What is a Motor Armature?

Motor armatures are the rotating components of electric motors that generate the magnetic field necessary for the motor to operate. They are critical components of electric motors, and the quality and performance of the motor armature significantly impact the overall performance of the motor. Electric motors can be found in many everyday devices, including fans, toothbrushes, power tools, etc.

An electric motor combines two circuits, an electrical circuit and a magnetic circuit. Let's break down the two types of circuits and how they combine to create an electric motor:

1. Electrical Circuit - an electrical circuit is a pathway through which electricity travels. The basic components of an electrical circuit are a power source like a battery and a conductive wire. 
2. Magnetic Circuit - a magnetic circuit is a pathway through which magnetic flux travels. Unlike an electrical circuit, a magnetic circuit is permanent, so it can't be switched on or off. This circuit is generated from a magnetic core's north and south poles. 

In an electric motor, an electromagnet is created. When the wire of the electrical circuit is wrapped around a non-magnetic core, it forces that core to act as a magnet. Which means a magnetic field is generated. In the case of the motor armature, the wire wrapped around in combination with the core is what causes the motor to spin.  When the electric current is turned on and passes through the wires, a torque is generated which causes the armature to move.

Applications

Motor armatures are used in various industries and applications, including:
