This was these kinds of a major factor, the AC induction motor took over the business in many programs. Induction motors develop the rotating magnetic field at the right stage to the rotor by transformer motion concerning the stator and also the rotor, eliminating the brushes. But there’s a consequence to this too – all of the current with the rotor must go in the stator, creating the stator bigger and requiring more copper and iron, than an equivalent brush-commutated motor. But for many applications, the extension in life expectancy is very well definitely worth the added pounds and cost, And that's why we see induction motors basically just about everywhere in stationary purposes.
