DC Motor or Direct Current Motor

What is DC Motor ? The electric motor operated by dc is called dc motor. This is a device that converts DC electrical energy into a mechanical energy. Principle of DC Motor When a current carrying conductor is placed in a magnetic field, it experiences a torque and has a tendency to move. In other … Read more

Losses in DC Machine

As we know “Energy neither can be created nor it can be destroyed, it can only be transferred from one form to another”. In DC machine, mechanical energy is converted into the electrical energy. During this process, the total input power is not transformed into output power. Some part of input power gets wasted in … Read more

Working or Operating Principle of DC Motor

The DC motor is of vital importance for the industry today and is equally important for engineers to look into the working principle of DC motor in details that we have discussed in this article. To understand the operating principle of DC motor we need to first look into its single loop constructional feature. The … Read more

Construction of DC Motor (Parts & Images)

A DC motor is a device that converts direct current electrical energy to mechanical energy (learn about a DC motor’s working principle). A DC motor is constructed with: A Stator A Rotor A Yoke Poles Field windings Armature windings Commutator Brushes A stator is the static part of the DC machine that houses the field … Read more

Torque Equation of DC Motor

When a DC machine is loaded either as a motor or as a generator, the rotor conductors carry current. These conductors lie in the magnetic field of the air gap. Thus each conductor experiences a force. The conductors lie near the surface of the rotor at a common radius from its center. Hence torque is … Read more
