Abstract
Description
Technical field
[0001] The invention relates to a fast response device of an ultrasonic motor, which is suitable for the industrial field. Background technique
[0002] Ultrasonic motor is a new driver with a new principle and a new structure that has emerged in recent years. It breaks through the concept of traditional electromagnetic motors. It has no armature windings and magnetic circuits, and does not rely on electromagnetic interaction to convert energy. Instead, it uses pressure The inverse piezoelectric effect of electroceramics and ultrasonic vibration are used to obtain the driving force, which is converted into the motion of the rotor or slider through friction coupling. Compared with the traditional electromagnetic motor, it has the characteristics of small inertia, fast response, good control characteristics, low noise, self-locking when power off, not affected by magnetic field, no magnetic field itself, low speed and high torque, and can directly drive the loa...

Embodiment Construction
[0018] The present invention will be further described below in conjunction with drawings and embodiments.
[0019] Such as figure 1 , The ultrasonic motor quick response device is composed of a feeding box, an inclined pipe, a vertical pipe, a receiving box and a three-way pipe, all of which are made of transparent plexiglass. The inner diameter of the inclined pipe and the vertical pipe is 30mm, and the bracket is made of stainless steel. The angle of the inclined tube is adjustable, thereby controlling the falling speed of the black and white balls, so that the signal sensed by the photoelectric sensor is coordinated with the motor action. The ultrasonic motor moves according to the black and white ball signals sensed by the photoelectric sensor and the position of the motor at this time, and drives the dial to detect black and white balls.
[0020] Such as figure 2 , In the detection drive circuit, the forward and reverse timing of the motor is detected by the photoelec...
