[0020] like Figures 1 to 4 shown
[0021] The bobbin 1 is in the shape of a hollow shaft. There is a coil groove 1a on the outer wall of the bobbin 1. The direction of the coil groove 1a is consistent with the axial direction of the bobbin 1. There are six permanent magnet grooves 1b on the inner wall of the bobbin 1. , six permanent magnet grooves 1b are uniformly distributed on the inner wall of the coil bobbin 1, and three terminal posts 1c are welded on the upper end of the coil bobbin 1.
[0022] like Figures 5 to 6 shown
[0023] There is a coil 2 in the coil groove 1a on the outer wall of the coil bobbin 1. The coil 2 includes two strands of enameled wire wound to form a first winding and a second winding respectively. One end of the first winding and the second winding are connected in parallel to form a common terminal, so that the entire The coil 2 has two windings and three terminals, and the three terminals of the coil 2 are respectively fixed on the three ter...
