Which part of the motor works for DC motor?

Where does a DC motor work?

When kept in a magnetic field, a current-carrying conductor gains torque and develops a tendency to move. In short, when electric fields and magnetic fields interact, a mechanical force arises. This is the principle on which the DC motors work.

Which part of the motor confirm that it is a DC motor?

Detailed Solution. Based on construction, the basic difference between DC & AC motor is the commutator. The commutator is only present in DC motor, which performs the commutation phenomenon.

What is the most important part of a DC motor?

The device which is used to convert DC into AC in DC motor is called commutator. Actually it is the most important part of DC motor. It is responsible to produce the unidirectional torque in DC motor.

How does a DC motor work physics?

Electric motors use the forces produced by magnetic fields to produce a turning motion. If you put a length of wire in a magnetic field and pass a DC current through it (such as from a battery), the wire will move. This is called the motor effect .

Where is electric motor used?

Electric motors are extremely important in modern-day life. They are used in vacuum cleaners, dishwashers, computer printers, fax machines, video cassette recorders, machine tools, printing presses, automobiles, subway systems, sewage treatment plants, and water pumping stations, to mention only a few applications.

How does a DC motor work class 10?

D.C. motor can be defined as a machine which converts electrical energy to mechanical energy of rotation based on the principle of magnetic effect of current. The DC motor works according to Fleming’s right hand rule.

Which part of motor surely tell us that motor is DC motor not AC motor?

Commutator will surely tell that given motor is DC motor and not an AC type. 3.

What is AC motor and how it works?

An AC motor is a kind of electric motor that uses an electromagnetic induction phenomenon. An alternating current drives this electric motor. It is a type of electric current that periodically reverses direction and changes its magnitude continuously with time.

What are the 5 parts of a DC motor?

These components are: a stator, a rotor, a yoke, poles, armature windings, field windings, commutator, and brushes.

What is the parts of a motor?

A simple motor has the following parts:

  • A power supply – mostly DC for a simple motor.
  • Field Magnet – could be a permanent magnet or an electromagnet.
  • An Armature or rotor.
  • Commutator.
  • Brushes.
  • Axle.

How do motors work?

How do motors work? Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current.

What are the parts of AC motor?

The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field.

What is the rotor in a DC motor?

The rotor contains coil windings that are powered by the DC current and the stator contains either permanent magnets or electromagnetic windings. When the motor is powered by DC current, a magnetic field is created within the stator, attracting and repelling the magnets on the rotor.
