Description
Technical field
The utility model relates to vacuum electromagnetic motivation fields, more particularly to vacuum electromagnetic motivation.
Background technique
Vacuum electromagnetic motivation and electromagnetic driver are all the equipment for converting mechanical energy for magnetic energy and electric energy.It is to utilize difference
Interaction force between the soft magnetic bodies (electromagnet) being fixed on stator or rotor and permanent magnet (permanent magnetic steel) and formed
Rotation torque, and obtain mechanical energy.Its working principle is same, according to magnet inherent characteristic, permanent magnet can to close proximity and
The electromagnet core for belonging to magnetic conductor generates attraction, and is fixed on rotor free to rotate in one of both, and rotor exists
This is inhaled starts turning under magneticaction.When the two apart from it is nearest when magnetic force also reach maximum, but thus this magnetic force will also start to hinder
Rotor continues to rotate, i.e., embodiment is negative torque magnetic energy by magnetic energy.The high controllability for utilizing electromagnet at this time, gives electromagnet coil
It is powered, so that coil is become one block of electromagnet identical with this obstruction rotor rotation permanent magnet pole together with iron core, because of homopolarity
It mutually arranges, attraction becomes the power that repels each other at once, and rotor continues to rotate, when going to the only suction between electromagnet core and permanent magnet
Gravitation is comprehensive to be embodied when being positive torque magnetic force.It can just stop powering.Rotor is electromagnet core is hysteresis and itself and permanent magnetism
Act between iron and being continued to rotate under the comprehensive positive torque magneticaction embodied ... and so on.That is vacuum electromagnetic motivation and electricity
Magnetic perPETual motion machine be all by control, change the pole of electromagnet to, it is magnetic whether there is or not etc., allow magnetic force be always rotor persistently rotate service,
Magnetic energy will just be presented as always positive torque magnetic energy.It is all most direct magnetic energy utilization mode.
The difference of vacuum electromagnetic motivation and electromagnetic driver is:
1, electromagnetic driver: power-using body wants brush and commutator to control the stopping of electromagnet power supply, supply, allows it on rotor
Between iron core and magnet switching and converting power source with change electromagnet poles to.Friction resistance can be generated after brush and commutator contact
Power, while can also generate heat, or even generate electric spark and interfere other wireless devices, working environment is identical as air, and there are air resistances
Power and dust are harassed.There are limitations of size of gaps etc..
2, vacuum electromagnetic motivation: the magnetism as possessed by permanent magnet is fixed and invariable, and is unable to control change formation and is held
Continuous rotation torque.Therefore it can only change the magnetic force of the electromagnet as soft magnetic bodies, be changed currently, generally being used on electromagnetic driver
Carry out converting power source to device and brush to change the pole orientation of electromagnet, still, friction can be generated after brush and commutator contact
Resistance, while can also generate heat, or even generate electric spark, this, for above situation, can design one to can undoubtedly generate greatly
Vacuum electromagnetic motivation is planted to solve the above problems.
