A new design of magnetic control type motor soft starter is provided, which makes the controllable inductor connect with the stator of motor in series.

The stator lead wire of QD115 starter and the lug can be welded without flux filled, which avoids the phenomenon of strands of thin wires getting hard after welding.
The principle of the soft starter is reducing the voltage applied to the stator of the induction motor by control the triggering angle of the thyristors in order to limit the starting current surge.
