Synchronous Machines

In the Synchronous Machine section, we have seen that there are two rotating magnetic fields in the airgap of … Read More

In this section, we will describe the operation of the synchronous generator. Figure 1 shows a cross-section of … Read More

The synchronous motor, like all other rotating motors, has a stator and a rotor. Figure 1 shows a … Read More

Stepper motors are close relatives of brushless DC motors. The brushless DC motor is used where continuous motion … Read More

Regardless of which type of electric machine is chosen for a particular job, efficiency is important for several … Read More

Figure 1 shows a cross-sectional view of a salient-pole synchronous machine. The armature windings are shown as concentrated … Read More

In the AC Machine article, we examined a simple permanent-magnet AC machine. That machine used a rotating armature … Read More

Figure 1 shows a simple, single-turn, permanent- magnet machine. The single-turn coil is free to rotate between two … Read More
