A control system for a phasing - induction motor and control method for a phasing - induction motor

摘要

The present invention relates to a control system for a phasing - induction motor, comprising: at least one electronic control circuit (6), at least one main switch (3), at least one auxiliary switch (4), at least one voltage conditioner block (5), wherein the main switch (3) are electrically connected to a main winding (21) of the phasing - induction motor (2) is joined, the auxiliary switch (4) is electrically connected to an auxiliary winding (22) of the phasing - induction motor (2) is joined, the electronic control circuit (6) electrically with the voltage conditioner block (5) via a first and a second supply connection (9, 10) is joined, the electronic control circuit (6) electrically with the main switch and the auxiliary switch (3, 4) via a first and a second control terminal (13, 14) is joined, the main switch and the auxiliary switch (3, 4) of the electronic control circuit (6) to - and are switched off in order the main winding (21) and the auxiliary winding (22) on or off, wherein the control system for a phasing - induction motor and the phasing - motor (2) is electrically connected to an ac voltage source (1) are connectable. It is provided that the voltage conditioner block (5) via a first and a second connection terminal (7, 8) in parallel with the auxiliary switch (4) which is connected to the voltage of the conditioner block (5) is capable of storing electrical energy, when the auxiliary switch (4) is switched off, whereby the voltage conditioner block (5) is adapted to the electronic control circuit (6) at least during a start-up period (tp) by means of in which the voltage conditioner block (5) of stored energy via the first and second supply connection (9, 10) to supply electrical power, which is greater than a minimum value (v_min.) an electrical voltage is, when the main - and auxiliary switch (3, 4) are switched on.
