Abstract
In a multi-pole electric motor, the terminal pieces of same polarities are placed adjacent to each other while the terminal pieces of different polarities are placed remote from each other, and the terminal pieces of common polarities are connected by shunt tabs which can be selectively cut apart. For instance, when a four-pole electric motor is to be used as a one-speed motor, the shunt tabs connected across associated terminal pieces are not cut apart, and the terminal pieces are appropriately connected to external power lines. When the motor is to be used as a two-speed motor, the shunt tabs connected across associated terminal pieces are cut apart, and the terminal pieces are appropriately connected to external power lines. Thus, the electric motor can be readily adapted either as a one-speed motor or a two-speed motor by using standardized component parts. Furthermore, even when the motor should overheat, there would be no short-circuiting, and the reliability of the motor can be improved.
