Stator coil holder structure of generator

The utility model is a stator coil holder structure of a generator, comprising a coil holder with two ends respectively provided with two through grooves around, from the inner edges of each of which a supporting part is extended inward; more than one piece of silicon-steel sheet which is arranged on two sides of the supporting parts; a coil wound in one groove. The silicon-steel sheets are positioned in an inner diameter formed by the coils, so the generating efficiency is improved without increasing the volume of the coil holder; and the coils wound in the grooves so as to achieve the aim of increasing winding space and further increasing winding turns of the stator coil holder structure of the stator coil holder structure.
