Special motor for paper shredder

A special motor for a paper shredder comprises a motor, and an end cover and an insulating sheet which are mounted at the output end of the motor, and is characterized in that an air inlet is formed in the non-output end of the motor, and a fan mounting cavity is formed in the output end of the motor; the fan mounting cavity is provided with an air outlet, and the air outlet is communicated with an air inlet of the motor; the fan is mounted on an output shaft of the motor in the fan mounting cavity; a fan mounting cavity of the motor is sealed by an end cover, and an output shaft of the motor extends out of a center hole of the end cover. The special motor has the advantages that the output shaft of the motor of the paper shredder drives the fan to rotate while driving the paper shredding knife to operate, the size of the special motor is reduced due to the simplified and compact structure, the size of the paper shredder is further reduced, and equipment manufacturing cost is reduced. Due to the fact that the fan is arranged at the output end of the motor, air is sucked in from the non-output end of the motor when the fan operates, cold air is conveyed to the operating motor and then exhausted from the output end of the motor, the refrigerating effect is better than that of the prior art, and heat dissipation of the motor is better facilitated.
