Virtually every factory and shop has one thing in common. It doesn’t matter whether it’s the Brain Freeze Ice Cream Factory or Joe’s Garage. That one thing is a motor. Most of the time, you’ll find more than one in use. You’ll also find both AC and DC motors. But what is the difference? Is one better than the other? In this White Paper, “DC Motors Explained,” product manager Joe Kimbrell discusses what is a DC motor, DC motor characteristics, key differences between AC and DC motors as well as when to choose one over What is a DC Motorthe other.

While there are different types of DC motors, including shunt, series, compound wound or stabilized shunt, permanent magnet, and brushless, the main difference revolves around how the electromagnetic fields are generated.

This White Paper explores the maintenance needs of DC motors and also answers questions regarding proper power.
