Abstract:
1. A securing structure for motor magnets, which comprises: a casing, possessing an axle bore on one end, forming a barrel-shape outer wall around a central line defined by the axle bore, wherein two magnet seats, in a form of openings defined by two oppositely disposed inner bevels connecting with two oppositely disposed inner lateral sides, are provided bilaterally on the outer wall; wherein the casing has two symmetric protrusions disposed between the two magnet seats and parallel to the central line defined by the axle bore; a rotor, rotationally disposed inside the casing; two magnets, possessing respectively a peripheral edge defined by two oppositely disposed outer bevels connecting with two oppositely disposed outer lateral sides, wherein the outer bevels contact the inner bevels and the outer lateral sides contact the inner lateral sides, in order to make the magnet fittingly combined into the magnet seat, thereby providing magnetic force to the rotor; wherein the inner bevels are connected with as lateral side of each of the protrusions neighborly disposed; a brush fixing seat, disposed on the end opposed to the end with the axle bore; a rear cover, mounting together with the brush fixing seat coaxially on the end opposed to the end with the axle bore; and ring sleeve, mounting around the casing, while the ring sleeve is present as a barrel-shape and provided with two symmetrically disposed fixing recesses for coupling the protrusions, thereby prevent the two magnets from escaping from the magnet seat.
