Piezoceramic Ultrasonic Motor Technology
- AlliedSignal Inc. Federal Manufacturing & Technologies (FM&T), Kansas City, MO (United States)
Piezoceramic ultrasonic motors (USM) operate based on the piezoelectric effect of a piezoceramic ring that is excited by electrical signals and generates a traveling surface wave. The traveling surface wave drives a rotor through a toothed stator. These motors have several distinct advantages: low profile, high torque at low speeds, quick response, insensitivity to magnetic fields, non-sparking, quiet operation and efficiency. They are well suited for aerospace and military applications requiring a high quality, high reliability motor. American production manufacturing facilities and processes for these piezo devices do not currently exist.
