What are the basic parts/elements of a simple electric motor

The basic parts of an electric motor are the rotor and the stator.

This is a very simple question of a very wide subject, but we'll try to explain it the best we can. Electric motors are machines that transform electric power into mechanical power, this is the key principle. In more understandable terms, an electric motor takes voltage and current and transforms it into force and velocity.

Electric motors are very useful, specially for their simplicity and size (they are of the sort of plug-and-play devices, in comparison to other types of motors like internal combustion engines). Electric motors have also evolved over time, in the past we used to have brushed DC motors but now we mostly use brushless DC motors and AC motors.

This is important since key parts of electric motors have also changed over time, let's take a deeper look into this. The main parts of any electric motor are:

From what we just explained, there are 2 details to explain further, the commutator and the rotating magnets (or aluminium bars) :

AC, DC, electric motor, stator, rotor.

The basic parts of an electric motor are DC/AC power supply, stator, rotor, Yoke, Pole shoe, brushes and the slip ring, bearings, shaft, commutator and winding.

Further Explanation:

An Electric motor- "It is an electrical machine that converts electrical energy into mechanical energy." It works on the principle of electromagnetic induction and its working defines by Fleming’s Left-Hand Rule.

There are three types of electric motor.

1.DC Motor

2.Induction Motor

3.Synchronous Motor

It operates when there is an interaction between the magnetic field present in the motor and the electric current flowing in the winding of the coil in the motor to produce the force which enables electric motor to rotate.

Concept:

The basic parts of the electric motor are as follows:

The electric machines are basically divided into two parts.

•Stator

•Rotor

The stationary part of the electric motor is known as the stator and it consists of the main field winding and the movable part of the electric motor is called the rotor.

•DC/AC power supply- It supplies the current to the motor which enables it to work.

•Yoke- it is the outer cover of the motor which provide protection and mechanical support.

•Pole shoe- It is attached inside of the yoke and it consist of the field coils which are mounted on it.

•The brushes and the slip ring- the brushes are used in the DC motor and slip ring is used in the AC motor. The power supply is directly connected to the brushes or slip ring and through it the current able to enters into the motor. It is attached to the stator.

•Bearings-The rotor is supported by bearings and it make the rotor to turn on its axis.

•Shaft- the central long movable axis of the motor consists of the armature winding and commuter. It provides the output power to the load.

•Commutator- It is attached with the shaft and the brushes or the slip ring is touches the commutator. It is attached to the two ends of the winding and passes the current to the winding. The basic function of the commutator is to reverse the current between the rotor and the supply.

•Winding- It is attached with the shaft also called armature winding which is fixed in the armature slots. It produced the magnetic flux when current passed through the winding.

Therefore, the basic parts of an electric motor are DC/AC power supply, stator, rotor, Yoke, Pole shoe, brushes and the slip ring, bearings, shaft, commutator and winding.
