Abstract
A motor and a coreless stator coil winding unit thereof are disclosed. The coreless stator coil winding unit includes an overlapping coil winding assembly and a non-overlapping coil winding assembly. The overlapping coil winding assembly includes a plurality of first coils arranged annularly and a plurality of second coils arranged annularly. The first coils and the second coils overlap with a phase difference. The non-overlapping coil winding assembly includes a plurality of third coils arranged annularly. The third coils are each located between an adjacent one of the first coils and an adjacent one of the second coils. Thus, the back electromotive force constant and torque constant of the motor have a better performance.
