Calculate the voltage of the DC source and the stored field energy of the actuator illustrated in figure 1.1. The dimensions of the magnetic circuit proposed in shown figure 1.2. The core of the magnetic circuit is made of cast steel material whose B-H characteristics is illustrated in figure 1.3. The coil in figure 1.1 has 250 turns, and the coil resistance is 5 ohms. For a given length g=5mm, a Dc source is connected to the coil to produce a flux density of 1 Tesla in the air gap.
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.
