Abstract
A radial dual-stator permanent magnet generator is disclosed. The radial dual-stator permanent magnet generator consists of an outer stator 1, an outer stator winding 2, a rotor 3, an inner stator 4, an inner stator winding 5 and a rotary shaft 6. The rotor 3 adopts a drum-type structure made of a non-ferromagnetic material, and magnetic poles on the rotor 3 are radically arranged; two groups of stators are respectively designed in the radial interior and exterior of the rotor, the outer stator consists of the outer stator 1 and the outer stator winding 2, and the inner stator consists of the inner stator 4 and the inner stator winding 5; when the rotor 3 is driven by the rotary shaft 6 to rotate, the inner stator winding and the outer stator winding simultaneously cut magnetic force lines and both generate current with the same intensity.
Description
Technical field
The present invention relates to motor technology.Particularly relate to radial double-stator permanent magnet generator.
Background technology
Motor comprises DC generator, alternating current generator, DC motor, alternating current motor, and they are all equipment mechanical energy and electric energy mutually transformed based on electromagnetic induction principle, and they all be unable to do without coil windings.But conventional motors only make use of the magnetic energy of magnetic pole one side, the magnetic energy of another side is all shorted in the inside of rotor and has slatterned, and this is a kind of huge energy waste.
For permanent magnet generator, if there is way all to be used by the two-sided magnetic energy of rotor magnetic pole, theoretically, the efficiency of generator can improve 1 times, cannot reach this theoretical value in practice, but it is mathematical at least can obtaining significant lifting.
Summary of the invention
Radial double-stator permanent magnet generator involved in the present invention, is made up of external stator 1, external stator winding 2, rotor 3, internal stator 4, internal stator winding 5, rotating shaft 6.Rotor 3 is the core structures adopting nonferromagnetic material to make, the magnetic pole radial arrangement on rotor 3; Devise two groups of stators respectively the inside and outside of rotor radial, external stator is made up of external stator 1 and external stator winding 2, and internal stator is made up of internal stator 4 and internal stator winding 5; When rotor 3 rotates under the drive of rotating shaft 6, inside and outside stator winding is cutting magnetic line simultaneously, all produces the electric current of equality strength.
In fact radial double-stator permanent magnet generator is equivalent to 1 internal rotor permanent-magnetic generator and 1 outer rotor permanent magnet generator to combine, and its usefulness is also suitable with the generating capacity sum of these two generators.
The magnet of tradition permanent magnet generator is usually all mounted on rotor and (comprises internal rotor and external rotor), and the iron core of rotor adopts ferromagnetic material (normally silicon steel sheet) to make.So, the energy of magnet only have at most one side be utilized (in fact due to the effect of magnet short-cut path real utilize energy much smaller than this numerical value), the energy of another side produces magnet short-cut path and wastes in the ferromagnetic material of rotor.
According to the traditional internal rotor permanent-magnetic generator than same size, Energy Efficiency Ratio can promote 70 ~ 80%; And the ratio regular meeting that outer rotor permanent magnet generator promotes is larger.

embodiment: radial double-stator permanent magnet generator.
Radial double-stator permanent magnet generator is made up of inside and outside two groups of stators, and rotor is positioned at the centre of two groups of stator radial directions, is connected with prime mover of outside by rotating shaft.
The stator core that two groups of stators are made by silicon steel sheet respectively and stator winding form; Rotor adopts nonferromagnetic material to be made into tubular, can sway; Rotor is provided with the permanent magnet of magnetic pole radial arrangement, the quantity of permanent magnet is determined according to the number of poles of stator.
When rotor drags rotation by rotating shaft by prime mover, the winding of interior external stator cuts the magnetic line of force of equivalent simultaneously; If the wire diameter of winding is identical with the number of turn, the electric current of equality strength will be produced.But because the space of interior external stator is different, the quantity of winding certainly will be different, the actual electric energy exported also can difference to some extent, can be adjusted by the mode of connection.
