Piece is made, and the outer surface of copper sheet uses Parylene plated film；The copper sheet includes that notched circular ring shape copper sheet main body and setting exist
The connector at copper sheet main body notch both ends, the copper sheet main body are set on the newel of magnetic core, and connector passes through respective side
Support rod is placed in parallel；The copper sheet for constituting armature winding is contrary with being arranged for the copper sheet for constituting secondary windings.
Above-mentioned technical proposal is further improved, 2 copper sheets, which are connected in series, constitutes a winding element, the armature winding
Including the winding element that several are connected in parallel, secondary windings includes the winding element that several are connected in parallel.
Further, the armature winding includes 3 winding elements being connected in parallel, and secondary windings includes that 4 parallel connections connect
The winding element connect.
Further, the copper sheet is in flat.
