Q1. A three phase 440V, 15hp motor operating at full load, 90% efficiency and 80% lagging power factor is connected to the supply through a line having an impedance of 0.3+j1.0. Determine the current drawn by the motor and the supply voltage.
Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
