Patent ID: 7554284

Claim:
An inductive contactless starter for single-phase AC motor, the single-phase AC motor comprising a stator composed of at least a primary winding and a secondary winding, the inductive contactless starter comprising a current mutual-inductor having at least a primary coil and a secondary coil, and a triac having a gate electrode, a first electrode, and a second electrode, wherein the gate electrode is connected to a first terminal of the secondary coil, the first electrode is connected to a second terminal of the secondary coil and a first outlet terminal of the secondary winding, and the second electrode is connected to a first power source and a first outlet terminal of the primary winding, wherein a first terminal of the primary coil is connected to the first outlet terminal of the secondary winding, and wherein the single-phase AC motor comprises a permanently operating capacitor connected between a second terminal of the primary coil and the first outlet terminal of the primary winding.
