Abstract

The invention relates to a motor, and specifically relates to a novel wheel hub motor. The novel wheel hub motor comprises a rotor, a stator, a permanent magnet, a rotary transformer and a support bearing, and is characterized in that the stator comprises an armature, an inner-side support plate and an outer-side support plate; the armature is formed by circumferentially assembling multiple detachable independent armature units, the independent armature units are composed of independent coils and independent iron cores, and the independent coils are wound on the independent iron cores; the independent armature units are installed on the outer-side support plate; the permanent magnet is fixed on the rotor; the rotary transformer is installed on the inner-side support plate; the outer-side support plate is provided with a cooling channel; the inner-side support plate and the outer-side support plate support the armature and are installed on the outer ring of the support bearing; and the rotor is installed on the inner ring of the support bearing. The novel wheel hub motor is compact in structure, reasonable in layout design, convenient to dismount and mount, convenient to maintain, small in volume, light in weight and high in strength, and can satisfy the development demands of new energy automobiles.

Description

technical field [0001] The invention relates to a drive motor for automobiles, in particular to a novel hub motor with an improved stator structure. Background technique [0002] New energy vehicles have now become a forward-looking field in the automotive industry, and the driving technology of new energy vehicles is quite different from traditional internal combustion engine vehicles, and one type of driving technology has great development prospects, which is in-wheel motor technology. The so-called in-wheel motor technology, also known as in-wheel motor technology, is characterized by the integration of power, transmission and braking devices into the wheel hub, thus greatly simplifying the mechanical parts of electric vehicles. [0003] At present, in the application fields of new energy vehicles emerging in the world, whether it is a gasoline-electric hybrid vehicle or a pure electric vehicle, two or more wheel hub drive motors with light weight and high power are requ...
