[Effect of the invention]

 According to the invention, the motor and gearbox combination can be manufactured in a small and / or low profile configuration. Therefore, the combination of the present invention can be used in the field of precision automatic control. As shown in FIG. 6, combination 6 includes the above two combinations. Combination 6 includes stators 61 and 64, rotors 62 and 65, and gear assemblies 63 and 66. This combination 6 has two outputs to save a lot of space.

Due to the advantages of the stator and rotor design, the high speed rotation of the rotor (eg 20000 rpm) is reduced to a low speed rotation (eg 4000 rpm) by reduction of the gearbox. Therefore, the motor can be applied to drive a low-speed device such as a blower fan or an intermediate fan (eg, a cross-flow fan or a medium-sized fan). The combination of motor and gearbox according to the present invention can be widely applied to a wide variety of devices at various speeds.
