the MCU and adjusting the output clock of the PWM generation module, and the communication module is used for data interaction with the upper computer. In the ultrasonic motor control system, the upper computer can be used for controlling the ultrasonic motor to work, the working condition of the motor can be intuitively observed by a display module, moreover, data interaction is fulfilled through a wireless communication mode, wiring is reduced, and operation is facilitated.

Description

technical field [0001] The invention relates to an ultrasonic motor control system, belonging to the field of ultrasonic motor drive control. Background technique [0002] Ultrasonic motor is a kind of motor in which piezoelectric ceramics act to cause periodic traveling waves of submicron deformation of elastic body, and then perform work through friction. Compared with traditional motors, ultrasonic motors have the characteristics of low speed, large torque / mass ratio, fast response, self-locking when power failure, nanoscale resolution, and no electromagnetic interference. [0003] Ultrasonic motors need to be driven by two quadrature phase ultrasonic frequencies provided by the ultrasonic motor driver. At present, the existing ultrasonic motor driver with all discrete components can realize the start / stop and speed regulation of the motor, but it cannot realize the communication with the host computer, and the use of discrete components makes the volume of the driver re...
