How dose a Electric Motor Work?Electric Motor DefinitionAn electric motor is a device that converts electrical energy into mechanical energy.Motor Working PrincipleWorking principle of DC Motor mainly depends upon Fleming Left Hand rule. In a basic DC motor, an armature is placed in between magnetic poles. If the armature winding is supplied by an external DC source, current starts flowing through the armature conductors. As the conductors are carrying current inside a magnetic field, they will

What is an Electric Motor ?Electric Motor DefinitionAn electric motor is a device that converts electrical energy into mechanical energy using magnetic fields and electric currents.Core FunctioningThe main principle behind all electric motors is Faraday’s Law of induction, which describes how a force is generated from electrical and magnetic interactions.Types of Electric Motors DC Motors Synchronous Motors 3 Phase Induction Motors (a type of induction motor) Single Phase Induction Motors (a typ

What is a Slip Ring?Slip Ring DefinitionA slip ring is defined as an electromechanical device used to connect a stationary system to a rotating system to transmit power or electrical signals.Working PrincipleSlip rings have two main components: metal rings and brush contacts. The number of rings and brushes depends on the machine’s design and application.Depending on the RPM (rotations per minute), either the brushes are fixed and the rings rotate, or the rings are fixed and the brushes rotate.

What is a Rogowski Coil?Rogowski Coil DefinitionA Rogowski coil is defined as an electrical device that measures alternating current (AC) and high-speed transient or pulsed currents.Rogowski Coil CharacteristicA 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 of the coil to another end. Therefore, both terminals are at the same end of the c

What is a Centrifugal Switch?Centrifugal Switch DefinitionA centrifugal switch is an electrical component that activates based on the centrifugal force generated by a motor’s rotating shaft to control motor start-up.Operational MechanismA single-phase AC engine has a centrifugal switch inside its case, which is attached to the engine shaft. When the engine is off and motionless, the switch is closed.When the engine is switched on, the switch drives electricity to the capacitor and the extra coil
