Abstract: A coil block manufacturing method of winding a wire around a coil core in which a core portion is provided between a first attachment portion and a second attachment portion, includes: a first step of fixing one end of the wire; a second step of, in a state of holding the first attachment portion of the coil core by a first chuck to expose the whole core portion, winding the wire around an end of the core portion; and a third step of, in a state of holding the second attachment portion of the coil core by a second chuck to expose the whole core portion, winding the wire around the whole core portion, to form a coil portion.

Abstract: According to a nozzle winding method of causing a nozzle (41) to pass between adjacent magnetic poles (12) and rotating the nozzle (41) around the magnetic pole (12), winding is carried out until the rotating nozzle (41) interferes with wound coils (201 to 242), so that a high space factor is obtained. Thereafter, according to a cam winding method, winding is carried out in a space remaining in a slot while rotating the nozzle (41) in an area not interfering with the coils (201 to 242) in the slot, thereby achieving winding with a high space factor of coils in the entire space of the slot.
