摘要

Inverter for three-phase electric motors, comprising a protective box in which the contactors are housed and the upper part of which protrudes the control shaft, which at its end is fixed with a steering lever, rotating at a certain angle by two fixed stoppers arranged in the cover of said box, characterized in that said contactor members are integrated by a stationary contact disk, fixed to the cover of said box and provided with six contacts connected to each other in pairs by corresponding bridges, and a rotary contact disc, associated with said control shaft so that, following the rotational movement thereof, it can make a small axial displacement, this disc with three contacts being provided and the different contacts and the organs that cause the rotation and being arranged. the axial displacement of the rotating contact disc so that, in a position of the control , there is established direct connection between the contacts of the three phases to which respectively belong, in another position of the control, cross connection between the contacts of two of said phases, and in a third position, total disconnection.
