Abstract
The present invention provides a motor with differential matching gear. This motor comprises a stator, a rotor, an externally inner gear, an internally outer gear, an output shaft, and a motor housing. The stator produces magnetic lines of force, causing the rotor to rotate at a first revolving speed. The rotor has an asymmetric wall thickness. The externally inner gear has a plurality of inner teeth. The rotor dynamically changes the axle center of the externally inner gear by moving it when rotating. The internally outer gear has a plurality of outer teeth. The inner teeth partially mesh the outer teeth when the externally inner gear rotates; and the axle center of the internally outer gear remains unchanged when the internally outer gear rotates. The output shaft is driven by the internally outer gear so that it rotates at a second revolving speed less than the first revolving speed.
