As you are familiar with the principle of a DC motor or DC machine that when it is loaded either as a motor or as a generator, conductors of the rotor are carrying the current. To better understand the concept, imagine the conductors which are laying in the magnetic field which is present in the… Read More: How to Calculate Torque of DC Motor? »
What is a DC Shunt Motor? The shunt wound DC motor falls under the category of self excited DC motors, where the field windings are shunted to, or are connected in parallel to the armature winding of the motor, as its name is suggestive of. And for this reason both the armature winding and the… Read More: DC Shunt Motor – Definition & Principle »
What is an Electric Motor? An electric motor is an electromagnetic device that converts electrical energy into mechanical energy by applying the law of electromagnetic induction. The first ever electric motor was invented by William Sturgeon in 1832 which was not promoted as for commercial purposes. First commercially successful electric motor was created in 1873.… Read More: Electric Motors | Types History and Classification »
What is a VFD? As the name describes VFD or Variable Frequency Drive is motor controller that drives an electric motor by applying the varying frequency and voltage to the electric motor that are used in the case where we need to change the speed of motors depending upon the load requirements. Other names for… Read More: Variable Frequency Drive VFD Motors Principle & Equation »
Single Phase power circuits Single phase electric power or circuit refers to the distribution of alternating current electric power using a system in which all the voltages of the supply vary in corresponding exactly. Single-phase distribution is used when loads are mostly used for the purpose of lighting and heating which can also be for… Read More: Single Phase & Three Phase Power Electric Circuits & System »
Electrical functional testing is very important and critical part of any electrical project. Most of the times it is necessary to hire a third party in order to conduct the function testing of electrical systems. Big electromechanical companies are having their own testing and commissioning teams that can perform the electrical tests depending upon the… Read More: List of Functional Tests Required for Electrical Systems »
