[0033] Working principle: when assembling the motor and winding coil 22, first tightly attach two sets of coil 22 to the inner surface of the motor shell 24, and make the outer surface of the two sets of coil 22 symmetrical on both sides of the plug-in slot 25, then plug the heat dissipation teeth 214 on the side surface center of the coil packaging module 21 into the plug-in slot 25 on the inner surface of the motor shell 24, until the tooth-shaped clamping groove 211 on the outer surface of the heat dissipation teeth 214 is in contact with the tooth-shaped clamping block 220 on both sides of the plug-in slot 25, with the continuous plugging of the heat dissipation teeth 214 and the plug-in slot 25, the tooth-shaped clamping block 220 on both sides of the heat dissipation teeth 214 will extrude the tooth-shaped clamping block 220 on the outer surface of the plug-in column 215 to deflect the inner surface of the first limiting clamping groove 29 through the sleeve 217, until the positioning clamping groove 212 on the side surface of the coil packaging module 21 is tightly clamped with the outer surface of the coil 22.
