In electrical power generation, alternating current (AC) that is created by a generator has the characteristic that its amplitude and direction changes with time. To understand three-phase motors, it is useful to first understand three-phase power. A full list of related motor articles is found in the section on related articles.
To access other resources about motors, consult one of our other motor guides covering AC motors, DC motors, Induction motors, or the more general article on the types of motors. In this article, we will discuss what a three-phase motor is and describe how it operates. While there are also single-phase induction motors available, those types of induction motors are used less frequently in industrial applications but are widely used in domestic applications such as in vacuum cleaners, refrigerator compressors, and air conditioners, owing to the use of single-phase AC power in homes and offices. Three-phase motors are one example of a type of induction motor, also known as an asynchronous motor, that operates using the principals of electromagnetic induction. Three-phase motors (also annotated numerically as 3-phase motors) are widely used in industry and have become the workhorse of many mechanical and electromechanical systems because of their relative simplicity, proven reliability, and long service life.
