Which description best explains a motors working principle?
A motor is an electrical machine which converts electrical energy into mechanical energy. The principle of working of a DC motor is that “whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force”.
What is Motor write the principle on which it works?
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 principle of an electric motor Brainly?
The principle of an electric motor is based on the magnetic effect of electric current. A current-carrying loop experiences a force and rotates when placed in a magnetic field. The direction of rotation of the loop is according to the Fleming’s left-hand rule.
What is Motor explain?
A dictionary describes, “a motor is a machine that converts electrical energy to mechanical energy.” In another words, the electrical energy is a “battery” and the mechanical energy is the “rotation.” To explain a motor physically, the well-known “Fleming’s left hand rule” is a good approach.
What is the principle of electromagnet?
Electromagnet works on the principle of magnetic effect of electric current. It is formed when a strong magnetic field is produced inside a solenoid to magnetise a piece of magnetic material like soft iron.
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.
What is the purpose of motor?
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 principle of generator?
Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet.15 мая 2019 г.
What is the principle of generator and motor?
The working principle of generator is based on electromagnetic induction. The shaft of an electric motor is driven by a magnetic force which is developed between the armature and field. The shaft of an electric generator is connected to the rotor which is driven by a mechanical force.
What are the principles of electric motor?
Answer. An electric motor works on the principle that when a rectangular coil is placed in a magnetic field and a current is passed through it, a force acts on the coil which rotates it continuously. Hence, electrical energy is converted into mechanical energy.5 мая 2020 г.
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.
What is the role of split ring in an electric motor Brainly?
the role of the split ring (called commutator) in an electric motor is to reverse the direction of current flowing through the motor coil after every half rotation of the coil.
What is Motor and its types?
The working principle of the electric motor mainly depends on the interaction of magnetic and electric field. The electric motor is mainly classified into two types. They are the AC motor and the DC motor. The AC motor takes alternating current as an input, whereas the DC motor takes direct current.
