Abstract
The invention relates to an incomplete circular interference-wave magnetic-suspension motor with a complete magnetic ring. The motor is formed by the following steps of: enabling the homopolar magnetic fields of an incomplete circular large magnetic ring (1) and a complete circular large magnetic ring (2) to be opposite, mutually interfere and generate an incomplete circular interference wave (7); enabling a magnetic field of the other polarity of the complete circular large magnetic ring (2) to be opposite to the homopolar magnetic field of an incomplete circular large magnetic ring (3) to generate another incomplete circular interference wave (7); arranging a notch at the upper part; enabling the homopolar end surfaces of a small magnetic ring (4) and a small magnetic ring (5) to be opposite to the homopolar end surface of a small magnetic ring (6), mutually interfering the magnetic fields and jointly mounting on a main shaft (12) to generate small circular interference waves (8) with two polarities; mounting the two small circular interference waves (8) at the inner sides of the two incomplete circular interference waves (7) so that the homopolarities are opposite; and respectively mounting the structures at both ends of a motor rotor (9) and mounting a motor stator (10) in an outer shell (11) to be sleeved at the outer side of the motor rotor.
Description
Affiliated technical field
The present invention relates to a kind of imperfect annular disturbing wave magnetic suspension motor that complete magnet ring is arranged, this magnetic suspension motor is to arrange relatively with three axial charging magnet ring polarity, it is imperfect ring that two magnet rings are wherein arranged, make the mutual interference of three magnet ring homopolar field phases, can produce the highdensity disturbing wave of a kind of imperfect annular this moment; Side is installed three beads identical with the outer shroud magnetizing direction within it again, its polarity is arranged relatively, the mutual interference of two bead homopolar field phases, disturb this moment the magnetic pole end face outside can produce two annular disturbing waves, have these two the high density annular disturbing wave of polarity to be installed in imperfect disturbing wave inboard; Just can drive main shaft this moment and be in the position that upwards suspends automatically; Said structure is installed in the both sides of rotor, on main shaft, adds that rotor just can be suspended in the centre this moment, become the imperfect annular disturbing wave magnetic suspension motor that complete magnet ring is arranged.Belong to the magnetic levitation technology field.
Background technology
The front, we have obtained a kind of high density disturbing wave by test, and this disturbing wave is applicable to symmetrical extruded magnetic suspension bearing.But under symmetrical squeezed state, when being in the base bearing loading capacity of suspended state still off-centre can appear, the needs that can not adapt to horizontal equipment, so we become imperfect magnet ring disturbing wave structure with complete magnet ring disturbing wave architecture advances, by debugging, can make horizontal equipment under the situation of load weight, be in home position when realizing radial suspension.
Summary of the invention
Principle of the present invention is to utilize three big magnet ring polarity of complete annular to arrange relatively, wherein two magnet rings are imperfect ring, make the mutual interference of three magnet ring homopolar field phases, this moment, three magnet ring inboards will produce a N utmost point disturbing wave and a S utmost point disturbing wave, these two disturbing waves that disturbing wave all is imperfect annular; Be installed in three minor diameter magnet rings on the main shaft jointly again, make its homopolar field phase mutual interference, the end face outside, the two poles of the earth of magnet ring can produce the annular disturbing wave of two opposed polarities in the middle of this moment, these two bead high density disturbing waves are installed in the disturbing wave inboard of two imperfect annulars, and this moment, main shaft can be in upwards suspended state automatically; Said structure is installed in the rotor two ends, offsets upwards suspending power of part, make rotor be in the center with rotor weight load.Just become the imperfect annular disturbing wave magnetic suspension motor that complete magnet ring is arranged
Description of drawings
Fig. 1 is the radial section structural map that the imperfect annular disturbing wave magnetic suspension motor of complete magnet ring is arranged of the present invention.
The present invention will be further described below in conjunction with accompanying drawing.
Among Fig. 1, the imperfect big magnet ring of axial charging (1), the complete big magnet ring of axial charging (2), the imperfect big magnet ring of axial charging (3), axial charging bead (4), axial charging bead (5), axial charging bead (6) and two imperfect annular disturbing waves (7), two little complete annular disturbing waves (8), rotor (9), motor stator (10), shell (11) and main shaft compositions such as (12); The big magnet ring of imperfect annular (1) is relative with the big magnet ring of complete annular (2) homopolar field, and the phase mutual interference produces imperfect annular disturbing wave (7); The magnetic field of the another one utmost point of the big magnet ring of complete annular (2) is relative with the homopolar field of the big magnet ring of imperfect annular (3), produces the imperfect annular disturbing wave of another one (7); Breach is on top; Bead (4), bead (5) are relative with bead (6) homopolarity end face, and magnetic field phase mutual interference is installed on the main shaft (12) jointly, produce the little annular disturbing wave (8) of two kinds of polarity; Two kinds little annular disturbing waves (8) are installed in the inboard of two kinds of imperfect annular disturbing waves (7), make its homopolarity correspondence; Said structure is installed in the two ends of rotor (9), motor stator (10) is installed in the shell (11) again, is enclosed within the outside of rotor.
So upwards the weight of suspending power and rotor is cancelled out each other, and just can make rotor be in the center.
