Abstract Starting torque and speed characteristics of a microwave motor and the speed-distance characteristic of an optical motor were investigated, In both motors, a radio-electrical transducer which had directional properties, was directly attached to a rotor coil which was placed in a permanent dc magnetic field. The directional property of the radio-electrical transducer produced self-commutation. The microwave motor was operated at 5-band frequencies and the optical motor was operated with a slide projector light. Radiation from a He-Ne gas laser was considered as another energy source. In the case of the microwave motor it was found that placing the rotor coil in the middle of the dc magnetic field produced maximum torque. This operating point did not produce maximum speed. In the optical motor, when the motor is energized by the laser instead of by collimated non-coherent light of the some amount of launched transmission energy at the some distance, the motor would produce high speed.
