construction of ultrasonic motor

A large hybrid transducer type ultrasonic motor has been studied for the purpose of achieving large output torque. The goal of our research is to realize a megatorque (i.e., 1000 kgf.cm) ultrasonic motor. The key to accomplishing this goal lies in obtaining sufficient longitudinal vibration in order to control the frictional force between the rotor and the stator

design and construction of shaft-driving type piezoceramic

2004-10-1 · A new approach in design of shaft-driving type piezoceramic ultrasonic motor is proposed. The stator of motor consisted of a commercial available buzzer disk in which a piezoceramic membrane is adhered to a metal sheet. The wave propagation on the metal sheet was generated by extended-shrunk force from piezoceramic oscillation

a compact linear ultrasonic motor composed by double

A minimized linear ultrasonic motor was proposed, and two flexural bimorph vibrators were utilized to form its stator. The construction of the linear ultrasonic motor and its operation principle was introduced. Two working modes with the same local deformation distribution were chosen on the basis of Finite Element Analysis (FEA)
