Through the design of a rectangular body and external arrangement of two ends of a coil, the contact area between a magnetic steel block and an excitation winding on the generator body is increased, self-cooling effects are enhanced, the magnetic cutting distance of the magnetic steel block becomes small, vibration energy when an electric vehicle is in a small amplitude is fully recovered, and power generation amount of the linear self-power generator can be improved.
Description
Technical field
Patent of the present invention relates to electric motor car vibrations self power generation machine field.
Background technology
Current existing straight line self power generation magnetic steel of motor sheet is wider, magnetic steel ingot and excitation winding to cut magnetic induction distance larger, as by existing solid straight line self generator, be used in electric motor car vibrations self-generating system on existing defects, defect be magnetic steel ingot and excitation winding to cut magnetic induction distance comparatively large, during little amplitude, energy output is less.
The straight line self generator of existing solid wide magnetic links, can not provide when using in electric motor car be greater than the energy that himself consumes electricity, cannot promote.
Summary of the invention
For the present invention that solves the problem is by straight line self power generation motor, magnetic links Thickness Design on axis body becomes 1.5 millimeters to 5 millimeters, by solid shafting cylinder, be designed to cuboid and by external for the two ends of coil, the weight of motor self is alleviated under same energy output, magnetic links on axis body is designed to 1.5 millimeters to 5 millimeters, when unsteadiness of wheels amplitude reaches 1.5 millimeters to 5 millimeters, just can meet the working amplitude of motor, by the external design at cuboid and coil two ends, increase the contact area of excitation winding on magnetic steel ingot and body, improve the energy output of straight line self power generation motor, and improve straight line self power generation motor from radiating effect.Little amplitude high-power from the linear permanent-magnet generator that dispels the heat, be used in straight line self power generation motor electric motor car vibrations self-generating system being compared solid wide magnetic links, the deadweight alleviating vehicle body, reduce specified vibrations distance, increase the generating of electric motor car supply electricity.Little amplitude high-power from heat radiation linear permanent-magnet generator mover upper magnetic steel block cut magnetic width 1.5 millimeters to 5 millimeters, magnetic steel ingot that height 3 millimeters to 18 millimeters, length 19 to 59 millimeters, magnetic pole number of poles are respectively inside and outside one pole, coil in motor stator and the interval width 1.5 millimeters to 5 millimeters of iron core between coil, the width of coil is 2 millimeters to 9 millimeters; The position width that magnetic cut by mover upper magnetic steel block and coil is 1.5 millimeters to 5 millimeters, magnetic steel ingot is fixed on mover, coil is fixed on stator, the shape of stator and mover is respectively the cuboid of same volume, cuboid mover is arranged between the cuboid stator of two same volumes, mover in the centre of two cuboid stators, do reciprocating generating.
Patent of the present invention adopts the external design of cuboid and coil two ends, narrow magnetic links design makes straight line self power generation motor, external coil can fully naturally dispel the heat, and deducted the weight of traditional line motor housing, improve straight line self power generation motor from radiating effect, reduce self power consumption be used in electric motor car, generating that also can be stable under the state of little amplitude, with the volume of prior art heaviness, weight, coil cannot dispel the heat, inner magnet steel high temperature easily demagnetizes, wide magnetic links is compared, little amplitude is high-power from dispelling the heat linear permanent-magnet generator, magnetic steel ingot part can not be too high and demagnetize because of temperature during straight line self power generation machine operation, stable energy output can not do not reached because vibration amplitude is little.Compared with the energy output of existing straight line self generator technology equal volume or equivalent weight motor, the high-power energy output from the linear permanent-magnet generator that dispels the heat of little amplitude is more, performance is more stable.
A coil part on linear generating machine stator is external, the mover of linear electric motors is become the cuboid of equal volume with stator design, little amplitude is high-power from dispelling the heat linear permanent-magnet generator, by comprising the magnetic steel ingot that width is 1.5 millimeters to 5 millimeters, be fixed in the mover of cuboid, mover axle and mover axle hold-down nut, fixing is arranged in mover, form the high-power subpart from heat radiation linear permanent-magnet generator of little amplitude, width is 2 millimeters and is fixed on stator interior to 9 mm coils, form the high-power stationary part from heat radiation linear permanent-magnet generator of little amplitude, in the outside of disjunct two stators, interfix with body fixed mount and engine body end cover, two end caps install linear bearing, one end end cap fills a linear bearing, other end end cap fills two linear bearings, and cuboid mover is arranged between the cuboid stator of two same volumes, and little amplitude is high-power from dispelling the heat linear permanent-magnet generator, the magnetic width of cutting of mover upper magnetic steel block is 1.5 millimeters to 5 millimeters, height 3 millimeters to 18 millimeters, length 19 millimeters to 59 millimeters, the magnetic pole number of poles of magnetic steel ingot is respectively inside and outside one pole, the coil in motor stator and between coil, the interval width of iron core is 1.5 millimeters to 5 millimeters, and the width of coil is 2 millimeters to 9 millimeters, the position width that magnetic cut by mover upper magnetic steel block and coil is 1.5 millimeters to 5 millimeters.
