摘要：

Split-phase capacitor motors are very useful to drive home electric appliances. The authors have studied the running characteristics of the capacitor motor in which a triac is connected in series with the motor circuit to control the applied voltage in accordance with the load conditions. In this study, the ferrite magnetic wedges have been inserted into the slot openings on the motor stator and then the experimental discussions have been developed for the wedging effect on the motor characteristics. As the result, when the ferrite wedges were inserted into the slot openings, the flux density pulsation in the air gap was decreased greatly to decrease the inner power losses, resulting in the improvements of motor efficiency and characteristics.
