What is the main difference between a single-phase and a three-phase motor?

Single-phase motor runs on single-phase AC power and needs capacitors to start, while a three-phase motor uses three currents to create continuous torque and higher efficiency.

Which motor is more energy-efficient for industrial use?

Three-phase motors are more energy-efficient and deliver constant power, making them ideal for heavy industrial machinery and continuous operations.

Are single-phase motors cheaper than three-phase motors?

Yes, single-phase motors usually have a lower initial cost and simpler wiring. However, three-phase motors can be more cost-effective long-term for high-power applications.

Where are single-phase motors commonly used?

They are widely used in homes, small workshops, agriculture equipment, compressors, pumps, fans and light commercial machinery where heavy power isn’t required.

How do I choose between a single-phase and three-phase motor?

Choose based on available power supply, required horsepower, runtime, efficiency needs and budget. Small or intermittent use suits single-phase, while heavy loads need three-phase.
