The wave forms of the drives, besides the possibility of generating additional heat, can have other direct effects in the insulation system of the electric motors. All static drive uses electronic switching devices in its reversing section. The on and off switching action produces voltage and current peaks and transients that severely damage the insulation …

The three-phase motor is made of a stator with grooves inside it, where several coils are housed perfectly isolated from the stator mass and each other, properly distributed and connected forming three distinct and symmetrical circuits called phases. These phases must be connected in triangle (Δ) or star (Υ) to a three-phase network so that …
