Description
Technical field
The utility model relates to compressor and technical field of motors, particularly a kind of magnet ring fixing structure being applied to magnet ring motor.
Background technology
Tradition adopts the frequency-changeable compressor of magnet ring motor, often only by rotor core interference fit or glue, magnet ring is fixed on rotor core surface, to prevent magnet ring play.And only use interference fit, reliability is poor, and can increase production process (as gluing, drying glue etc.) with glue is fixing, be inconvenient to produce and fix, gluing is uneven simultaneously, motor gas-gap can be made uneven, be unfavorable for the production of small air gap motor, moreover magnet ring fixed form in the past, in order to axial limiting, often some leaks at magnet ring outside iron core, causes magnetic field leakage field, make electric efficiency, and then affect compressor COP.So how to solve the fixation problem of frequency-changeable compressor magnet ring motor, it is the problem that machine designer pays close attention to always.
Summary of the invention
For solving the problems of the prior art, the utility model provides a kind of novel structure, the magnet ring fixing structure that easy to use, stable performance is applied to magnet ring motor.
For solving the problems of the technologies described above the technical solution of the utility model be: a kind of magnet ring fixing structure being applied to magnet ring motor, comprise rotor core and magnet ring, it is characterized in that: the cylindrical of described rotor core one end face is provided with boss one, inside is provided with through hole, described magnet ring one end face has three grooves matched with the outer circular bosses one of rotor core, inside is provided with the boss two matched with end plate, described end plate is provided with the hole matched with rotor core interior bone, in described hole and through hole, is provided with rivet.
The number of described boss one is 3, is spaced apart 120 ° between each boss one.
The number of described groove is 3, is spaced apart 120 ° between each groove.
The number of described through hole is 3, is spaced apart 120 ° between each through hole.
The number of described hole is 3, is spaced apart 120 ° between each hole.
The utility model is by adopting overall magnet ring; conventional permanent magnet can be saved and fix required glue etc.; permanent magnet is directly fixed on rotor core on the surface by mounting bracket; easy for installation and reliable; motor gas-gap is more even simultaneously, and motor rotation is more steady, has good protective effect to magnet ring opposing centrifugal force; simultaneously lower, the stable performance of magnet ring fixing structure manufacturing cost, therefore has wide market prospects.

Embodiment
As shown in figs. 1-7, a kind of magnet ring fixing structure being applied to magnet ring motor, comprise rotor core and magnet ring, the cylindrical of described rotor core 1 one end face is provided with boss 1, inside is provided with through hole 6, and described magnet ring 2 one end face has three grooves 7 matched with the outer circular bosses 1 of rotor core 1, and inside is provided with the boss 28 matched with end plate 3, described end plate 3 is provided with the hole 9 matched with rotor core 1 interior bone 6, in described hole 9 and through hole 6, is provided with rivet 4.
The number of described boss 1 is 3, is spaced apart 120 ° between each boss 1.
The number of described groove 7 is 3, is spaced apart 120 ° between each groove 7.
The number of described through hole 6 is 3, is spaced apart 120 ° between each through hole 6.
The number of described hole 9 is 3, is spaced apart 120 ° between each hole 9.
The assemble method of the utility model magnet ring fixing structure is as follows:
What the present embodiment magnet ring adopted is parallel magnetization, radial magnetizing, Halbach array (Halbach),
3 grooves 7 are opened, 120 °, each groove interval in a side end face of magnet ring 2; 3 boss 1 are designed, each 120 °, boss 1 interval at the outer fenestra of a side end face of rotor core 1.The boss 1 of rotor core 1 and the groove 7 of magnet ring 2 match, and rotor core 1 completes and sinks into magnet ring 2, both can prevent magnet ring 2 from tangentially rotating, and greatly can reduce again the leakage field that rotor core 1 produces, the efficiency of lifting motor, and then promote the COP of compressor.
By magnet ring 2, rotor core 1, end plate 3, rivet 4 according to setting shown in Fig. 1 on the riveting tool that is placed on and designs in advance, applying suitable pressure, magnet ring 2 firmly can be fixed on rotor core 1 surface.
Above-mentioned magnet ring structure has abandoned the form of fixed permanent magnet such as surface-mounted rotor employing in the past glue and interference fit etc., make the reliability of rotor higher and easier for installation, manufacturability and to manufacture efficiency higher, can solve the leakage field of rotor core generation when tradition fixes magnet ring simultaneously.
The above; be only the utility model preferably embodiment; but the utility model protection range is not limited thereto, such as, is equal to according to the technical solution of the utility model and inventive concept thereof and replaces or change, all should be encompassed within protection range of the present utility model.
