A 10HP 1750 RPM 550V shunt motor has an armature resistance of 1.55Ω. If the armature takes 14.8A at full load. (assume brush drop 5V ) Calculate the (a) Counter EMF (b) Power developed by the motor in watts and horse power.
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.
