While permanent magnet motors are increasingly being utilized in high performance and high power-dense drives, the induction motor is still almost universal for new electric train drives and gaining popularity in vehicular drives. This is on top of their traditional role as an industrial drive motor for pumps and fans and also their use in servos. The key to good control of these motors is accurate...
This paper reports on the study of winding asymmetries in small synchronous generators. These types of generator are commonly used in diesel generator or back-up systems and are usually no more than a few or few tens of kilowatts with two, four, or six salient poles. The three-phase winding is 120 deg pitched, but often, lap windings are not used, rather, a hybrid of concentric winding and double...
