At present, the pump motor is expected to be reduced in its size, weight and power consumptions to the idfferent flow-rates. This paper relates to such an expected motors, and moe paticularly, to those having a similar ocnstruction to the large angle hybilid type stepping motor. The motor has a salient-pole rotor and an impeller molded with all togather. We will be able to reduce the motor size andthe input power of pumps by using the new type of motors. This paepr describes the structures of the new inner/outer type motors, their prinsiple of motion and the comparison of their features.
