Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-7, a kind of praseodymium neodymium permanent magnet submersible pump motor Special rotor, including in set iron plate 4 and rotor housing
9, in set iron plate 4 be specially electrical pure iron made of iron plate, trade mark DT4E-DT4C, in set 4 parallel inserted of iron plate outside rotor
In set 9, in set 4 one end of iron plate lower semiaxis 3 be installed, the other end is equipped with semiaxis 2, at the axis of upper semiaxis 2 and lower semiaxis 3
In on same straight line, and to set iron plate 4 in symmetrical for upper semiaxis 2 and lower semiaxis 3, in set about 4 two sides of iron plate and be adhesive with partly
Month type magnetic material 5, half-moon-shaped magnetic material 5 be praseodymium neodymium iron boron mixed sintering at half-moon-shaped block, trade mark N-52, half-moon-shaped magnetic material
5 lateral walls are close to 9 inner wall of rotor housing, half-moon-shaped magnetic material 5 be bonded in set 4 two sides of iron plate, used jointing material is
Quick epoxy resin, half-moon-shaped magnetic material 5 and in set and be coated with epoxy structural rubber on iron plate 4, in set iron plate 4 and half-moon-shaped magnetic material
It is TY5324, TY5326 and JL6236 adapted promotor that used adhesive, which is epoxy structural rubber, in 5 indentation rotor housings 9
JL-7649 sets on 9 inner wall of 4 side of iron plate and rotor housing correspondence in and offers keyway 10, in set iron plate 4 and rotor housing 9
Spline 6 is embedded in by keyway 10 to be locked, and the silicon steel sheet 1 of circular ring shape, silicon steel sheet are installed at 9 both ends port of rotor housing
Uniform intervals offer the flat aluminum cast groove 8 of multiple pears types with 1, and 1 body two sides of silicon steel sheet be symmetrically arranged with long arris type every
Magnetic bridge 7, flat 8 quantity of aluminum cast groove of pears type is specially 16, and 1 inside of silicon steel sheet is corresponding with rotor housing 9 to offer keyway 10.
Compared with traditional induction electromotor rotor, this casting aluminum rotor, copper bar squirrel cage are only starting rotor of the present invention
When work, induce electric current and generate rotation, praseodymium neodymium permanent magnetic field draws spinner velocity by force to operating synchronously after starting, this
When revolution and supply frequency there is no rotational speed difference with frequency, between stator and rotor, rotor cage does not just have induced AC current yet, so
Motor is idle, and power consumption is greatly lowered.
The present invention also provides a kind of preparation methods of praseodymium neodymium permanent magnet submersible pump motor Special rotor, and specific steps are such as
Under:
S1, by 45# steel round steel blanking, the upper and lower semiaxis of predetermined size is made through lathe, by upper and lower semiaxis one end position
Punching, other end fluting, the width of notch set 4 strict conformance of iron plate in；
S2, set iron plate by and be inserted into upper and lower half shaft relief, adjustment center distance is simultaneously welded, become one it is whole
Body is pedestal；
S3, by lathe turning on pedestal, be ground to specification error, and iron plate 4 is set in grinding because of the burr that generates when turning；
S4, by two blocks of half-moon-shaped magnetic materials 5 with epoxy resin be pasted onto set 4 two sides of iron plate, after cured constitute rotor it is whole
Axis；
S5, rotor bearing outer circle is applied into structure glue, is pressed into rotor housing 9 and keyway 10 together with spline 6, to structure
P-m rotor is constituted after adhesive curing；
S6, by lathe finish turning in the rotor blank, until specification error；
S7, grinding machine on the good rotor of vehicle is refined；
S8, the rotor of milled is corrected into dynamic balancing；
S9, magnetizing are tested into control laboratory, and qualification installation, unqualified to scrap, waste disposal is made in dismantling.
Illustrate: 1, magnetizing is radial magnetizing, and magnetic pole S, N are opposite.2, cast aluminium copper rotor is different from convention rotor, turns
If sub- cast aluminium area is excessive, rotor punching silicon steel sheet area will reduce, and certainly will influence magnetic permeability；It is opened if cast aluminium area is too small
Dynamic performance is bad, and for above-mentioned condition, rotor punching of the present invention uses oval flat groove profile, long arris type magnetic bridge road piece, and
It is a set of to develop transfer rotor punching mould, under the premise of not increasing magnetic resistance, increases cast aluminium area.
Asynchronous starting, permanent-magnetic synchronous motor rotor working principle are as follows: starting is initial, the rotor and ordinary motor
Equally, it when stator winding is presented with 50Hz three-phase alternating current, generates and the consistent rotation of frequency touches a rotor and touches field in rotation
It under effect, generates induced electromotive force and forms induced magnetic field, and touched what stator rotating excitation field and rotor induction kinetic potential were formed
Under field interactions, rotor starts to rotate, and when reaching asynchronous speed, is pulled in by force by praseodymium neodymium magnetic material ultrastrong magnetic field, this
It is synchronous with rotary speed of rotator that field is touched in Shi Dingzi rotation, due to there is no a slip, cast aluminium copper comb cage no longer incude AC electromotive force and
It rotates and does work by praseodymium neodymium permanent-magnet magnetic magnetic field drive rotor.
When network voltage reduces, motor speed will not decline the present invention, and lift, the flow of water pump will not be with power grids
Voltage reduces and declines.
Present invention work is operating synchronously state, does not have rotational speed difference between the rotating excitation field generated due to stator and rotor,
Casting aluminum rotor copper comb cage does not just have induced current yet, and rotor does not have reactive loss, so Overall Power Consumption will be greatly reduced, such as
Common 200 type 800-22-7.5kW Rated motor operating current 18A, and 200 type 80-22-7.5kW motors of permanent-magnet synchronous rotor
Rated operational current is only 15.45A.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
