What is DC motor PPT?
DC Compound Motor: • The DC compound motor is a combination of the series motor and the shunt motor. It has a series field winding that is connected in series with the armature and a shunt field that is in parallel with the armature.
What is the basic principle of DC motor?
The basic working principle of the DC motor is that whenever a current carrying conductor places in the magnetic field, it experiences a mechanical force. Fleming’s left-hand rule and its magnitude decide the direction of this force.
What are the parts of DC motor?
What are DC Motor Parts and how they work?
- Stator. A stator is one of the DC motor parts that is, as the name suggests, a static unit containing the field windings.
- Rotor.
- Yoke.
- Poles.
- Field Windings.
- Armature Windings.
- DC Motor Commutator.
- Brushes.
What is working of DC motor?
How DC motors work. In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate. A simple DC motor uses a stationary set of magnets in the stator, and a coil of wire with a current running through it to generate an electromagnetic field aligned with the centre of the coil.
What are the two main parts of a DC motor?
DC motors include two key components: a stator and an armature. The stator is the stationary part of a motor, while the armature rotates. In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate.
What is the main function of DC motor?
A direct current (DC) motor is a type of electric machine that converts electrical energy into mechanical energy. DC motors take electrical power through direct current, and convert this energy into mechanical rotation.
What is role of commutator in DC motor?
The commutator on the DC generator converts the AC into pulsating DC. On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.

What kind of energy does a DC motor use?
DC MOTOR Electrical motor: It is a machine which convert electrical energy into mechanical energy. AC Motor: motor that runs on alternating current (AC) electricity. DC Motor: motor that runs on direct current (DC) electricity.
How is the flux of a DC motor related to armature?
In dc series motor field exciting current is equal to armature current which is nothing but a load current. Therefore at light load when saturation is not attained, flux will be proportional to the armature current and hence speed will be inversely proportional to armature current.
