What are the parts of a motor?
Motor Basics. No matter the type of motor, there are three basic parts: a stator, a commutator, and a rotor. Together they use electromagnetism to cause the motor to spin. As long as the motor receives steady current, the motor works.
What is the magnetic field around a motor?
Taking the wire and coiling it around a rod with electricity generates a magnetic field. The magnetic field around the rod has two poles: north and south.
How does an electric motor stator work?
The electric motor stator stays stationary during the rotation. Usually, the stator has a row of magnets. These magnets have a casing that often looks like a drum. The rotor is inserted in the stator. Usually, the rotor consists of copper wire in a coil. The coil is around the spinning axle.
What is the ring at the end of a coil called?
At the end of the coil is a metal ring called the commutator. This piece reverses the current between the rotor and the battery. This keeps the axle spinning in a single direction. By reversing the magnet’s polarity, the rotor continues spinning through repulsion and attraction.
What are brushes made of?
Other Components. Additionally, the brushes can be made of graphite. Their role is to send an electric current to the motor’s commutator. The terminals send current to spin the rotor. They are typically located where the motor and battery attached.
Why do magnets spin?
With basic magnetism like poles repel each other. Therefore, opposite poles attract each other. By surrounding the rod with numerous magnets, the rod starts to spin. What causes the spinning? The rod moving between repulsive and attractive forces at the poles.

What is the commutator in a motor?
Commutator: It is the rotating interface of the armature coil with a stationary circuit. Field Magnet: The magnetic field helps to produce a torque on the rotating armature coil by virtue of Fleming’s left-hand rule. Armature Core: Holds the armature coil in place and provides mechanical support. Armature Coil: It helps the motor to run.
Why does an electric loop move?
Once electricity flows through your simple circuit, you will notice that your loop “moves”. So why does this happen? The magnetic field of the magnets interferes with that produced due to electric current flowing in the conductor. Since the loop has become a magnet, one side of it will be attracted to the north pole of the magnet and the other to the south pole. This causes the loop to continuously rotate. This is the principle of working of electric motor.
What is a field magnet?
Field Magnet – could be a permanent magnet or an electromagnet. An Armature or rotor. Commutator. Brushes. Axle. Power Source: A simple motor usually has a DC power source. It supplies power to the motor armature or field coils. Commutator: It is the rotating interface of the armature coil with a stationary circuit.

Why is the rotor dynamic?
Why is it dynamic? Because the coil is attached with the main shaft or main axle of the motor that will rotate.
Why do electric motors have two brushes?
In a simple electric motor should be equipped with two brushes. This brush will supply current and time for the coil rotor. In addition, this component is a popular cause that causes electric motor to die. The crust attached to the surface of the brush will cause the flow of the current to be inhibited. In addition, the condition of the brush is worn because it continues to be rubbed can also inhibit the flow of obstructed flow.
How many coils does a motor have?
On a motor generally has three stator coil. This depends on the capacity of the motor itself of course. The more the number of coils, the greater the magnetism generated. This will certainly affect the speed of the motor. But for simple electric motors, generally just complement the stator using a permanent magnet.
What is synchronous motor?
