An electrical machine that converts DC electrical energy into Mechanical energy. It is powered by alternating current AC. It is powered by a unidirectional direct current DC. AC motors can be single phase phase and neutral as input or three phase 3 lines of live wires as input.
DC Motors are single phase having two lines as input positive and negative. The input supply to the armature is AC, so it does not need commutation. The armature is always stationary known as Stator. DC motors can provide a more constant torque over the speed range, and generally provide faster response to load changes that AC motors.
Depending on the configuration of the coil connection series versus parallel , different performance across load value for DC motors can be obtained. Series motors exhibit higher starting torque but have a steeper drop-off in speed as the load increases. Parallel or shunt DC motors provide lower starting torque but have a flatter speed vs. AC motors suffer from efficiency issues because of the induction current loss and the slip mentioned earlier.
Brushless DC motors are more efficient than those with brushes, but the efficiency gains are primarily at the low-load or no-load areas of the motor performance curve. For a given amount of mechanical work output, AC motors are usually larger than DC motors, with brushless DC designs being the smallest.
AC motors have a long service life while DC motors require more maintenance for those designs that use brushes and commutators which feature mechanical wear.
Electronically Commutated Motors ECMs are a form of brushless DC motor that eliminates mechanical commutation and brushes in favor of electronic commutation and control, therefore improving useful life, reducing power consumption, running cooler, and providing better performance.
This article presented a brief discussion concerning the difference between AC and DC motors.

Guides Share:. Select From Over , Industrial Suppliers. Electric motors play an essential role in almost every industry.
Using the right type of motor with high-quality parts and regular servicing keeps your facility running smoothly and prevents damage to the endpoint equipment due to wear or power surges. Gainesville Industrial Electric can help your company select the right industrial electric motors and parts for your applications. Electric motors are machines that convert electrical energy—from either stored power or a direct electrical connection—into mechanical energy through the production of rotational force.
The two major types of electric motors are:. Both AC and DC motors use electrical current to produce rotating magnetic fields that, in turn, generate rotational mechanical force in the armature—located on the rotor or stator—around the shaft. While PMSM AC motors will always need a drive and tend to be slightly more expensive compared to an AC induction motor, they often are a better alternative. They have higher torque density, are much more efficient are significantly smaller and as lighter than comparable induction motors.
