Description
Technical field
The present invention relates to a kind of permanent-magnet speed governor, be 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 electric power, iron and steel, metallurgy, petrochemical industry, papermaking, municipal administration, naval vessel, irrigate and the industry such as mining.And permanent-magnet speed governor conventional at present all realizes adjustment of rotational speed by adjusting air gap, the power consumption of magnetic circuit actuator is big, and has that torque-transfer capability is poor, assembly difficulty height, wastes the shortcomings such as a large amount of rare earth resources.
Summary of the invention
For the problems referred to above, the present invention 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 the air gap by changing 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, the present invention 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 reach to change the purpose of torque.
For solving the problems referred to above, the technical scheme that the present invention takes is: the permanent-magnet speed governor of a kind of fixing magnetic gap, including the outer conductor rotor being connected with driving shaft and through driven shaft concentric pass first in magnet rotor in magnet rotor and second, 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 outer circumference surface 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 permanent magnet sides adjacent magnetic pole is different in adjacent two on same interior magnet rotor, 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；It is provided with on magnet rotor in first and drives the magnetic circuit actuator that in first, magnet rotor magnet rotor in second rotates, the position relationship of interior permanent magnet magnetic pole of the same name on magnet rotor in regulation two.
Described magnetic circuit actuator is for regulation the first permanent magnet and the position relationship of the second permanent magnet magnetic pole of the same name, 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 the driven shaft that band is automatically connected on p-m rotor rotates 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 can control the rotation of magnet rotor in second by magnetic circuit actuator in the present invention and change the magnetic that first, second iron yoke externally shows, thus the change of divergence causing outer conductor rotor and driven shaft to produce rotating speed finally realizes the purpose of speed governing.Specifically regulate process: being rotated by magnetic circuit actuator can magnet rotor in first, 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 the most do not show magnetic；Different according to the anglec of rotation of magnet rotor in second, changed by magnetic circuit and affected, the magnetic that the first iron yoke, the second iron yoke externally show changes to the strongest (or the most weak from changing to the most by force) from the most weak.This kind of mode, for changing the conductor rotor axial distance with p-m rotor, reduces the power consumption of magnetic circuit actuator, improves the transmission capacity of moment of torsion.
Described magnetic circuit actuator includes the adjusting actuator for receiving control signal.
Described adjusting actuator can be electric operator, pneumatic actuator or hydraulic actuating mechanism.During use, permanent-magnet speed governor is installed in certain control system, pressure, flow, liquid level or other control signals are received by control system and process, it is then provided to adjusting actuator, controlled the rotation of magnet rotor in first by the actuator of adjusting actuator, change the first iron yoke, the second iron yoke externally shows the size of magnetic.
Due to the fact that and have employed fixing magnetic gap structure, substantially increase the area of contact of speed regulator and reduce 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 it is 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.
