Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a low-energy-consumption, anti-demagnetization, and fast-heat-dissipating motor. Background Art

[0002] Motor demagnetization refers to the weakening or loss of magnetism in the motor's magnetic steel sheets, which can lead to reduced motor performance and affect the power and speed of electric vehicles. Causes of motor demagnetization include high temperatures, vibration, overload, and water ingress. High temperatures are a major cause of demagnetization, as motors generate significant heat during operation. If heat is not properly dissipated, the magnetism of the magnetic steel sheets will gradually weaken.

[0003] After searching the existing published patent application number: CN202321035881.1, the name of the published patent is: A heat dissipation motor, comprising: a cylinder, end covers arranged at both ends of the cylinder, a plurality of ventilation holes are opened on one side of the end cover, a fixed shaft is movably connected to the end cover, a rotor and fan blades are fixedly installed on the outer wall of the fixed shaft, the fan blades are located on one side of the rotor, and a stator and a plurality of magnets are respectively provided on the inner wall of the cylinder, and the plurality of magnets are arranged around the stator. When the fixed shaft is driven to rotate by the rotor, the fan blades are driven to rotate, causing external air to enter from the ventilation holes. The air will enter from one end cover and flow out from the other end cover, thereby taking away the heat generated by the stator winding, achieving the effect of heat dissipation, and improving the stable operation efficiency. The gauze is used to filter the gas sucked in by the rotation of the fan blades to prevent dust in the wind from entering the interior of the cylinder, avoid wear and tear, and increase the practical life.

[0004] However, the above motor only dissipates heat through the fan blades, which has a poor heat dissipation effect and affects the service life of the motor. There is room for improvement. Utility Model Content
