How is an electric motor made?
The coil is made of copper wire, because copper is such an excellent conductor. It is wound onto an armature. The coil becomes an electromagnet when a current flows through it. The armature supports the coil and can help make the electromagnet stronger.
How do DIY electric motors work?
This simple electric motor works by the magnetic force F = IL x B. The magnetic field at both of these spots points in the same direction. Thus, the magnetic force on the wire at opposite ends of the loop points in opposite directions, causing it to spin.
How DC motors are manufactured?
The basic dc motor manufacturing process is illustrated in Fig. 3.6. Like ac motors, the first step is producing laminations for the pole piece and armature. The armature lamination is stacked into a core, which is then assembled onto a shaft, and copper wire is inserted or wound onto the core.
How is an electric generator like an electric motor in reverse?
A generator converts mechanical energy into electrical energy, while a motor does the opposite – it converts electrical energy into mechanical energy. What’s reversed is the flow of electricity, not the activity of the machine itself.
What is the purpose of a simple electric motor?
An electric motor is a device used to convert electricity into mechanical energy —opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.
How do you make an electric motor more powerful?
We can increase the turning force (or torque) that the motor can create in three ways: either we can have a more powerful permanent magnet, or we can increase the electric current flowing through the wire, or we can make the coil so it has many “turns” (loops) of very thin wire instead of one “turn” of thick wire.
What is a simple electric motor?
A simple electric motor can be built using a coil of wire that is free to rotate between two opposite magnetic poles. A coil of wire is used with lots of turns to increase the effect of the magnetic field. A simple electric motor. Speakers contain both a permanent magnet and an electromagnet.
Can you make a motor without magnets?
Induction motors contain no permanent magnetic materials, instead they operate by inducing electrical currents in conductors in the motor’s rotor; these currents in turn give rise to a magnetic field in the rotor and thus produce torque.
Can you make the motor turn to the opposite direction?
In order to reverse the direction of an AC motor, the magnetic fields must be altered to provoke movement in the opposite direction. Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the motor to run in reverse rotation.
What is an electric motor explain with diagram?
Electric motor: A motor is a device which converts electrical energy into mechanical energy. Principle of motor: A motor works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it. Whereas the force on the side CD of the coil is in the upward direction.
What are the advantages of DC motors?
Advantages of DC Motors
- Good speed control. DC motors offer highly controllable speed.

- Free from harmonics.
What are the 3 types of DC motors?
Types of DC Motors. There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.
What are the applications of DC motor?
