Induction Versus DC Brushless Motors Tesla

Let''s move on to induction motor drives. A forerunner of the 3phase induction motor was invented by Nikola Tesla sometime before 1889. Curiously, the stators for the 3phase induction motor and the DC brushless motor are virtually identical. Both have three sets of "distributed windings" that are inserted within the stator core.

A imobilização do moinho era feita rodando o capelo para uma posição em que o vento não propulsionasse as velas, fazendo com que o mastro perdesse velocidade. Quando imobilizado, as velas eram enroladas nas varas e estas últimas presas a algum de diversos marcos dispostos em torno do moinho através de uma corda denominada cabresto.

Adjustablespeed drive Wikipedia

DC drives are DC motor speed control systems. Since the speed of a DC motor is directly proportional to armature voltage and inversely proportional to motor flux (which is a function of field current), either armature voltage or field current can be used to control speed. Several types of DC motors are described in the electric motor article

AC Motors and Generators

One of the drawbacks of this kind of AC motor is the high current which must flow through the rotating contacts. Sparking and heating at those contacts can waste energy and shorten the lifetime of the motor. In common AC motors the magnetic field is produced by an electromagnet powered by the same AC voltage as the motor coil.
