A part-winding starter is specifically designed for which type of motor?

A part-winding starter is specifically designed for dual voltage motors. These types of motors are typically designed to operate efficiently at two different voltage levels—usually a lower starting voltage and a higher running voltage. The part-winding starter allows the motor to start using only a portion of its windings to reduce the inrush current during startup, which helps to protect the motor and associated electrical components. Once the motor reaches a certain speed, the full winding is switched into operation, enabling it to continue running at its designated higher voltage.

This method is particularly advantageous for applications requiring high starting torque while minimizing electrical stress. Dual voltage motors are commonly used in various industrial applications where they benefit from the flexibility of operating at different voltage systems, thus highlighting the importance of the part-winding starter in managing their performance during startup and operation.
