Ultrasonic motor |
摘要 |
Provided herein is an ultrasonic motor in which at least fluorocarbon polymer is present on the contact surface of at least either of the rotor or the stator. Since the fluorocarbon polymer provides a smooth contact surface, the ultrasonic motor generates no noise and produces a stable starting torque and holding torque. In addition, it has a long life with a minimum of wear.
