Disc type motor of integral cooling heat radiation structure

Abstract

The invention relates to a disc type motor of an integral cooling heat radiation structure. The disc type motor is an axial flux motor, and uses a double-stator and single-rotor structure. The disc type motor comprises an enclosure assembly, wherein a rotor assembly is used for fixing a non-driving end stator assembly and a driving end stator assembly onto the enclosure assembly; the rotor assembly is positioned between the non-driving end stator assembly and the driving end stator assembly; a rotary transformer assembly is fixed on the non-driving end stator assembly; and an outlet box assembly is directly welded onto the enclosure assembly. By using the measures that an iron core is prepared from ultra-thin silicon steel sheets so as to reduce iron consumption, magnetic steel uses an epoxy cladding material to block eddy currents so as to reduce the eddy-current loss, a stator winding uses a thin enameled wire to reduce high-frequency eddy-current copper loss and the like, end cover water channels on two sides of the disc type motor, an inner water jacket and an enclosure water channel are combined and integrally designed, so that the heat convection capacity of the motor system is improved; the disc type motor has the advantages of high overload capacity, compact structure, high power factor, great power density, wide speed adjustable range and the like, and is suitable for serving as power of pure electric vehicles and hybrid electric vehicles.

[0002] The motors used in the field of pure electric and hybrid vehicles are mostly permanent magnet synchronous motors or induction motors with radial flux.

[0003] Conventional water-cooled motors generally adopt a single cooling form such as casing water cooling or end cover water cooling, while electric and hybrid electric vehicle motors require high protection levels, the installation space in the car is small, and the heat inside the motor is relatively poor due to the thermal conductivity of the air. Sometimes only relying on the water cooling of the casing or the water cooling of the end cover to exchange heat often cannot be dissipated in time.
