What is one characteristic of a repulsion-induction motor?

• A. More efficient than a split-phase motor
• B. Draws a lot of current on start-up
• C. Operates quietly during startup
• D. Is easily repairable

Answer: (B)

A repulsion-induction motor is characterized by its operation method during startup, which involves a significant inrush of current. This high starting current is necessary to develop the torque needed to overcome inertia and start the rotor moving. The design of the motor, which typically includes a repulsion-type winding that interacts with a rotating magnetic field, contributes to this behavior. While other motor types, such as split-phase motors, may have varying efficiencies or quieter startup characteristics, the repulsion-induction motor is particularly noted for the substantial current it draws when starting up. This characteristic is important for operators to consider, especially in terms of electrical supply requirements and the management of load on the power system to prevent voltage drops. Therefore, recognizing this feature is essential for understanding the operational dynamics and requirements of the repulsion-induction motor.
