The magnet exciting coil can not only be arranged radially on the iron core of rotor or stator according to above-described embodiment and (press The right-hand rule, the flow direction that hot-wire coil is formed is radially), can also circumferentially it be arranged on the iron core of rotor or stator (pressing the right-hand rule, the tangential direction of the flow direction that hot-wire coil is formed along the circumferential direction or circumferentially).
In addition, as needed, shell or stator yoke itself can be covered outside stator yoke, shell is used as to use, it can on shell The devices such as setting heat dissipation and terminal box and its drive control;Rotor yoke or rotor itself can also be used as shaft use, rotor or Rotor yoke or shaft are arranged by rolling bearing and stator or stator yoke or shell rotation, the axial direction of stator or stator yoke or shell The also settable end cap in both ends;In addition, said stator, rotor, stator yoke, rotor yoke are also used interchangeably, become outer rotor rotation Electromagnetic actuator.
High-performance rotating electromagnetic actuator of the present invention also has performance advantage below:
1) due to (hot-wire coil is to permanent magnet or hot-wire coil to hot-wire coil) existing suction between adjacent rotor and stator Power has repulsion again, more preferably divides so that high-performance rotary actuator of the present invention has, closes characteristic.For being attracted, it is being attracted Initial stage, be passed through that maximum forward current mutually attracts by its big working gas gap side, small working gas gap side is mutually repelled to coil, All rotors so generate recursion and incremental effect, to improve sucting speed rapidly, reduce pickup time, when be attracted into When row arrives certain phase, disconnects the forward current in coil and being passed through reverse current to it arranges its former big working gas gap side mutually Reprimand, former work small air gap side mutually attract, to reduce sucting speed and guarantee the contact velocity of rotor in acceptable range It is interior.Rotary actuator i.e. of the present invention can allow and realize and first accelerate to slow down again during actuation, reduce pickup time, improve It is attracted performance, and this is that common rotating electromagnet is difficult to.
2) when because with same electromagnetic field action, the permanent magnetism body mass ratio dynamic iron core quality for providing identical magnetic force is wanted small and is obtained More, so the quality of the traditional moving component of the mass ratio of moving component of the invention and rotary inertia are much smaller, therefore it adds Speed, decelerability are more preferable, and are conducive to reduce the peak point current and energy consumption in coil, while being also beneficial to reduce and divide, syzygies Hit power.
3) multiple stator and rotor and corresponding (series connection) work in parallel can be set as needed in high-performance rotary actuator of the present invention The magnet exciting coil of work, compared with traditional rotary actuator, redundancy is more preferable (when the failure of one or several coils, remaining line Circle may continue to work), reliability is higher, production cost is lower, maintenance is more convenient.
To sum up, high-performance rotating electromagnetic actuator of the present invention, it is ingenious to use cylinder interior space and symmetrical structure The characteristics of, it is cross, straight using stator, rotor itself or stator yoke, rotor yoke itself as through conducting magnet core or conductive magnetic yoke The magnetic excitation circuit of stream or permanent magnetism provides channel, and working gas gap is reduced to original half, and (size of the air gap is to electromagnetic torque, effect The main indicators such as rate, dynamic property generate vital influence), the magnet exciting coil magnetic circuit of " one inhales a row " recursion setting and forever Magnet magnetic circuit constitutes force booster type alternate path, and permanent magnet and energization magnet exciting coil magnetic potential (ampere-turn) are several in stator and rotor interior zone All for participating in energy converting between mechanical, this common permanent magnetism, electrical excitation composite excitation electromagnet or actuator in be to be difficult to (because permanent magnet can be equivalent to the hollow coil being powered, permanent magnet can regard open circuit as in DC circuit magnetic loop) met simultaneously, because This, the electromagnetic torque of the present invention " single air gap " permanent-magnet structure can reach common rotating electromagnet under identical excitation magnetic potential (ampere-turn) 20 ~ 30 times or more, electric current is maintained to can be only the 5% of common rotating electromagnet when long hereinafter, it is also not necessary to maintain electric current, originally Self-sustaining (stall) when invention itself has the function of to power off or be powered long, rotational angle is big.It fundamentally preferably solves existing The long-term engineering constraints such as structure is complicated for the electromagnetic actuators such as rotating electromagnet, power output is small, volume is big, at high cost, poor reliability are answered Bottleneck problem, provides that a kind of compact-sized, simple process, output torque and rotational angle are big, self-sustaining when having long Function, the simple high-performance rotating electromagnetic actuator of control.It the composite can be widely applied to universal electromagnetic actuator, Electromagnetically-operating The industry such as mechanism (including breaker, solenoid valve, brake, clutch etc.) and civilian multiple fields.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention Equivalent change or modification made by Spirit Essence should all cover in protection scope of the present invention.
