What is electric current?Current definitionIn electromagnetism, the amount of electricity passing through any cross section of the conductor in unit time is called the current intensity, referred to as current, the current symbol is I, the unit is amperes, referred to as "ampere".The cause of current formationA current is formed when the free charge in a conductor moves in a regular direction under the action of an electric field force.Direction of currentThe direction of positive charge directi

What is an Armature?An armature is the component of an electric machine (i.e., a motor or generator) that carries alternating current (AC). The armature conducts AC even on DC (Direct Current) machines via the commutator (which periodically reverses current direction) or due to electronic commutation (e.g., in a brushless DC motor).The armature provides housing and support to the armature winding, which interacts with the magnetic field formed in the air gap between the stator and the rotor. The

The electric motor is a device which converts electrical energy to mechanical energy. There are mainly three types of electric motor. DC Motor. Induction Motor. Synchronous Motor.All of these motors work in more or less same principle. Working of electric motor mainly depends upon the interaction of magnetic field with current.Now we will discuss the basic operating principle of electric motor one by one for better understanding the subject.Working of DC MotorWorking principle of DC Motor mainly

What is an Electric Motor?An electric motor (or electrical motor) is an electric machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding. This interaction generates a force (as per Faraday’s Law) in the form of torque which is applied to the motor’s shaft.Electric motors can be powered by direct current (DC) sources, such as batteries or rectifiers. Or by alterna

What is a Slip Ring?A slip ring is defined as an electromechanical device that is used to connect a stationary system to a rotating system. It is used in applications that require rotation while transmitting power or electrical signals.The slip ring also is known as an electrical rotary joint, rotating electrical connector, or electrical swivels. It is used in various electrical machines to improve mechanical performance and simplify the operation.If a device rotating for a fixed number of revol

What is a Rogowski Coil?The Rogowski coil is defined as an electrical device that is used to measure alternating current (AC). It is also used to measure the high-speed transient, pulsed current or sinusoidal current. The name Rogowski coil was named after the German physicist Walter Rogowski.A Rogowski coil is an evenly wounded coil with N number of turn and constant cross-section area A. There is no metal core in a Rogowski coil.The end terminal of the coil is returned through the central axis

What is a Centrifugal Switch?A centrifugal switchis an electrical switch powered by the centrifugal force created by a rotating shaft. This centrifugal force is typically provided by a gasoline engine or electric motor. Centrifugal switches are designed to activate or deactivate the rotational speed of the shaft.How do Centrifugal Switches work?A centrifugal switch is an electrical switch normally found in signal phase induction motors and split-phase induction motors.This switch is used to prov
