Question

function and working principle of dc motor??


thnx in advance​

Answer 1

Answer:

The DC motor is the device 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”. The experienced force is called the Lorentz force.

Answer 2

Answer:

$\huge\underline\mathfrak{\pink{A}\blue{N}\purple{S}\orange{W}\red{E}\green{R}}$

The DC motor work on the principle when the current-carrying conductor is placed in a magnetic field it experiences a mechanical force.

The force is experienced from high flux density to low flux density.

Magnitude of force experienced by the armature conductor is

F = BIL NEWTON

Where

B = magnetic flux density produced by the field winding

L = Active length of the conductor

I = Magnitude of the current-carrying by the conductor

The direction of the force is determined by Fleming’s left-hand rule.

Fleming’s Left-hand Rule

When a current-carrying conductor such as a wire attached to a circuit moves placed in a magnetic field, an electric current is induced in the wire due to Faraday’s law of induction.

Fleming's left-hand rule:-

The left hand is held with the thumb, first finger and second finger mutually perpendicular to each other than

The thumb is pointed in the direction of the motion of the conductor relative to the magnetic field i.e direction of the force.

The forefinger is pointed in the direction of the magnetic field.

The middle finger represents the direction of the induced or generated current within the conductor.
