What is a simple motor definition?
The simple motor built in class uses a coil that is a temporary electromagnet. This coil gets the force to help create torque from the electrical current supplied by the battery. The donut magnet used in the motor is a permanent magnet, which means it has a north and a south pole that are permanently in place.
What is a commutator in a motor?
The commutator assures that the current from the generator always flows in one direction. On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.
What does an electric motor do?
electric motor, any of a class of devices that convert electrical energy to mechanical energy, usually by employing electromagnetic phenomena. Most electric motors develop their mechanical torque by the interaction of conductors carrying current in a direction at right angles to a magnetic field.
What is electric motor very short answer?
Electric Motor is a device which converts electrical energy into mechanical energy.
What are the 2 types of motor?
There are two obvious types of electric motors as determined by input voltage: AC (Alternating Current) or DC (Direct Current). While AC motors use alternating current to power a series of wound coils, DC motors use direct current to power either carbon brushes or electrical commutation.
What is motor and its types?
There are at least a dozen different types of electric motors, but there are two main classifications: alternating current (AC) or direct current (DC). How the windings within AC and DC motors interact with each other to produce mechanical force creates further distinctions within each of these classifications.
What is the function of commutator?
The function of commutator ring in an electric motor is to reverse the direction of current flowing through the coil every time coil just passes the vertical position during a revolution. Hence as the direction of the current is reversed, the torque is changed in the direction.
What is commutator in physics?
Definition of commutator 1 : a series of bars or segments connected to the armature coils (see armature sense 2b)of a generator or motor so that rotation of the armature will in conjunction with a set of fixed brushes (see brush entry 2 sense 3) convert alternating current into direct current.
Who invented the electric motor?
Michael Faraday
Thomas DavenportWilliam SturgeonEmily Davenport
Motor/Inventors
The first surviving Faraday apparatus, dating from 1822, which demonstrates his work in magnetic rotation. Faraday used this mercury bath to transform electrical energy into mechanical energy, creating the first electric motor.
What are the types of motor?

- DC Series Motor.
- DC Shunt Motor.
- Cumulative Compound Motor.
- Three phase Synchronous Motor.
- Squirrel Cage Induction Motor.
- Double Squirrel Cage Motor.
- Slip ring Induction Motor.
- Single phase Synchronous Motor.
What is an electric motor Class 10?
Electric motor is a device that converts electrical energy to mechanical energy. Parts of a Electric Motor. Insulated Copper wire: A rectangular coil of wire ABCD. Magnet Poles: A magnet as placed above ie North Pole and South Pole.
What is principle of an electric motor Class 10?
The principle of an electric motor is based on the current-carrying conductor which produces magnetic field around it. A current-carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
