Phased excitation of a piezoelectric ring produces pro-
gressive elastic oscillations (travelling waves) along its sur-
face. This wave induces rotational motion to the rotor
pressed against it. When excitation is stopped, the shaft
is held in place by friction force. By reversing electrical
excitation, the rotor turns in the opposite direction.
Unique features of the ultrasonic motor are: compact
size, low rpm without the need for gear reduction, quick
response, quiet operation, holding torque greater than
driving torque,and lack of magnetic field generation.
The ultrasonic motor / electronic driver require a ±24
VDC power supply, switches and wiring.
DESCRIPTION
The ultrasonic motor kit is intended primarily as a conve-
nient demonstration device. It consists of an ultrasonic
motor mounted to a stand, an electronic driver, and a
controller. The controller houses the electronic driver,
power supply, on-off switching,
speed control.
