Abstract

The invention discloses a dry and wet brushless dust collector motor which comprises a fan housing, an end cover, a stator assembly, a driving plate and a protective sleeve which are arranged in sequence. The end cover comprises an inner end cover and an outer end cover; a plurality of air outlets are formed between the inner end cover and the outer end cover in the radial direction; the inner end cover and the outer end cover are provided with a first through air supply channel; the outer wall of the fan housing is sleeved with the protective sleeve; a second air supply channel is formed between the fan cover and the protective sleeve; one end of the second air supply channel is communicated with the first air supply channel, and the other end of the second air supply channel corresponds to the inlet of the fan cover. Two-inlet and two-outlet air dissipation channels in the prior art are changed into two-inlet and one-outlet air dissipation channels, and therefore the motor is compact in overall structure, small in occupied space and good in heat dissipation effect.

Description

technical field [0001] The invention relates to a motor, in particular to a wet and dry brushless vacuum cleaner motor. Background technique [0002] The wet and dry brushless vacuum cleaner motor is mainly composed of a stator, a rotor, front and rear covers and cooling fan blades. The stator is composed of a stator core and a winding on the pole shoe. Its function is to generate excitation flux, magnetic conduction and support. Front and rear covers; the rotor is composed of rotor core, shaft, armature winding and commutator. The role of connecting and fixing the stator and rotor into one body, among which the rotating shaft, the front and rear covers must have sufficient strength to prevent the armature and the cover from resonating, causing vibration and danger. Generally, there are rolling or sliding bearings in the front and rear covers . [0003] The existing wet and dry brushless vacuum cleaner motors have double diffused air passages and adopt a two-inlet and two-...
