A DC motor or machine consists of two windings namely field winding and armature winding. The field winding is stationary and the armature winding can rotate. The field winding produces a magnetic flux in the air gap between the armature and field windings and the armature is placed in this magnetic field.
What is construction of motor?
The electric motor construction can be done using the rotor, bearings, stator, air gap, windings, commutator, etc. electric-motor-construction. Rotor. The rotor in an electric motor is the moving part, and the main function of this is to rotate the shaft for generating the mechanical power.
What is DC motor explain construction and working with diagram?
It is a machine which converts electrical energy to mechanical energy. It is based on the principle of magnetic effect of current. Construction: It essentially consists of the following parts: (a) Field magnet (NS): In common dynamo it is a horse shoe magnet but for strong field electromagnet is used.
How is a DC machine constructed?
Construction of DC Machine. The construction of the DC machine can be done using some of the essential parts like Yoke, Pole core & pole shoes, Pole coil & field coil, Armature core, Armature winding otherwise conductor, commutator, brushes & bearings. Some of the parts of the DC machine is discussed below.
What is electric motor and its construction?
Electric motor: A motor is a device which converts electrical energy into mechanical energy. Principle of motor : A motor works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it. A force acts on the coil which rotates it continuously.
What is the construction of electric motor Class 10?
It consist of 2 halves of a metallic ring. The two ends of armature coil are connected to these 2 halves of ring. Commutators reverses the direction of current in armature coil.
What is the construction 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 are the parts of DC motor?

What is the EMF equation of DC generator?
As the armature rotates, a voltage is generated in its coils. In the case of a generator, the emf of rotation is called the Generated emf or Armature emf and is denoted as Er = Eg. In the case of a motor, the emf of rotation is known as Back emf or Counter emf and represented as Er = Eb.
What are the main parts of DC machines in construction?
It mainly consists of three main parts, i.e. magnetic field system, armature and commutator and brush gear. The other parts of a DC Generator are magnetic frame and yoke, pole core and pole shoes, field or exciting coils, armature core and windings, brushes, end housings, bearings and shafts.
How does DC motor differ from DC generator in construction?
The most significant difference between DC motor and DC generator lies in the conversion mechanism. DC motor converts electrical energy into mechanical energy whereas DC generator converts mechanical energy into an electrical energy.
What are the main parts of electric motor?
No matter the type of motor, there are three basic parts: a stator, a commutator, and a rotor. Together they use electromagnetism to cause the motor to spin. As long as the motor receives steady current, the motor works.
