An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.
What is the purpose of an electric motor?
An electric motor is a device used to convert electrical energy into mechanical energy. Scientifically speaking, the electric motor is a unit used to convert electric power into motive energy or electrical energy into mechanical energy.
What is the basic idea of an electric motor?
The basic idea of an electric motor is really simple: you put electricity into it at one end and an axle (metal rod) rotates at the other end giving you the power to drive a machine of some kind.
What is the basic idea behind a simple electric motor How do they work?
This simple electric motor works by the magnetic force F = IL x B. The current goes around the coil so that it points one direction in one end of the loop and in the other direction at the other end of the loop. The magnetic field at both of these spots points in the same direction.
What is the working of electric motor Class 10?
Working Principle of Electric Motor
The electric motor works on the principle that when a coil is placed in the magnetic field and the current passes through it resulting in rotation of the coil.
What are the basic parts of a simple electric motor?
A simple motor has the following parts:
- A power supply – mostly DC for a simple motor.
- Field Magnet – could be a permanent magnet or an electromagnet.
- An Armature or rotor.
What is the importance of electric motor in our daily household chores?
Electric motors are extremely important in modern-day life. They are used in vacuum cleaners, dishwashers, computer printers, fax machines, video cassette recorders, machine tools, printing presses, automobiles, subway systems, sewage treatment plants, and water pumping stations, to mention only a few applications.
How do electric motors work physics?
A simple electric motor can be built using a coil of wire that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a force and moves. … When the electric current changes direction, the same end of the electromagnet becomes its south pole.
