Electric motors turn electricity into motion by exploiting electromagnetic induction. A simple direct current (DC) motor is illustrated below. The motor features a permanent horseshoe magnet (called the stator because it’s fixed in place) and an turning coil of wire called an armature (or rotor, because it rotates).
How does electricity power a motor?
Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current.
Why does an electric motor rotate?
A coil of wire carrying a current in a magnetic field experiences a force that tends to make it rotate. This effect can be used to make an electric motor.
How does an electric motor work in simple terms?
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.
Can an electric motor run a generator to power itself?
YES, but it can only be done long term with an electric motor that is designed to also run as a generator and if the generator will be paralleled with other generation the motor will need to be a synchronous motor.
How fast does an electric motor turn?
Motor Wiring and Number of Poles
A 60 Hz power supply changes polarity 60 times per second, and a two-pole motor will spin at 3,600 rpm when connected to this source. A four-pole motor will only rotate at 1,800 rpm. For 50 Hz motors, the speed is 3,000 rpm with 2 poles, and 1,500 rpm with 4 poles.
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 the price of electric motor?

What is electric motor explain with diagram?
1) When electric is passed into the rectangular coil, magnetic field is produced around the coil. 2)The magnetic field of horse shoe type interacts with the magnetic field on the coil and causes the coil to rotate continuously.
Does Flat Iron uses an electric motor?
Flat irons are constructed with heating elements that become hot when the flat iron is plugged into an electrical source and the power switched on. Some flat irons are battery powered, in which case they heat up simply by being switched on.
What are the three basic parts of an electric motor?
Electric motor designs can vary quite a lot, though in general they have three main parts: a rotor, a stator and a commutator. These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually as long as it receives a steady flow of electric current.
What do you think is the role of the electric motor in the materials appliances?
Answer: The role of electric motor is to converts electrical energy into mechanical energy, so that it can operate the appliances.
