Definition: The electrical drive system is defined as the system which is use for controlling the speed, torque and direction of an electrical motor. Each electrical drive system is different from other electrical drive systems, but there are some common features associated with all electrical drive systems. Electrical Drive Systems The figure shown below represents the …
The various types of the protective relays are available for protecting the motor from faults. These relays sense the abnormal operating condition and make the circuit breaker to trip. The motors provide protection against faults in windings and associated circuits, excessive overload and short circuits, under voltages, phase unbalances and single phasing, phase reversal and …
The potential difference and electromotive force (emf) both is the form of energy. One of the major difference between the emf and potential difference is that the emf is caused by converting the other form of energy into electrical energy whereas in potential difference the electrical energy is converted into other forms of energy. Some …

Definition: The drive which uses the electric power for moving forward, such type of drive is called an electric traction drive. One of the major application of an electric drive is to transport men and materials from one place to another. The traction drives are mainly classified into two types, i.e., the single phase AC traction …
In closed loop system, the output of the system is feedback to the input. The closed loop system controls the electrical drive, and the system is self-adjusted. Feedback loops in an electrical drive may be provided to satisfy the following requirements. Enhancement of speed of torque To improve steady-state accuracy. Protection The main parts of …
The circuit diagram of the three-phase induction motors is shown in the figure below. Magnetic contactor starter essentially consists of a set of start and stop push buttons with associated contacts, overload and underload protective devices.The start push button is a momentary contact switch that is held normally open by a spring. The stop push …
Definition: The DC motor drive is a type of amplifier or power modulator that integrate between the controller and a DC motor. It takes the low current and then converts it into a high current which is appropriate for the motor. The DC motor drive also provides the high current torque, 400 % more than …
The one of the major difference between the magnetic and electric field is that the electric field induces around the static charge particle which is either negative or positive, whereas the magnetic field produces around the poles (i.e., the north and south pole) of the magnet. Some other differences between them are explained below in …
Definition: The vehicles which get powered through a self-controlled battery for converting fuel into electricity, such type of vehicles are called battery powered vehicles or electrical vehicles. The lead acid battery is mostly used for powering the vehicles because of their low cost. The various types of DC and induction motors are used in battery …
Definition: Load equalisation is the process of smoothing the fluctuating load. The fluctuate load draws heavy current from the supply during the peak interval and also cause a large voltage drop in the system due to which the equipment may get damage. In load equalisation, the energy is stored at light load, and this energy …
