  • High-torque and high-precision ultrasonic motor with self-protection function and implementation mode thereof
    Patent number: 11764705
    Abstract: A high-torque and high-precision ultrasonic motor with a self-protection function and an implementation mode of the high-torque and high-precision ultrasonic motor are provided. In the device, a gasket encloses an output shaft of an ultrasonic motor body. A harmonic reducer encloses a shell of the ultrasonic motor body. A motor shaft penetrates through the ultrasonic motor body. The end, close to the motor shaft, of the ultrasonic motor body is defined as a top end, and the bottom end of the motor shaft is sequentially enclosed with an encoder support and a high-precision encoder assembly. The gasket, the harmonic reducer, the encoder support and the high-precision encoder assembly are sequentially arranged from the ultrasonic motor body to the bottom end of the motor shaft. After the ultrasonic motor body decelerates and increases torque, the motor shaft outputs rotating speed and torque.
