The principle (not 'principal') of operation of a d.c. motor is that whenever a current-carrying conductor is placed within a magnetic field, a force acts on that conductor which is perpendicular to that field -in other words, the force acts to push the conductor out of the field. If a pivoted loop of wire is placed within the same magnetic field, the forces on opposite sides of that loop act in opposite directions to each other, and a torque is applied to that loop. If the relative directions of current and field are maintained, then the loop will continue to rotate -this is done through the use of a split-ring commutator, a type of rotary switch, which also acts to supply the rotating loop from a fixed external circuit.

What will happen if you loose a brush in a dc motor?
It stops working.
How do car generators work?
A car generator is a DC motor. If you apply power to a working DC motor, it will turn the armature and produce work. If you turn the armature of a working DC motor, it will produce power. Generators in cars were replaced during the early 1960's with alternators.
What is the dc motor?
Almost all the electro-mechanical movements we see around us are caused either by an A.C. or a DC motor. Here we will be exploring this kind of motors. This is a device that converts DC electrical energy to a mechanical energy.Principle of DC MotorThis DC or direct current motor works on the principal, when a current carrying conductor is placed in a mgnetic field, it experiences a torque and has a tendency to move. This is known as motoring action. If the direction of current in the wire is reversed, the direction of rotation also reverses. When mgnetic field and electric field interact they produce a mechanical force, and based on that the working principle of dc motor established.
What is the explanation for the working principle of gear motor?
the gear motor is normally worked by induction and DC motor the gears is the worked of change in motor function
What are advantages of swinburne's test?
we can predetemine the efficiency of a dc machines working as a motor or generator
Can you tell me The working of DC motor?
A DC motor works on the principle of Faraday's law of electromagnetic induction, i.e., when a current carrying conductor is placed in a magnetic field, it experiences a force applied on it.
What is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
What are uses of bidirectional dc motor?
6V dc motor
What is dc motor with synchoronous operation?
A synchronous motor is an ac motor that does not run on dc.
Can DC series motor work on ac and DC and why?
A dc series motor can work on dc and ac because dc motors are totally reversible.
Can a DC dynamo act as a DC motor?
Yes it can and the otherway aroud a DC motor can be used as a dynamo
How does a DC brushless motor work?
To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.
