What is a characteristic of a split phase motor?

A split phase motor is designed to operate on single-phase alternating current and is characterized by having two windings: a main winding and a start winding. This configuration allows the motor to create a phase difference necessary for starting and running. One of the common enhancements for a split phase motor is the addition of a starting capacitor. The starting capacitor improves the starting torque of the motor by creating a larger phase difference, which enhances the effectiveness of the start winding. This characteristic is particularly important for applications where higher starting torque is required, making the motor able to start under load conditions more effectively.

In contrast, a characteristic like operating on three phases does not apply to split phase motors; they are specifically designed for single-phase systems. Furthermore, the use of only one winding and being primarily suited for high-load applications do not align with what differentiates split phase motors from other types. Their typical applications involve lower loads, such as in household appliances and small machinery. Thus, the presence of a starting capacitor is a defining feature that affects performance and efficiency in these motors.
