Electrical coil, has electrical conducting coil wire of primary winding, coil wire of start winding and coil wire of final winding formed by continuous winding wire, where primary winding is wound directly on coil core

摘要

The electrical coil (1) has a coil core (10) consisting of an electrical conducting material, and a primary winding (16) that exhibits an electrical conducting coil wire and surrounds the coil core. A start-winding (14) has an electrical conducting coil wire, and a final-winding (18) exhibits an electrical conducting coil wire. The coil wire of the primary winding, the coil wire of the start winding and the coil wire of the final winding are formed by a continuous winding wire. The primary winding is wound directly on the coil core.
