  • Sinusoidally distributed winding method suitable for a detector winding
    Patent number: 5486731
    Abstract: A sinusoidally distributed winding method suitable for a detector winding comprises the steps of serially connecting winding groups (x) wound sequentially at one-slot intervals to form a one-phase shunt winding group (y), and constructing an n-phase shunt winding group (Z) using n of the one-phase shunt winding groups (y). An automatic winding can be performed based on the winding procedure group wound sequentially at one-slot pitch intervals.
