Stator two layer winding structure

The utility model discloses a stator two layer winding structure, including the stator, be equipped with opening rule groove in the stator, its characterized in that: be equipped with slot insulation,upper and lower two -layer winding at opening rule inslot, its at the middle and upper levels the winding be the random wound coil, the bottom slot layer is the formed coil, in the conductor layer ofrandom wound coil and formed coil every between two -layer the brush have the organic silicon insulating varnish, guide wire arranged satisfies: every layer arrangement n circle, n are the odd number, behind the 2n layer, and 2n+1 layer n 1 the circle, 2n+2 layer n 3 the circle, 2n+3 layer n 5 the circle. Make full use of inslot space. Satisfy the full rate requirement in the high groove of control rod drive mechanism motor. Motor normal operating, and insulating material production domesticization, the the cost is reduced of great degree. 本实用新型公开了种定子双层绕组结构，包括定子，定子内设有开口嵌线槽，其特征在于：在开口嵌线槽内设有槽绝缘、上下两层绕组，其中上层绕组为散绕线圈，下层绕组为成型
