Embodiment approach

[0025] see figure 2 and image 3 , the motor 10 includes a stator 30 and a rotor 50 . According to an embodiment of the present invention, the motor is a brushless motor, and the stator 30 is located outside the rotor 50 . The stator 30 includes an iron core 32 and a winding 34 wound on the iron core 32 . Preferably, the iron core 32 includes a cylindrical yoke and a plurality of teeth extending radially inward from the yoke, and the winding 34 is wound on the corresponding teeth. The outer surface of the stator housing 32 is provided with a heat dissipation device 40 . The heat dissipation device 40 includes a cylindrical base 42 and a plurality of cooling fins 44 extending from the base 42 , the cooling fins 44 are distributed along the circumference of the motor at intervals, and each cooling fin 44 extends along the axial direction of the motor. The base 42 of the heat sink 40 is placed on the outer surface of the iron core 32, and the outer surface of the yoke of the...

Abstract

A motor (10) comprises a stator (30) and a rotor (50) configured to rotate inside the stator (30). A heat sink (40) has a base portion (42) disposed around and thermally connected to an outer surface of the stator (30) and a plurality of cooling fins (44) extending from the base portion (42). A centrifugal fan (70) is attached to one end of an output shaft (52) of the rotor (50), positioned such that the heat sink (40) is near an axial end of the fan (70). During operation, the centrifugal fan (70) generates an air flow over the heat sink (40), thus providing cooling for the motor (10).

Description

technical field [0001] The invention relates to a motor assembly, in particular to a motor assembly with a fan. Background technique [0002] In the existing permanent magnet motors, a heat dissipation passage is usually formed inside the motor, and a fan located in the end cover of the motor generates an airflow to flow through the passage, thereby dissipating heat from the motor. [0003] However, corresponding to high-performance motors, the internal ventilation space is getting smaller or extremely impermeable, which causes high temperature inside the motor due to poor heat dissipation, thereby affecting the life of the motor. [0004] The invention aims to provide a motor assembly with better heat dissipation effect. Contents of the invention [0005] The invention provides a motor assembly, including a motor and a fan installed on the motor shaft, the motor includes a stator and a rotor that can rotate relative to the stator, the outer surface of the stator is provi...
