Method for calculating alternating-current motor stator winding coil parameters

The invention relates to a method for calculating alternating-current motor stator winding coil parameters. The method comprises the following steps of: step 1, calculating the size of an insulated coil wire; step 2, calculating the section size of the end part and the interior of a coil groove and verifying residual space in the groove; step 2, calculating the section size of the end part and the interior of a coil groove and verifying residual space in the groove; step 3, creating a space geometric model of a coil; step 4, judging whether upper and lower edges of the coil need to be subjected to arc bending; step 5, calculating the axial projection length of the end part of the coil, the arc length of the bevel edge of the end part of the coil, the length of a central line of a straight-line part of the coil, the center distance of bent arcs at two ends of the straight-line part of the coil, and the mean turn of the coil; and step 6, calculating shuttle-shaped parameters of the coil. During coil section calculation, the situation of parallel winding of different wire gauges is considered, so that the design scheme of different winding wire gauges can be satisfied; and the space geometric model is adopted, so that pure formulation of a calculation process is realized, computer programming realization is convenient, and the consumption of winding wires is reduced.
