ULTRASONIC MOTOR

The rotor (2) of this ultrasonic motor (1) is pressed against a pair of support sections (11, 12) of the stator (3). Contact surfaces (21, 22) are respectively formed on the top parts of the support sections (11, 12) along the contour of the outer periphery (2b) of the rotor (2). Step sections (23,...

Beschreibung
Zusammenfassung:	The rotor (2) of this ultrasonic motor (1) is pressed against a pair of support sections (11, 12) of the stator (3). Contact surfaces (21, 22) are respectively formed on the top parts of the support sections (11, 12) along the contour of the outer periphery (2b) of the rotor (2). Step sections (23, 25) are formed on contact surface (21), and step sections (24, 26) are formed on the contact surface (22), enabling the contact distance between the rotor (2) and the stator (3) to be restricted. Selon l'invention, le rotor (2) du moteur ultrasonique (1) est pressé contre une paire de sections de support (11, 12) du stator (3). Des surfaces de contact (21, 22) sont formées respectivement sur les parties supérieures des sections de support (11, 12) le long du contour de la périphérie externe (2b) du rotor (2). Des sections en gradin (23, 25) sont formées sur la surface de contact (21), et les sections en gradin (24, 26) sont formées sur la surface de contact (22), permettant à la distance de contact entre le rotor (2) et le stator (3) d'être limitée.
