Abstract

Improved arrangement for multiplying the speeds of electric motors in lifting mechanisms, characterized in that, being provided with a running inverter and switches for the two own speeds of the motor when the two-speed motors are concerned, the stator winding of small speed is connected and two of the three phases of the rotor winding are short-circuited, through the corresponding slip rings, with which a third speed is obtained, in the movement of rise of loads, which is equivalent to half of the nominal lower proper of the motor ; if the small speed stator winding is connected and the three phases of the rotor winding are short-circuited, by means of the corresponding slip rings and by inserting appropriate variable resistances, the lower speed of the motor itself is achieved; and if the high-speed stator winding is connected, the motor rotates at its higher speed without having to short-circuit the rotor winding.
