What is an electric motor give its principle?
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.
What is the construction of an electric motor?
The electric motor construction can be done using the rotor, bearings, stator, air gap, windings, commutator, etc. The rotor in an electric motor is the moving part, and the main function of this is to rotate the shaft for generating the mechanical power.
What is the principle of an electric motor briefly explain the construction and working of an electric motor using a Labelled diagram?
Principle: An electric motor works on the principle that a current carrying conductor placed in a magnetic field experiences a force, the direction of force is given by Fleming’s left hand rule.
What is an electric motor with the help of a diagram describe the principle and working of an electric motor?
An electric motor works on the principle of magnetic effect of electric current. In an electric motor, a rectangular coil ABCD in placed between two magnets in poles N and S. … When current is passed into the coil, it produces a magnetic field around it. The two magnetic fields interact and cause the coil to rotate.
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.
How an electric motor works step by step?
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 are the types of electric motor?
Types of Electric Motors
- AC Brushless Motors. AC brushless motors are some of the most popular in motion control. …
- DC Brushed Motors. In a DC brushed motor, brush orientation on the stator determines current flow. …
- DC Brushless Motors. …
- Direct Drive. …
- Linear Motors. …
- Servo Motors. …
- Stepper Motors.
What is the role of commutator in electric 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.
Which is the device used to generate electricity?
What is the function of brushes in electric motor?
A brush or carbon brush is an electrical contact which conducts current between stationary wires and moving parts, most commonly in a rotating shaft. Typical applications include electric motors, alternators and electric generators.
What is electric motor class 10th?
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. This creates a magnetic field as shown above.
What are the special features of commercial electric motor?
Special features of commercial electric motors are:
- The coil is wound on a soft iron core; therefore, the strength of magnetic field increases.
- The coil contains large number of turns of insulated copper wire.
- A powerful electromagnet is used in place of permanent magnet.
What is motor principle?
12.2 Introduction and definition of the motor principle
The principle of the electric motor is that it converts electrical energy into kinetic energy (mechanical energy) through the interaction of the two magnetic fields.
What is the principle of electric motor What is the role of split ring in an electric motor?
Role of Split Ring in an Electric Motor
Split ring is used for reversing the direction of current in the coil. For the continuous rotation of the coil in the same direction, the current in the coil must be reversed.
What is the working principle of an electric motor explain the function of three parts of an electric motor?
It supplies power to the motor armature or field coils. Commutator: It is the rotating interface of the armature coil with a stationary circuit. Field Magnet: The magnetic field helps to produce a torque on the rotating armature coil by virtue of Fleming’s left-hand rule.
