The previous report reported on the pneumatic nutation motor which used air pressure. In this paper, we report a new type nutation motor which doesn't use air pressure, named electromagnetic nutation motor consisting of some electromagnets, a rotary bevel gear and a fixed bevel gear. Driving the electromagnets sequentially causes nutation of the rotary bevel gear, which makes the output shaft to rotate through universal joint. In this report, first, the driving principle and design of this motor are presented. Next, the prototype of electromagnetic nutation motor is fabricated and tested. The features of electromagnetic nutation motor are (1) simple structure, (2) low noise and low vibration, (3) limitless low speed operation, (4) high resolution stepping operation.
