Dynamic Conditions of a SystemDrive: Dynamic or transient conditions occur in SystemDrive systems when the operating point changes from one steady state condition to another, following a change introduced in the system variables. These variables…
Basic Elements of Electric Drive: Basic Elements of Electric Drive- Before discussion makes clear that an electric drive system basically consists of a mechanical load to which the required mechanical motion is imparted through a…
Classification of Electric Drive: Classification of Electric Drive are normally classified into three groups, based on their development, namely group, individual and multi motor electric drives. If several groups of mechanisms or machines are organised…
Dynamic Electric: Dynamic Electric - An industrial drive system basically consists of a mechanical working equipment or load, which has to be kept in motion to turn out mechanical work, equipment to do this job,…
Starting Method of Induction Motor: Transient processes involved with the Starting Method of Induction Motor in a variable speed drive require a detailed study. The electric motor and connected load accelerates to the rated speed…
Braking of Synchronous Motor: The methods that are employed for Braking of Synchronous Motor are: Regenerative braking while operating on a variable frequency supply Rheostatic braking Plugging Regenerative braking When the motor operates as a…
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 rotor of an induction motor…
DC Motor Electric Brakes: DC Motor Electric Brakes - While operating electrical drives it is often necessary to stop the motor quickly and also reverse it. In applications like cranes or hoists the torque of…
Characteristics of Synchronous Motor: Characteristics of Synchronous Motor are constant speed motors. The speed of the motor is decided by the number of poles and frequency. Compared to an induction motor, it is very sensitive…
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 occurs changes with rotor resistance.…
