By reducing the run time of the fans, what is the approximate savings per year?
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.
2) During an energy audit, it is discovered that a laboratory has three (3) exhaust fans serving fume hoods that are operating continuously; 24 hours a day, 365 days a year.
In discussion with the Users of the building, it is determined that the fans only need to operate from 8:00 a.m to 5:00 p.m for five (5) days a week.
Each fan motor is 1/2 horsepower, single phase with a power factor of 0.85. The nameplate on the motor lists 4.9 amps at 230 Volts.
The blended electricity rate is Php 3.01/KWh. By reducing the run time of the fans, what is the approximate savings per year?
