Abstract

Variable resistance regulating device for electric motor, for actuating a sewing machine, fed by alternating current, comprising at least one variable resistance (R1 + R2) in series, a control element (0) that allows to connect in the current circuit of the motor (M) one, many or none of the partial resistors (r1-rn, r1'-rn ') being susceptible to at least one diode (D) to be connected in series in the circuit of feeding to suppress a half-alternation of alternating current (V) of feeding and reduce the speed of drag of the motor (M), with reduced heating of the interspersed partial resistances (r1-rn), characterized by the fact that the diode ( D) is mounted in series with a part (R1) of the partial resistors (r1-rn) and shunted by the rest (R2) of the partial resistors (r1'-rn '), allowing the control element (0), by successive shorting of the first part of the resistance as partial (r1-rn), obtain a regulation on a first range of powers of weak values, and also, short-circuiting successively the other partial resistances (r1'-rn '), obtain a second range of powers of higher values.
