This guide reviews the fundamentals of AC motors for motion control and industrial automation applications. We explain what AC motors are, the history of the AC motor, where and why AC motors are used, typical AC motor applications, how to select an AC motor, AC motor safety, AC motor speed control, and more.

AC motors are generally reliable and last a long time before needing to be replaced. The only user-serviceable parts on an AC motor are the brushes and the bearings; if the internal windings burn out, your AC motor needs to be checked out p.

Choosing the right air conditioning unit is extremely important, especially if you live in an area that gets really hot during the summer months or if it's hot all year round. The following tips can help ensure that you choose the right AC.
