Construction of Induction Motor

The three-phase induction motor is a preferable type of motor. It is mostly used in industrial drives because it is very reasonable and vigorous, economical and reliable. It is also called asynchronous motor because it does not run at a synchronous speed. The induction motor requires very little maintenance and also it has high overloading …

Induction Motor

Induction Motor or machines are also called as Asynchronous Machine. The word Asynchronous means that the machine never runs at synchronous speed. Induction motors are mainly of two types. It can be single-phase or three-phase induction motors. A Single-phase induction motor is usually built in small size (up to 3 H.P). The three-phase induction motors …

Generator Synchronization

A stationary generator must not be connected to live Busbars because the induced EMF is zero at standstill resulting in a short circuit. The Synchronisation procedure and the equipment for checking it are the same whether one alternator is to be connected in parallel with another alternator, or an alternator is to be connected to …

Hunting in a Synchronous Motor

The phenomenon of oscillation of the rotor about its final equilibrium position is called Hunting. On the sudden application of load, the rotor search for its new equilibrium position, and this process is known as Hunting. The Hunting process occurs in a synchronous motor as well as in synchronous generators if an abrupt change in …
