Description
Technical field
This utility model relates to a kind of permanent-magnet speed governor, is specifically related to the permanent-magnet speed governor of a kind of fixing magnetic gap。
Background technology
Permanent-magnet speed governor is the magnetic couple speed governing by permanent magnet, soft (magnetic) that realizes motor and load connects, have no effect electrical network harmonic wave produce, reliability is high, and can work under the various adverse circumstances such as high temperature, low temperature, humidity, dirt, inflammable and explosive, voltage instability and thunder and lightning, significantly alleviate mechanical vibration, be widely used in the industries such as electric power, iron and steel, metallurgy, petrochemical industry, papermaking, municipal administration, naval vessel, irrigation and mining。And permanent-magnet speed governor conventional at present all realizes adjustment of rotational speed by adjustment air gap, the power consumption of magnetic circuit actuator is big, and there is torque-transfer capability difference, assembly difficulty height, wastes the shortcomings such as a large amount of rare earth resources。For solving the problems referred to above, patent CN2014207550169 proposes the permanent-magnet speed governor of a kind of fixing magnetic gap, and in first, second, the arrangement mode of p-m rotor is arranged side by side along driven shaft length direction, takies larger space；In addition p-m rotor and outer conductor rotor are directly adjacent to centre and do not have any protective barrier in first, second, and safety is relatively low。
Summary of the invention
For the problems referred to above, this utility model provides the permanent-magnet speed governor of a kind of a kind of fixing magnetic gap reducing magnetic circuit actuator power consumption, raising torque-transfer capability, reduction assembly difficulty, saving rare earth resources。
Current permanent-magnet speed governor be all by changing the air gap between conductor rotor and p-m rotor thus control conductor rotor cutting magnetic line number, realize what torque adjusted, owing to this mode exists a lot of drawback, this utility model is based on electromagnetic principle, new permanent-magnet speed governor is designed from keeping magnetic gap quantity constant, the change magnetic line of force to start with, by controlling the magnetic size that p-m rotor externally represents, thus reaching to change the purpose of torque。
For solving the problems referred to above, the technical scheme that this utility model is taked is: the permanent-magnet speed governor of a kind of fixing magnetic gap, including the outer conductor rotor being connected with power shaft and in the first of the concentric traverse of output shaft magnet rotor in magnet rotor and second, in described first, magnet rotor is positioned at the second magnet rotor inside circumference；Described outer conductor rotor has conductor along its inner peripheral surface is circumferentially distributed；In described first, in magnet rotor and second, magnet rotor is evenly distributed with at least one permanent magnet in permanent magnet and second in first along respective periphery circumference respectively, in first, in permanent magnet and second, permanent magnet quantity is identical, interior permanent magnet pole on each interior magnet rotor is circumferentially arranged and on same interior magnet rotor, permanent magnet sides adjacent magnetic pole is identical in adjacent two, and in first, in permanent magnet and second, the magnetic pole end face side of permanent magnet is respectively equipped with the first iron yoke and the second iron yoke；Permanent magnet pressing plate in second it is provided with between permanent magnet and conductor in second, magnet rotor is provided with for driving the magnetic circuit actuator that in first, magnet rotor magnet rotor in second rotates in first, for regulating in two the position relationship of permanent magnet magnetic pole of the same name on magnet rotor。
Described magnetic circuit actuator is for regulating in first the position relationship of permanent magnet magnetic pole of the same name in permanent magnet and second, and then changes the magnetic intensity of externally display。Speed regulator principle: produce relative motion with inner permanent magnetic rotor when conductor rotor rotates, permanent magnetic field produces eddy current in conductor rotor, eddy current produces again induced field and permanent magnetic field interaction simultaneously, the final direction driving p-m rotor edge identical with conductor rotor rotates, thus band is automatically connected in the output shaft rotation on p-m rotor and exports power。And the power exported is directly proportional to the magnetic field intensity (magnetic line of force intensity) of p-m rotor, the magnetic field intensity of p-m rotor is controlled by magnetic circuit actuator。Therefore this utility model can control the rotation of magnet rotor in second by magnetic circuit actuator and change the magnetic that first, second iron yoke externally shows, thus the change of divergence that outer conductor rotor and output shaft produce rotating speed is caused finally to realize the purpose of speed governing。Specifically regulate process: rotate magnet rotor in first by magnetic circuit actuator, when in second, in permanent magnet and first, the magnetic pole of the same name of permanent magnet is in corresponding position, first iron yoke, the second iron yoke are all magnetized to the kicker magnet of corresponding polarity, and externally display magnetic is the strongest；On the contrary, when in second, in permanent magnet and first, the synonyms pole of permanent magnet is in corresponding position, the magnetic line of force passes through smoothly through the first iron yoke, the second iron yoke, internal short-circuit, and the first iron yoke, the second iron yoke externally do not show magnetic；Different according to the anglec of rotation of magnet rotor in second, by the impact that magnetic circuit changes, the magnetic that the first iron yoke, the second iron yoke externally show changes to the strongest (or changing to the most weak from the most by force) from the most weak。This kind of mode, relative to the axial distance changing conductor rotor and p-m rotor, reduces the power consumption of magnetic circuit actuator, improves the transmission capacity of moment of torsion。
In first, magnet rotor is positioned at the second magnet rotor inside thus having saved inner space, has the second permanent magnet pressing plate to play the effect of one layer of protective barrier, it is prevented that chip, foreign material etc. throw away to outer conductor rotor between the second permanent magnet and outer rotor conductor。
Described magnetic circuit actuator includes the actuator for receiving control signal。
Described actuator can be electric operator, pneumatic actuator or hydraulic actuating mechanism。In use procedure, permanent-magnet speed governor is installed in certain control system, pressure, flow, liquid level or other control signals are controlled system and receive and process, it is then provided to actuator, controlled the rotation of magnet rotor in first by the actuator of actuator, change the first iron yoke, the second iron yoke externally shows the size of magnetic。
This utility model, owing to have employed fixing magnetic gap structure, substantially increases the area of contact of speed regulator and reduces assembly difficulty, having saved rare earth material, substantially increasing torque-transfer capability。Owing to have employed magnetic circuit adjustment structure, substantially reduce the power consumption performing governor motion the volume reducing adjustment actuating mechanism to greatest extent, thus being greatly reduced the overall volume of speed regulator, not only reduce material consumption and save installing space, bringing conveniently to in-site installation construction especially。By being arranged in second by magnet rotor in first, magnet rotor is internal thus having saved space, has the second permanent magnet pressing plate to play the effect of one layer of protective barrier, it is prevented that chip, foreign material etc. throw away to outer conductor rotor between the second permanent magnet and outer rotor conductor。
