Abstract

The invention provides a high-torque ultrasonic motor driving system based on an SoC. The system comprises an SoC controller, a first driving module, a second driving module, a first transformer, a second transformer, an ultrasonic motor and a steady-state voltage feedback circuit, wherein the output end of the SoC controller is connected with the input ends of the first driving module and the second driving module, the output end of the first driving module is connected with the input end of the first transformer, the output end of the second driving module is connected with the input end ofthe second transformer, the output ends of the first transformer and the second transformer are connected to three input ends of the ultrasonic motor, the input end of the steady-state voltage feedback circuit is connected with the ultrasonic motor, and the output ends of the steady-state voltage feedback circuit are separately connected to the first transformer and the second transformer. Thereby, the ultrasonic motor can be started smoothly and operated steadily.

Description

technical field [0001] The invention relates to the technical field of ultrasonic motor control, in particular to a high-torque ultrasonic motor drive system based on SoC. Background technique [0002] Ultrasonic motor is a new type of motor that uses the elastic vibration and frictional rotation of piezoelectric ceramics. Compared with traditional motors, ultrasonic motors have the characteristics of low speed, large torque-to-mass ratio, fast response speed, self-locking after power failure, and no electromagnetic interference. [0003] The existing ultrasonic motor drives usually use MOS tubes to directly drive the ultrasonic motor, and are driven by two phases. [0004] The existing patented technology "Ultrasonic Motor Drive Controller Based on Embedded System-Level Chip" (ZL200710134453.3) uses the module of the chip to directly generate four-way square wave signals to drive the tube to complete the DC inverter. Phase and voltage regulation functions. [0005] Anothe...
