Construction of a Synchronous Machine - Circuit

Construction of a Synchronous Machine, i.e. alternator or motor consists of two main parts, namely the stator and the rotor. The stator is the stationary part of the machine. It carries the armature winding in which the voltage is generated. The output of the machine is taken from the stator. The rotor is the rotating part of the machine.

Machine learning - Wikipedia

Machine learning (ML) is the study of computer algorithms that improve automatically through experience and by the use of data. It is seen as a part of artificial intelligence.Machine learning algorithms build a model based on sample data, known as "training data", in order to make predictions or decisions without being explicitly programmed to do so.

How Machine Learning Works, As Explained By

Machine learning to the rescue! The same principle applies. You build a model of likely factors that might help identify what’s a cat in images, colors, shapes and so on. Then you feed in a training set of known pictures of cats and see how well the model works. The learner then makes adjustments, and the training cycle continues.

Three Phase Induction Motor: Construction and

They run at essentially constant speed from no load to full load. However, the speed is frequency-dependent and consequently, these motors are not easily adapted to speed control. We usually prefer DC motors when large speed variations are required.. Let’s understand the construction of a three-phase induction motor before learning the working principle.
