Need of Modulation in Communication System: Until the process of superimposing a low-frequency (long-wave) voice information component on a high-frequency (short-wave) carrier signal was perfected, the most widely used form…
Braking of Induction Motor: The three types of Braking of Induction Motor, namely regenerative, dynamic and counter current braking can be accomplished with induction motors also. Regenerative braking When the…
Torque Speed Characteristics of Induction Motor: From Eq. 1.27 it can be observed that the maximum torque is independent of rotor resistance. However, the slip at which the maximum torque…
Characteristics of Three Phase Induction Motor: The performance Characteristics of Three Phase Induction Motor can be deÂrived using the approximate equivalent circuit shown in Fig. 1.20(a). In the circuit The…
Characteristics of DC Motor: DC Motors are of the rotating armature type. The armature winding is a closed winding through the commutator. The armature is supplied through the brushes which…
Inductance Formula | Inductance Symbol: Inductance Formula explains that when a wire of certain length, when twisted into a coil becomes a basic inductor. If current is made to pass…
PLC Components: A PLC is a solid state device designed to perform logic functions previously accomplished by electro-magnetic relays. Basically, the PLC Components is an assembly of solid state digital…
Relays Definition: The main purpose of a PLC is to replace real world relays. A Relays Definition is basically an electro-magnetic switch. When a voltage is applied to the coil, a…
