Claims (1)

[Claims for Utility Model Registration] 1. A core consisting of a yoke core and a magnetic pole core fitted to the yoke core, and a first coil and a second coil arranged opposite to each other around this core. a first bobbin and a second bobbin mounted on the core; and a third coil and a fourth coil arranged around the core to be located between the first and second bobbins and wound with a third coil and a fourth coil, respectively. a third bobbin and a fourth bobbin; a first groove formed on the first bobbin and extending from the third bobbin side to the fourth bobbin side and tilting upward in the extending direction; a notch portion formed at the uppermost end of the first grooved portion of the first bobbin and located below the first grooved portion;
from the first bobbin side to the first bobbin.
a second recessed line extending toward the second bobbin and tilting upward in the extending direction thereof, and connecting the connecting wire between the first and second coils to the notch and the second grooved line. A stator for an electric motor, in which a connecting wire between the third, fourth and fourth coils is passed through the first concave portion. 2. Both the first and second grooved stripes each have a guide piece at the top thereof, and the third bobbin has a guide piece for leading out the connecting wire corresponding to the top of the second grooved strip. A utility model characterized in that the fourth bobbin has a first concave notch and a second concave notch for leading out the connecting wire corresponding to the top of the first concave strip. A stator for an electric motor according to claim 1. 3. A stake for an electric motor according to claim 1 of claim 1, wherein the first and second concave grooves are each provided with vertical pins for connecting wires. 4. Request for utility model registration characterized in that the first coil and second coil are wound in opposite directions, and the third coil and fourth coil are wound in opposite directions. A stator for an electric motor according to item 1.
