What is the operation principle of a DC machine?

The working principle of a DC machine is when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such as DC generator as well as DC motor.

What is DC motor explain construction and working with diagram?

The DC motor is the motor which converts the direct current into the mechanical work. It works on the principle of Lorentz Law, which states that “the current carrying conductor placed in a magnetic and electric field experience a force”. And that force is the Lorentz force.

What is the principle of DC motor Class 10?

Principle : It works on the principle of motion of a current carrying conductor in a magnetic field, according to Fleming’s Left Hand Rule. It is a device which converts electrical energy into mechanical energy of rotation.

What is the principle of operation of a direct current motor quizlet?

You just studied 9 terms! The principle of the DC motor relies on the concept of commutation. This commutator and brush connection always keep the direction of the current and the direction of the magnetic field consistent. The speed and the current to the rotor are inversely proportional.

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 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 function of the commutator in a DC motor quizlet?

When a DC machine is used as a motor, the commutator performs the function of a rotary switch and maintains the correct direction of current flow through the armature windings. An external power source supply current to the shunt field and maintain a constant magnetic field.

How can a DC motor be made to operate at its base speed?

How can a DC motor be made to operate at its base speed? By connecting full voltage to both the armature and shunt field. The resistance of the shunt field produces heat, which prevents the formation of moisture inside the motor.

What is the principle of electric motor Class 10?

An electric motor works on the principle that when a rectangular coil is placed in a magnetic field and a current is passed through it, a force acts on the coil which rotates it continuously. Hence, electrical energy is converted into mechanical energy.
