What is the principle of DC motor?

The DC motor is the motor which converts the direct current into the mechanical work. It works on the principle of Lorentz Law, which states that “the current carrying conductor placed in a magnetic and electric field experience a force”.

What is the principle of DC motor Class 10?

Principle : It works on the principle of motion of a current carrying conductor in a magnetic field, according to Fleming’s Left Hand Rule. It is a device which converts electrical energy into mechanical energy of rotation.

What is the working principle of AC and DC motors?

Both AC and DC motors use electrical current to produce rotating magnetic fields that, in turn, generate rotational mechanical force in the armature—located on the rotor or stator—around the shaft.

Which principle is used in motor?

An electric motor is a device used to transform electricity into mechanical energy opposite to an electric generator. They operate employing principles of electromagnetism, which determines that a force is applied when an electric current is present in a magnetic field.

What two principles does a DC motor use to run?

How Does a DC Motor Work? In the previous section, we found DC motors work on the basis of Faraday’s principle of electromagnetism and Fleming’s Left-hand rule. In this section, we show you how exactly a DC motor works and how its components cooperate to run this device.

What is the working principle of DC motor Mcq?

DC Motor Principle MCQ Question 6 Detailed Solution

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 rotation of a shaft.

What is the working principle of DC generator?

A DC generator operates on the principle of Faraday’s laws of electromagnetic induction. According to Faraday’s law, whenever a conductor is placed in a fluctuating magnetic field (or when a conductor is moved in a magnetic field) an EMF is induced in the conductor.

What is electric motor and principle?

Electric motor: An electric motor is a device which converts the electrical energy into the mechanical energy. Principle: An electric motor (dc motor) works on the principle that when an electric current is passed through a conductor placed normally in a magnetic field.

What is the principle of an electric motor by Brainly?

The principle of the electric motor is based on the fact that a current carrying conductor produces a magnetic field around it. A current carrying conductor placed perpendicular to magnetic field experiences a force.
