PROBLEM TO BE SOLVED: To provide a motor or a stator coil set for a motor. SOLUTION: This is a concentrated winding structure where coil winding structures are combined together by separate different type columnar conductors. This is adopted in place of a well-known coil lead wire continuous winding system, and besides this sharply raises the groove occupation factor of the conductor within a coil groove by fitting the size of a coil groove to the shape of the different type columnar conductor within the coil groove, whereby this prevents the curving action when the lead wire in the coil set enters the coil groove. This is especially applicable to a motor or a generator which is of large power and is hard of multipole winding, and besides this reduces the difficulty of winding and raises the groove occupation factor and reduces the copper loss at output of a large current, in a multipole stator structure.
