Abstract
The invention discloses a manufacturing process of a ring-type stator coil, which comprises the steps as follows: coiling coil blank, inter-turn gelatination of linear part, coil expanding and coil shape-recovering, wherein the step of coiling coil blank is that a non-self-adhesion wire is coiled into a fusiform or trapezoidal coil blank; and the step of inter-turn gelatination of the linear part comprises the following steps: gelatination preparation, cold state finishing, heat temperature raising, thermal state finishing, exerting total pressure and cooling. The manufacturing process of the ring-type stator coil adopts the previous gelatination and posterior shaping. Since the coil is still in a flat trapezoidal or fusiform state during the gelatination of the linear part, and the end parts of the coil do not shape and is in a soft state, the gelatination of multiple coils can be executed at one time in a gelatination device, therefore, the speed of the inter-turn gelatination is accelerated, man hour is saved, and besides, labor intensity is lowered.
