The utility model discloses reliable and simple has, and it is with low costs, improve the positive effect of production efficiency and safety guarantee.
Description
Technical field
The utility model relates to permanent magnet motor technical field, belongs to a kind of novel rotor of permanent magnet motor especially.
Technical background
Large-scale permanent magnet motor is an inexorable trend of development of modern industry, but the manufacturing process of permanent magnet motor maximization and assembly problem hinder the development of this trend.The rotor size of large-scale magneto is too large, and entirety cannot be adopted to magnetize technique; Assemble the rotor of magnet steel, due to the existence of high-intensity magnetic field, easily cause a series of problem, such as, the phenomenon of colliding with in transport process, the cleaning problems in preservation process, when most importantly rotor is installed, large-scale special equipment and matching tooling instrument need be adopted to ensure all even concentricity of air gap, waste time and energy, there is serious potential safety hazard, and maintenance overhaul is difficult.
Utility model content
The purpose of this utility model is to provide a kind of permanent magnet motor novel rotor, to reach interim demagnetization before transportation and installation, to be convenient to install and improve the object of safety guarantee.
Permanent magnet motor novel rotor disclosed in the utility model, has rotor core, is overrided to form by rotor iron core lamination, middle part has axis hole, it is characterized in that, described rotor core also has fixed magnetic pole groove, rotary pole groove, wherein arranges fixed magnetic pole, rotary pole assembly respectively.Rotary pole groove side has introversive half hole slot; Described rotary pole assembly has the magnetic pole body that pole lamination is formed, magnetic pole body edges be provided with in rotary pole groove to extroversion half hole slot that half hole slot is corresponding, magnetic pole body is provided with magnetic pole groove, places magnetic pole in magnetic pole groove.
Above-mentioned magnetic pole body can also be provided with fabrication hole, be convenient to the rotation that engagement tool realizes rotary pole assembly.
Permanent magnet motor novel rotor disclosed in the utility model, entering non operating state, namely carry out processing, transport or keep in repair, when assembling, embed and the opposite polarity magnetic pole of normal operating conditions in the magnetic pole groove of rotary pole assembly, itself and fixed magnetic pole is made to form closed magnetic circuit in rotor core, thus make whole rotor externally not aobvious magnetic, then get the location hole that an alignment pin puts into above-mentioned introversion half hole slot and export-oriented half hole slot correspondence formation, make rotary pole assembly relative with rotor core fixing; When entering normal operating conditions, take out alignment pin, rotary pole assembly can be rotated in the rotary pole groove of rotor core, rotate rotary pole assembly, the polarity of magnetic pole is made to meet the magnetic structure requirement of operating state, then alignment pin is reentered into location hole, makes rotary pole assembly relative with rotor core fixing; When again entering non operating state, again take out alignment pin, rotary pole assembly can be rotated in the rotary pole groove of rotor core, rotate rotary pole assembly, make the polarity when polarity of magnetic pole and operating state contrary, thus make whole rotor externally not aobvious magnetic, then alignment pin is reentered into location hole, makes rotary pole assembly relative with rotor core fixing.
Permanent magnet motor novel rotor disclosed in the utility model, rotor is processed, transports, when assembling, portion magnetic pole in built-in tangential magnetic circuit is made rotary structure, make itself and fixed magnetic pole directly form field circuit in rotor core inside, make whole rotor externally not aobvious magnetic, avoid the interference due to high-intensity magnetic field in operation process, the work inconvenience that may bring and potential safety hazard, have simple, cost is low, enhances productivity and the good effect of safety guarantee.
Accompanying drawing explanation
Fig. 1 is the structural representation under utility model works state;
Fig. 2 is the structural representation under the utility model non operating state;
Fig. 3 is rotor core structure schematic diagram;
Fig. 4 is the magnetic pole body construction schematic diagram of rotary pole assembly of the present utility model.
Embodiment
Permanent magnet motor novel rotor disclosed in the utility model, has rotor core 6, as shown in Figure 3, rotor core is overrided to form by rotor iron core lamination, middle part has axis hole 5, and also have fixed magnetic pole groove 7, rotary pole groove 9, rotary pole groove side has 2 introversion half hole slots.
Described rotary pole assembly has shown in the magnetic pole body 10, Fig. 4 of pole lamination formation, and magnetic pole body edges has 2 semicircular export-oriented half hole slots, magnetic pole body has the magnetic pole groove 8 of 4 fabrication holes 4 and middle position.
Form dowel hole 2 to half hole slot in above-mentioned export-oriented half hole slot and rotary pole groove, as required, coordinate alignment pin realize the fixing of rotary pole assembly or remove fixing.
As shown in Figure 1 and Figure 2, fixed magnetic pole groove 7, the rotary pole groove 9 of rotor core wherein arrange fixed magnetic pole 1 and rotary pole assembly respectively, place magnetic pole 3 in the magnetic pole groove of rotary pole assembly.
Rotary pole assembly of the present utility model can rotate in the rotary pole groove of rotor core, makes the polarity of its magnetic pole 3 in running order or non operating state respectively.When rotating rotary pole assembly, can be realized by fabrication hole 4 by instrument; After rotation completes, can realize fixing with because of coordinating of hole by alignment pin.Above means all belong to those skilled in the art and easily expect and can realize, therefore do not do too much explanation.
Claims (2)
