What is the main purpose of a single-phase motor?

• A. To provide backup power in emergencies
• B. To convert electrical energy into mechanical energy
• C. To store electrical energy
• D. To regulate electrical current

Answer: (B)

The main purpose of a single-phase motor is to convert electrical energy into mechanical energy. Single-phase motors are widely used in various applications, particularly in domestic and light commercial settings, where the availability of single-phase AC power is common. The process involves electrical energy supplied to the motor being transformed into rotational motion, which can then drive machines, appliances, and other mechanical systems. Understanding this function highlights why single-phase motors are integral to operations that require reliable mechanical output, such as fans, pumps, and small machinery. They provide the necessary torque and motion to perform tasks that would otherwise rely on more complex systems, emphasizing their role in everyday electrical applications.
