What is a single-phase motor?

• A. A motor that operates on a three-phase power supply
• B. A motor that operates on a single-phase power supply
• C. A motor that is designed for high torque applications
• D. A motor that connects multiple phases to operate

Answer: (B)

A single-phase motor is defined as a motor that operates on a single-phase power supply. This type of motor typically uses alternating current (AC) and is commonly used in residential and light commercial applications due to its simplicity and cost-effectiveness. Single-phase motors are ideal for applications where lower power is required, such as in household appliances like fans, small pumps, and compressors. These motors have a starting mechanism that allows them to start and operate efficiently despite the lack of a second phase to provide a rotating magnetic field, which is commonly found in three-phase motors. Understanding the operation of a single-phase motor is essential for those who work with electrical systems and machinery, as this knowledge aids in both installation and troubleshooting.
