Summary of the invention
The purpose of the utility model is a kind of radial magnetic field brushless coreless permanent magnet motor of design, and insulation stator and insulation rotor body are by injection moulding of heat-resistant antifriction engineering plastics, and it is simple to have manufacture craft; Solid and reliable, wear-resistant, energy-conservation; Cost is low, makes soon, and no short circuit phenomenon exists; Long service life, advantage safe and reliable to operation, easy to maintenance.
The utility model mainly is made up of permanent magnetism insulation rotor body and insulation stator; Permanent magnetism insulation rotor body is made up of insulation rotor body, armature spindle, yoke and permanent magnets, and the middle part is installed on the armature spindle in the insulation rotor body; Set firmly yoke on the external perisporium of insulation rotor; Set firmly several permanent magnets on the yoke periphery wall, the armature spindle both ends are coupling through bearing and end cap, and insulation rotor body and function heat-resistant antifriction macromolecular material or heat-resistant antifriction engineering plastics are processed; Insulation stator, insulation stator is processed with heat-resistant antifriction macromolecular material or heat-resistant antifriction engineering plastics, and insulation stator is the annulus bodily form; Spacing distance is provided with the wire casing of several perforations on its inwall; Set firmly stator line bag in the wire casing, the insulation stator periphery wall forms housing, and end cap is fixed on the housing.Described permanent magnetism insulation rotor body, insulation stator adopt heat-resistant antifriction macromolecular material or injection moulding of heat-resistant antifriction engineering plastics.Described yoke is an iron pipe.Described permanent magnets is a circular arc strip-shaped permanent-magnet piece.Described wire casing number and permanent magnets number are complementary.The said structure design has realized the purpose of utility model.
Insulation stator of the utility model and insulation rotor body need not to be overrided to form with silicon steel sheet; Thereby stopped traditional silicon steel sheet rotor and stator and in rotary course, also produced the magnetic damping phenomenon, motor takes electricity, influences work doing efficiency; Waste energy motor short deficiency in useful life.Insulation stator of the utility model and insulation rotor body are by injection moulding of heat-resistant antifriction engineering plastics, and it is simple to have manufacture craft, solid and reliable, wear-resistant; Energy-conservation, cost is low, makes soon, and no short circuit phenomenon exists; Long service life, advantage safe and reliable to operation, easy to maintenance.
