Title:
VIBRATING MOTOR
Document Type and Number:
Japanese Patent JPH06284754
Kind Code:
A
Abstract:
PURPOSE: To excite the vibration of a stator simply, especially by a piezoelectric actuation body that operates due to a horizontal piezoelectric effect, by providing a chamfered plane part for arranging the actuation body on the peripheral surface of a hollow cylindrical body. CONSTITUTION: When arranging a chamfered plane part 3 outside in a configuration where a natural mode with two rows of wave within the peripheral surface of a vibrator 1 in hollow, cylindrical body, the movement of the inward cylindrical body surface is generated due to stretching along a line in peripheral direction and an outward movement is generated due to stretching. In this case, in the case of a hollow cylinder with a uniform thickness of D, a neutral axial line is located with a gap of D/2 from the surface of the cylindrical body, so that a height H of the chamfered plane part 3 is set to H
