The speed of a dc shunt motor is directly proportional to the back emf and inversely proportional to the flux per pole. DC shunt motors are very useful and important part of any motor application. The motor speed control in dc shunt motor is very crucial because it impacts the use and design of the… Read More »
To better understand the servo motor let us first see what is the meaning of term “servo”. The term servo is applicable for any system that uses a feedback mechanism in order to control the required situation. The feedback can be in the form of signals from sensors or limit switches or number of revolutions,… Read More »
As a new electrical student or a common man this questions comes in mind that why we prefer 3 phase power system. In recent years 3 phase electric wiring has become common and mostly used worldwide for power generation, power transmission, distribution and three phase engines or motors. A single-phase electric power supply is the… Read More »
A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. Stepper motor (or step motor) is in fact a brushless DC electric motor that divides… Read More »
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 »
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 »
