Abstract
The utility model relates to a kind of novel rotor dish of disc brushless coreless permanent magnet motor.It draws together the shaft hole that rotor disk body and the center offer, it is characterized in that: described rotor disk body is circular plate type, the upper side wall of rotor disk body is provided with the magnet steel groove for mounting magnetic steel, and offering overall at the outer edge place of rotor disk body lower wall is circular oblique angle.By arranging magnet steel groove at the sidewall of rotor disk body, during use alinco assembled in magnet steel groove, circumferential sidewall and the magnet steel recess sidewall of magnet steel fit tightly, therefore magnet steel also difficult drop-off when high speed rotating; By offering oblique angle at the outer edge place of rotor disk body lower wall, and oblique angle entirety is circular, and corresponding with the periphery of magnet steel, curvature forms a magnetic loop, greatly reduces magnetic loss, effectively increases magnetic utilance.
Description
Technical field
The utility model relates to a kind of rotor of disc brushless coreless permanent magnet motor, especially relates to a kind of Novel motor rotor dish of this motor.
Background technology
The DC permanent magnet high-speed electric expreess locomotive of current use, owing to adopting structure glue or other adhesives, be fixed on rotor by magnet steel, if magnet steel, rotor surface process are clean, magnet steel is very easy to come off, even operate in strict accordance with standard-required, rotor, under High Rotation Speed, only leans on the suction of viscous force and magnet steel, is also difficult to ensure that magnet steel can not come off, this magnet steel fixing means is unreasonable, cannot ensure the long-time running of DC permanent magnet high-speed electric expreess locomotive.Meanwhile, because magnet steel projection is at rotor surface, thus the remanent magnetism of magnet steel is higher, and magnetic field utilance is low, and the width blackberry lily in magnetic field disturbs external circuitry and miscellaneous equipment, and Electro Magnetic Compatibility is poor.
Summary of the invention
The utility model provides and a kind ofly on the upper side wall of rotor disk body, is provided with magnet steel groove, offers the Novel motor rotor dish at oblique angle at the outer edge place of lower wall; The magnet steel existed in solution prior art easily comes off, remanent magnetism is higher, and magnetic field utilance is low, and the width blackberry lily in magnetic field disturbs external circuitry and miscellaneous equipment, the technical problem of the poor grade of Electro Magnetic Compatibility.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of Novel motor rotor dish, comprise the shaft hole that rotor disk body and the center offer, it is characterized in that: described rotor disk body is circular plate type, the upper side wall of rotor disk body is provided with the magnet steel groove for mounting magnetic steel, and offering overall at the outer edge place of rotor disk body lower wall is circular oblique angle.By arranging magnet steel groove at the sidewall of rotor disk body, during use alinco assembled in magnet steel groove, circumferential sidewall and the magnet steel recess sidewall of magnet steel fit tightly, therefore magnet steel also difficult drop-off when high speed rotating; By offering oblique angle at the outer edge place of rotor disk body lower wall, and oblique angle entirety is circular, and corresponding with the periphery of magnet steel, curvature forms a magnetic loop, greatly reduces magnetic loss, effectively increases magnetic utilance.
As preferably, the circumferential sidewall of described rotor disk body is provided with dismounting angle.Dismounting angle be provided with the assembling and dismounting that are beneficial to rotor disk, simultaneously be also conducive to decreasing magnetic loss.
As preferably, described dismounting angle is the pointed shape of indent, and dismounting angle is located on inclined-plane corresponding to oblique angle.Be conducive to decreasing magnetic loss, increase magnetic utilance.
As preferably, described dismounting angle entirety is circular.Be conducive to assembling and the dismounting of rotor disk.
As preferably, the upper side wall of described rotor disk body is also provided with and becomes the coaxial inner groovy arranged with magnet steel groove, described inner groovy is located between magnet steel groove and shaft hole, and the height of magnet steel groove is less than the height of inner groovy.The setting of inner groovy allows the magnetic field of magnet steel better form a loop, reduces the dispersion in magnetic field, improves the utilance in magnetic field.
As preferably, described magnet steel groove is annular.Magnet steel groove is set to annular and coordinates with the magnet steel of annular, sound construction, and magnetic utilance is high.
Therefore, the utility model has following characteristics compared to existing technology: 1. by arranging magnet steel groove at the sidewall of rotor disk body, during use alinco assembled in magnet steel groove, circumferential sidewall and the magnet steel recess sidewall of magnet steel fit tightly, therefore magnet steel also difficult drop-off when high speed rotating; 2. by offering oblique angle at the outer edge place of rotor disk body lower wall, and oblique angle entirety is circular, and corresponding with the periphery of magnet steel, curvature forms a magnetic loop, greatly reduces magnetic loss, effectively increases magnetic utilance.
