Many of the electrical appliances around your home require a motor to operate. AC and DC are the two most popular options, and each has distinct differences. If you’re in need of electric motor repair, it’s important to understand their unique qualities, so you seek the right services. They can also play a role in which appliances you select, and below, you’ll find everything you need to know about each.

Difference Between AC & DC Motors

DC Motors

DC motors are powered from direct currents like batteries or power converters. They’re composed of a variety of parts, including bearings, gears, and shafts, giving them speed variation and superior torque. There are two types: brushed and brushless. Brushed is a time-proven motor powered by a direct current. The brushes inside can adjust the direction and speed of the motor based on their polarity. With brushless motors—a newer technology—various circuitry controls speed and direction, which can be more efficient. Common home appliances with DC motors include coffee machines, juice dispensers, printers, battery-operated toys, and computer drives.

AC Motors

AC motors generate energy with magnetic fields created by wrapped coils. They’re different from DC motors because they use an alternating current rather than direct. There are two types: synchronous and induction. Synchronous motors rotate on a frequency that matches the supply current. Speeds can be changed based on varying this frequency. Induction motors use a magnetic field through an induced current. They’re extremely efficient and long-lasting, which is why you’ll find them in home appliances like water heaters, toaster ovens, and fans.
