Description
Technical field
The utility model relates to technical field of motors, specifically a kind of tapered air gap axial double loop magnetic field permanent magnet synchronous machine.
Background technology
It is high that permagnetic synchronous motor has efficiency, height of exerting oneself, and speed is adjustable, and dynamic property is good, high reliability.But existing magneto, magnet steel is often arranged in thorax in stator core, because of by spatial limitation, " magnetic energy product " must be selected high, the rare earth magnetic steel that volume is little.This magnet steel is because containing rare earth element Samarium or neodymium (SmCo magnet steel or Nd-Fe-B magnet steel), price is very expensive, and resource-constrained.(certainly, external-rotor motor, also can be arranged in stator core periphery magnet steel, but limits by external diameter equally).Spatial limitation and cost high, significantly limit development and the scope of application of permagnetic synchronous motor.For this reason, the applicant once number of applying for a patent is the utility model patent of 201420685869.X, is solved the shortcoming of above-mentioned conventional permanent magnet motor well, and further increases efficiency, reduce cost by this patent.But along with going deep into patented technology production practices, applicant finds: 1, stator core split is independently present in casing, although have fixed work order below, needs pre-determined bit in advance, wastes time and energy; 2, iron core is folded into by punching, but the operation of the on-mechanical such as " laminating " and " fastening shaping ", more when accounting for, impact batch production.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of tapered air gap axial double loop magnetic field permanent magnet synchronous machine, adopts this motor effectively can improve motor and produces the efficiency of assembling, can also improve the service efficiency of motor simultaneously.
According to the technical solution of the utility model: a kind of tapered air gap axial double loop magnetic field permanent magnet synchronous machine, the stator core comprising casing and be arranged in casing and rotor, it is characterized in that: described stator core has two groups, and two groups of stator core end planes bonded to each other after, be arranged in casing, often organize stator core outer end and all form taper surface, each described taper surface is all equipped with a rotor, and the magnet steel that interlaced arrangement polarity is different on taper surface, described casing inner wall centre position is formed with projection, each described stator core is all arranged with stator winding, between two groups of stator winding by projection separately.
As further improvement of the utility model, described stator core is coiled iron core.
As further improvement of the utility model, the taper surface that stator core outer end is formed is inner conical surface or male cone (strobilus masculinus).
As further improvement of the utility model, described casing two ends connect an end cap respectively, and rotating shaft passes through bearing rotating support on end cap.
As further improvement of the utility model, described stator winding is set around on stator core vertically, and the axis of stator winding parallels with rotating shaft.
Technique effect of the present utility model is: the utility model product carries out technological improvement by the deficiency for existing product, two groups of stator cores are set in casing, often group stator core is all rolled by stamping-out-winding integrated machine and forms, two groups of stator cores are placed back-to-back simultaneously, two groups of stator cores are formed independently " sub-motor " with the cone rotor at two ends respectively, two overlap " sub-motor " and the used time, can also according to the condition of power supply, and in parallel or series connection uses.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
In Fig. 1 ~ 8, comprise stator core 1, taper surface 1-1, stator winding 2, magnet steel 3, rotor 4, bearing 5, rotating shaft 6, end cap 7, casing 8, protruding 8-1 etc.
As shown in Fig. 1 ~ 8, the utility model is a kind of tapered air gap axial double loop magnetic field permanent magnet synchronous machine, the stator core 1 comprising casing 8 and be arranged in casing 8 and rotor 4, described stator core 1 has two groups, and two groups of stator core 1 end planes bonded to each other after, be arranged in casing 8, often organize stator core 1 outer end and all form taper surface 1-1, each described taper surface 1-1 is all equipped with a rotor 4, and the magnet steel 3 that interlaced arrangement polarity is different on taper surface 1-1, to form tapered air gap in casing, described casing 8 inwall centre position is formed with protruding 8-1, each described stator core 1 is all arranged with stator winding 2, between two groups of stator winding 2 by protruding 8-1 separately, formed two " sub-motor ", in use, can only with a set of, also can two overlap and use, the instructions for use of different client can be met preferably, effectively can improve service efficiency.
As shown in Figure 4, stator core 1 is coiled iron core, and this stator core 1 in the fabrication process, adopts stamping-out-winding integrated machine to roll and forms.As shown in Figure 7, overlap independently stator winding 2 by being placed back-to-back by two stator cores 1 and arranging two, match with the rotor 4 of cone-shaped respectively, form two separate " sub-motors ", coaxially operate.
