Armature – It is a rectangular coil that is placed in a uniform magnetic field. The main function of the armature is to rotate the shaft or axel to which it is attached. … The work of the split ring is to change the direction of current and which leads the rotation of the armature in the same direction.
What is the role of armature in electric motor?
In electrical engineering, an armature is the component of an electric machine which carries alternating current. … When the machine or motor is used as a motor, this EMF opposes the armature current, and the armature converts electrical power to mechanical power in the form of torque, and transfers it via the shaft.
What is the function of a armature B slip rings C brushes in an AC generator?
The function of slip ring in an AC generator is that these are the hollow rings that are connected to the ends of the armature coil. They help in rotation of the coil. Also, they provide electric contact with the brushes.
What is the use of brushes in electric motor Class 10?
Brushes are used to serve electrical contact between the stationary points and the moving surfaces. They are mainly used to transfer power from rotatory armature coils to stationary wires. They are used to reduce the damage of the motors.
What is the basic principle of electric motor?
The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
What is the function of commutator in electric motor?
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 is difference between slip ring and commutator?
Physically, a slip ring is a continuous ring, whereas a commutator is segmented. Functionally, slip rings provide a continuous transfer of power, signals, or data. … Commutators, on the other hand, are used in DC motors to reverse the polarity of current in the armature windings.
What is the use of armature?
The main role of an armature is multi purposed. The primary role is to transmit current across the field, therefore generating shaft torque within an active machine otherwise strength in a linear machine. The second role of an armature is to produce an EMF (electromotive force).
What is the function of armature coil?
5) Armature Coil: It helps the motor to run. 6) Brushes: It is a device that conducts current between stationary wires and moving parts, most commonly the rotating shaft.
What is the working of motor?
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 function of brush in motor?
IN ELECTRIC MOTOR the function of brushes is to make contact with the rotating rings and through them to supply current to the coil. function of commutator in an electric motor is to reverse the direction of current through the coil periodically.
What is the use of brush in motor?
A carbon brush is a sliding contact used to transmit electrical current from a static to a rotating part in a motor or generator, and, as regards DC machines, ensuring a spark-free commutation.
What is electric motor and its principle and working?
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.
What are the 6 parts of an electric motor?
These six components include:
- 1) The Rotor. The rotor is the moving part of your electric motor. …
- 3) The Bearings. The rotor in your electric motor is supported by bearings, which allow it to turn on its axis. …
- 4) The Windings. …
- 5) The Air Gap. …
- 6) The Commutator. …
- What Do All of These Components Have in Common?
What are the similarities and differences between electric motor and generator?
The Difference Between Electric Motor and Electric Generator in Tabular Form
|Electric Motor||Electric Generator|
|The shaft of the motor is driven by the magnetic force generated between the armature and the field.||In electric generators, the shaft is attached to the rotor and is driven by the mechanical force.|
