Final answer:

Three phase motors are more powerful and efficient compared to single phase motors of equivalent horsepower. They require a three-phase power supply and have multiple windings, which result in smoother operation, reduced vibration, and higher efficiency.

Step-by-step explanation:

Motors that operate on three phases or one phase can both transform electrical energy into mechanical energy. Yet, there are some distinctions between them in terms of attributes like efficiency and power output.

When compared to single phase motors with the same horsepower, three phase motors are usually more potent and efficient. This is due to the fact that single phase motors only have one set of windings, whereas three phase motors have three sets. Three phase motors have more windings than single-phase motors, which allows for a more balanced distribution of current and leads to higher efficiency, lower vibration, and smoother operation.

Another characteristic of three phase motors is that they require a specific type of power supply called three-phase power. This power supply consists of three separate 120-degree out-of-phase alternating current waveforms. Single phase motors, on the other hand, can operate using standard single-phase power supply.
