Simplest DC Motor Ever.

Back to Briefing.

Motor

A motor is a device which converts an electrical energy into the mechanical energy. The energy

conversion process is exactly opposite to that involved in a D.C. generator. In a generator the input

mechanical energy is supplied by a prim mover while in a D.C. motor, input electrical energy is

supplied by a D.C. supply. The construction of a D.C. machine is same whether it is a motor or

a generator.

D.C Motor

A machine that converts D.C. power into mechanical power is known as a D.C. motor.

D.C. Motor principle

D.C. motor operation is based on the principle that when a current carrying conductor is placed in

a magnetic field, the conductor experiences a mechanical force. The direction of this force is given

by Fleming’s left hand rule and magnitude is given by:

F = BIl

Where,

B is the flux density in teslas (Wb/m²)

I is the current flowing through conductor in amperes

L is the length of conductor in meters.

its enough man..Don’t go crazy …..Now lets begin our simplest project..

Requirements:

Procedure:

First of all bend the metal wire (As seen in figures 13 and 14) and put it in a wood or plastic block.
Take one or two magnates and fix on wooden or plastic block.
Take the insulated wire and round up on a cylindrical pipe.
Then remove the insulation from the insulated wire ends. (Both ends)The coil isn’t wound tightly enough.
The coil should be very tight and neat.
Take the coil (in other words, Armature) and hang on with the help of conductor above the magnets (point to be noted: Magnets produce magnetic field.). As seen in figures 13 and 14. Connect the Conductors With battery.
The Motor armature will be run with high speed.
Hold one more magnet on the top of the coil. Try changing the pole of magnet, the speed will be high.
