摘要：

The "pneumatic wobble motor," a new type of pneumatic stepping motor, has been developed. A pneumatic wobble motor consists of a donut shaped wobble generator made of silicone rubber, a wobble ring made of metal, and an output shaft. The output shaft is encased in the wobble ring which the wobble generator covers. The wobble generator has six chambers and injecting air into each sequentially causes the wobble ring revolution, which makes the output shaft to rotate. In this report, first, the driving principle and design of this motor are presented. Next, its characteristics are analyzed theoretically. Two prototypes with different designs are fabricated and tested. The experimental results are promising. The features of pneumatic wobble motor are (1) big torque (more than 10 times that of conventional small-size electromagnetic motors). (2) simple structure and (3) waterproof and dustproof.
