Abstract
The utility model relates to a permanent magnet synchronized electric powered rotator and a rotator punching sheet in the FTY 2 system, belonging to the small sized motor manufacturing art. The utility model aims to provide a structure which makes the rotator punching sheet integrated to make the noise low, the life long and the operation stable. The utility model is realized by that the permanent magnet synchronized motor rotator comprises a rotor cage, a magnet steel, a steel core and a shaft, the steel core is overlapped and pressed on the shaft, and the steel core is formed by the overlapping of a plurality of rotator punching sheets, characterized in that the rotator punching sheet is an integral structure, wherein the round circle face is punched with an opening guide plate dent, the inside of the guide plate is symmetrically equipped with a plurality couples of 'V' shaped magnet steel equipping dent, and the magnet steel is equipped inside the equipping dent. The utility model has the advantages that the motor can act as a drive source of a frequency variation stepless speed regulation or a constant speed device, the rotary speed preciseness is high, and the energy is saved high effectively, which can replace a compatible the same power FTY system motor.
Description
Technical field:
The utility model relates to a kind of synchronous permanent-magnet motor rotor and rotor punching of FTY2 series, belongs to miniature motor and makes the field.
Background technology:
The present minitype permanent magnetism synchronous motor of selling on the domestic market, the one, aspect the magnetic circuit and structural design of its rotor, rotor punching is not an overall structure, the magnetic shielding structure design is undesirable, makes that this structure is not only complicated, leakage field is big, and anufacturability is poor; The 2nd, adopt nonmagnetic substance to make magnetic shield and cooperates with axle afterwards, even use costs an arm and a leg but the relatively poor stainless steel material of processability and mechanical performance is made motor shaft every magnetic every magnetic, this structure not only cost height, its effect is not good yet; The 3rd, magnetic flux distribution is inhomogeneous between each magnetic pole, causes noise of motor and vibration bigger, and not only run stability is poor, and useful life is short.
Summary of the invention:
The purpose of this utility model is the complex structure that overcomes above-mentioned minitype permanent magnetism synchronous motor, leakage field is big, manufacturability is poor, cost height, short shortcoming of life-span, it is the structure of holistic permanent magnet synchronous motor that a kind of its rotor punching is provided, and makes that its noise is little, efficient is high, the life-span is long, running is stable.
The utility model is achieved in that permanent-magnet synchronous motor rotor comprises mouse cage 1, magnet steel 2, iron core 3 and axle 4; Iron core 3 is laminated on the axle 4, and described iron core 3 is formed by stacking by multi-disc rotor punching 6; It is characterized in that: described rotor punching 6 is an overall structure, and its periphery upper punch has opening sliver groove 61, and sliver 8 is embedded in the opening sliver groove 61, and the center of rotor punching 6 has axis hole 62, and with axle 4 tight fits; The inboard symmetry of opening sliver groove 61 has many to " V " type magnet steel mounting groove 9, and the opening direction of " V " type inwardly, and magnet steel 2 is installed in the magnet steel mounting groove 9, and the part between the corresponding end of described adjacent two magnet steel mounting grooves 9 is a magnetic bridge 5.
Described sliver 8 adopts copper or aluminum to do.
Described opening sliver groove 61 is the pyriform structure.
The material of described magnet steel 2 adopts rare earth permanent-magnetic material.
The utility model has the advantages that, because of rotor punching is an integral body, leakage magnetic circuit adopts every magnetic magnetic bridge structure Design, make not only that the axle 4 and the iron core 3 of rotor are easy to firm binding, noise is little, run stability good, long service life, and make motor can make the drive source of variable-frequency stepless speed-regulating or constant speed equipment; Owing to its rotating speed is directly proportional with supply frequency and turns round with leg speed, so the rotary speed precision height; Because magnet steel is excitatory, so no slip and excitatory loss are energy-efficient; Because the FTY2 serial motors is to adopt rare earth permanent-magnetic material to develop on FTY series basis, performance is more excellent, can substitute compatible with power FTY serial motors fully.
