Regulation and speed change system for electric motors applicable to all universal and single-phase characterized by establishing a manual or mechanical switch with two or more positions interposed in the electrical circuit thereof, which allows an electrical resistance of adequate value to be inserted in series in the said circuit in each case whose resistance and thanks to the switch a Part previously calculated acts to reduce the speed of the motor and its entirety to produce heat energy, also allowing the addition of elements that take advantage of this energy incorporated into the carrier mechanism of the motor in question.
