🔍 Key Concepts

• Split-phase induction motor construction (starting winding vs running winding) • How direction of rotation is controlled in single-phase motors • What can and cannot be done without changing leads or windings

💭 Think About

• Think about what has to change electrically inside the motor to make the rotor start in the opposite direction. • Consider whether a plain split-phase induction motor is normally used for variable-speed control from zero to full speed. • Ask yourself which part of the motor circuit primarily determines the starting direction of rotation.

✅ Before You Answer

• Verify which winding (starting or running) is involved in setting the starting torque and direction. • Check whether reversing the motor’s direction can be done purely by external connections or must involve changing which winding leads go where. • Confirm whether a basic split-phase induction motor is known for easy, wide-range speed control.
