AC and DC Motors
AC and DC Motors are two types of motors based on the input of the type of current. As the name suggests AC Motor uses AC Current produce mechanical energy while DC Motor produces mechanical energy from Direct Current
Difference Between AC And DC Motor
The difference between AC and DC Motor are discussed below:
|
AC Motor vs DC Motor |
|
|---|---|
|
AC Motor |
DC Motor |
|
AC motor runs on alternating current. |
DC motors operate on direct current. |
|
There is no need for conversion of current in AC motors. Like AC. |
There is no need for conversion of current in AC motors. Like AC. |
|
AC motors are used where power performance is demanded for extended periods of time. |
DC motors are used where the speed of the motor needs to be controlled externally. |
|
AC motors can be single-phase or three-phase. |
All DC motors are single phase. |
|
In an AC motor the armature does not rotate while the magnetic field keeps rotating continuously. |
In a DC motor, the armature rotates while the magnetic field rotates. |
|
Repairing AC motors is not expensive. |
DC motors are very expensive to repair. |
|
Brushes are not used in AC motor. |
Brushes are used in DC motor. |
|
AC motors have a very long life span |
DC motors do not have a very long life span. |
|
The speed of AC motors can be controlled by simply changing the frequency of the current. |
The speed of DC motors can be controlled by changing the current of the armature winding. |
DC Motor
DC motor is a machine that converts electrical energy of direct current into mechanical energy. In a DC motor, the input electrical energy is direct current which is converted into mechanical rotation.
In this article, we will learn what is DC motor, its Diagram, Construction, Working, types, and applications. We will also compare DC and AC Motors based on various parameters.
