[0001] 本发明涉及电机,尤其涉及同步磁阻电机。 [0001] The present invention relates to a motor, and particularly to a synchronous reluctance motor. 背景技术 Background technique

[0002] 交流感应异步电机有很长的历史背景,是目前应用最广的电机。 [0002] AC asynchronous induction motor has a long historical background, is currently the most widely used motors. 随着全球能源的日益紧张,人们通过各种方法试图提高感应电机的效率来满足对能源的苛刻要求,传统的方法有:增加定子绕组的线径,减小定子绕组电阻来减小定子铜损;使用更好材料的定子、 转子冲片来减小电机的铁损;优化电机转子设计,铸铜来替代铸铝,减少转子损耗;优化电机风道设计,减小风摩擦损耗。 With the growing global energy tensions, attempts by various methods to improve efficiency of the induction motor to meet the demanding requirements for energy, the traditional methods are: increasing the diameter of the stator winding, the stator winding is reduced to decrease the resistance of the stator copper losses ; use of better materials in the stator, and rotor plate to reduce the iron loss of the motor; optimum motor rotor design, cast aluminum instead of copper, to reduce the rotor losses; optimal motor duct design, reduce wind friction loss.

[0005] 由于永磁同步电机具有上述因素限制,所以在高效领域中很难走得更远,只限于在特殊场合使用,比如:高功率密度、高转矩密度需求。 [0005] Since the permanent magnet synchronous motor having the above constraints, it is difficult to go further in the field of high efficiency, only be used for special occasions, such as: high power density, high torque density requirements. 发明内容 SUMMARY

[0017] 如图1到图2所示,一种同步磁阻电机,包括转子3和定子,所述转子3设置在所述定子上,其特征在于:所述转子3包括转子铁芯,所述转子铁芯包括m组绕所述转子的转轴周向间隔均匀分布的隔磁栅组件,每一组所述隔磁栅组件包括n层沿所述转子的径向间隔分布的隔磁栅31,其中,m为不包括0的正偶数,n为正整数,所述隔磁栅31为圆弧形。 [0017] As shown in Figure 1 to a synchronous reluctance motor 2 comprising a rotor and a stator 3, a rotor 3 disposed on the stator, characterized in that: the rotor 3 comprises a rotor core, the said rotor core includes m magnetic spacer grid assembly being wound around the rotor shaft spaced evenly distributed, each set of said radial magnetic spacer grid assembly comprising a layer of n spaced along the rotor flux barrier gate 31 wherein, m is a positive even number not including 0, n is a positive integer, the magnetic isolation gate 31 is arcuate. [〇〇18]如图1到图2所示,所述隔磁栅31与所述转子的圆形端面相交。 [〇〇18] shown in FIG. 1 to FIG. 2, the magnetic isolation gate 31 intersects the circular end surface of the rotor. [〇〇19] 如图1到图2所示,所述转子包括4组隔磁栅组件。 [〇〇19] shown in FIG. 1 to FIG. 2, the rotor comprises four groups of magnetic spacer grid assembly.

[0020] 如图1到图2所示,每一组所述隔磁栅组件包括4层隔磁栅31。 [0020] As shown in FIG 1 to FIG. 2, each set of said grid assembly comprises a magnetic isolation barrier magnetic layer 4 of the gate 31.

[0021] 如图1到图2所示,所述定子包括定子铁芯1和绕在所述定子铁芯1上的定子绕组2。 [0021] As shown in Figure 1 to the stator 2 includes a stator core 1 and the stator core wound on a stator winding 2.

[0022] 如图1到图2所示,所述转子的高磁导率轴标定为d轴33,所述转子的高磁阻轴标定为q轴32,相邻两组所述磁栅组件之间的中线为d轴33,每一组所述隔磁栅组件包括n层沿所述q轴32间隔分布的隔磁栅。 [0022] As shown in FIG. 1 to the high magnetic permeability of the rotor shaft 2 of FIG. 33 labeled as the d-axis, high magnetic reluctance of the rotor shaft calibration q-axis 32, the two adjacent magnetic grid assembly between the d-axis centerline 33, each set of said grid assembly comprises a magnetic isolation layer in the n q-axis flux barrier 32 spaced grid. [〇〇23]如图1到图2所示,所述隔磁栅31上设有加强筋。 [〇〇23] shown in FIG. 1 to FIG. 2, the barrier 31 is provided with reinforcing ribs on the magnetic grid.

[0024] 同步磁阻电机与交流感应电机具有相同的定子结构,定子由定子铁芯1和定子绕组2构成,定子绕组2在施加正弦交流电的情况下,在气隙中产生交变的旋转磁场。 [0024] The synchronous reluctance motor and the AC induction motor has the same stator structure, a stator 1 includes a stator core and a stator winding 2, in the case of a sinusoidal alternating current in the stator winding 2, an alternating rotating magnetic field in the air gap .

[0025] 交流感应电机转子多为常用的鼠笼结构,由转子铁芯和铸铝闭合回路构成,此种结构会产生24%的损耗。 [0025] AC induction motors are commonly used on rotor squirrel cage configuration, a closed circuit constituting the rotor core and aluminum, this structure will have a 24% loss. 磁阻电机转子不同于感应电机,采用创新型磁阻结构(如图2所示), 转子铁芯被冲成不同形状的隔磁栅,没有铸铝材料构成的闭合回路,因此同步磁阻电机可以做成转子零损耗,因此很容易设计IE4高效电机。 Unlike reluctance motor rotor induction motor, reluctance innovative structure (FIG. 2), the rotor core is punched into various shapes flux barrier gate, no closed circuit formed of aluminum material, and therefore the synchronous reluctance motor The rotor loss can be made zero, it is easy to design efficient IE4 motor. [〇〇26]本发明提供的一种同步磁阻电机的工作原理为:由于磁阻结构转子具有方向各异性特点,换句话说就是不同方向磁导率不同,图2为4 极结构的转子结构,具有4高、4低的磁导率轴,高磁导率意味着高导磁能力,也可以理解为高电感,相反低磁导率具有相反的特性。 [〇〇26] working principle of a synchronous reluctance motor according to the present invention is provided as follows: due to the direction of the magnetoresistive structure having anisotropic characteristics of the rotor, in other words different permeability in different directions, FIG. 2 is a 4-pole rotor structure structure, having a high 4, 4-axis low permeability, high magnetic permeability means a high capacity, a high inductance can be understood as the contrary of low permeability having opposite characteristics. 磁阻是磁导率的倒数,专业术语中叫磁电阻,高磁阻可以理解为低电感,为了实现矢量控制因此将高磁导率轴标定为d轴33,相反高磁阻轴标定为q轴32。 Is the inverse of reluctance magnetic permeability, in the jargon called magneto-resistive, high magnetic reluctance will be appreciated that a low inductance, thus the control vector in order to achieve a high permeability calibration d-axis shaft 33, opposite to the high reluctance axis nominally q the shaft 32. 定子绕组2施加正弦波电压时,电机气隙中就产生旋转磁场,转子会强制向高导磁d轴33对齐,以形成最小磁回路,于是在定子、转子气隙中就产生了转矩,电机就转起来了。 The stator winding 2 is applied sinusoidal voltage, the motor generates a rotating magnetic field in the air gap, the rotor is forced to the d-axis 33 aligned with high permeability, a magnetic circuit to form a minimal, so in the stator, a rotor air gap torque is generated, the motor will turn up.

[0027] 同步磁阻电机与交流感应电机具有相同的定子结构,因此在设计中不对定子做太多的描述,以下将重点介绍隔磁栅31的设计。 [0027] AC synchronous reluctance motor induction motor stator has the same structure, and therefore in the design of the stator do not much description below will focus on the design of the gate 31 of the magnetic separator.

[0028] 隔磁栅31角度确定,根据电机的技术要求首先确定电机的极数,也就是d、q轴的角度,本例中采用4极设计,因此d、q轴的机械角度是45度。 [0028] The spacer 31 angle magnetic grid determined, first determine the number of poles of the motor according to the technical requirements of the motor, i.e. the angle d, q-axis, the present embodiment uses four-pole design, therefore d, the mechanical angle of the q-axis is 45 degrees . [〇〇29]隔磁栅31层数确定,同步磁阻电机的设计使用FEM(有限元仿真软件),通过该软件可以对每个隔磁栅31进行转矩输出仿真,根据电机设计转矩指标通过FEM软件可以确定隔磁栅31的布局和排列方式(即层数),本例同步磁阻电机为15kw、1500转/分钟,额定转矩是95.5牛.米,采用的是4层隔磁栅31设计。 [〇〇29] magnetic grid spacer 31 determines the number of layers, a synchronous reluctance machine design using FEM (finite element simulation software), the output torque can be simulated for each compartment 31 through the magnetic grid software according to design motor torque indicators may be determined by the FEM software magnetic spacer grid layout and arrangement 31 (i.e. number of layers), the present embodiment is a synchronous reluctance machine 15kw, 1500 rev / min, rated torque is 95.5 Nm, barrier layer 4 is used 31 magnetic grid design.

[0030]隔磁栅31形状确定,使用FEM软件每次仿真时保持电流的幅值恒定,角度以产生最大转矩,逐渐增加隔磁栅31的宽度,转矩从最初值开始增加,原因是当q轴32磁阻迅速增加时,d轴33磁阻没有变化,隔磁栅31宽度在增加过程中电机的转矩脉动也在变化,当隔磁栅31宽度达到某个值后,电机的转矩脉动趋于恒定、最小,此时的隔磁栅31宽度即为最佳设计。 [0030] The flux barrier gate 31 determines the shape to use FEM software to maintain a constant amplitude of the current during each simulation, to generate maximum torque angle, gradually increasing the width of the magnetic grid spacer 31, the torque begins to increase from an initial value, due when a rapid increase in the q-axis magnetoresistive 32, d-axis magnetoresistive no change 33, a gate 31 separated from the magnetic width increasing process is changing the motor torque ripple, the magnetic barrier when the gate width 31 reaches a certain value, the motor torque ripple tends to be constant, minimum width 31 at this time is the best magnetic grid spacer design. 为了得到更小的齿槽转矩和转矩脉动还要优化隔磁栅31的弧度设计,同时考虑电机转子的强度要求,还要优化隔磁栅31加强筋设计。 In order to obtain a smaller cogging torque and torque ripple even curvature of the design optimization of the flux barrier gate 31, while considering the strength required of the rotor, but also to optimize the gate 31 separated from the magnetic bead design. [0031 ]本发明提供的一种同步磁阻电机的优势如下:1、IE4超级高的效率,经过优化的同步磁阻电机,标准的机座号可实现IE4的能效标准。 [0031] The advantage of a synchronous reluctance motor according to the present invention are as follows: 1, IE4 super high efficiency, optimized synchronous reluctance machine, the standard frame sizes may be implemented in IE4 energy efficiency standards. [0032 ] 2、无磁设计,同步磁阻电机技术结合了永磁电机的性能和感应电机的可制造性,转子既没有磁钢也没有线圈,与普通感应电机相比维护相当简单,同时成本很低。 [0032] 2, non-magnetic design, a synchronous reluctance motor technologies manufacturability of permanent magnet motor and an induction motor performance, neither rotor magnets nor coils, compared with the conventional induction motor to maintain relatively simple, while the cost of very low. [〇〇33] 3、超级可靠最大减少热停,70%的感应电机热停是由于轴承的失效引起,轴承失效的主要原因为温度过高,IE4同步磁阻电机具转子零发热特性,可以大幅提高电机的寿命。 [〇〇33] 3, reducing the maximum thermal super reliably stopped, 70% of the induction motor is stopped due to the heat caused by failure of the bearing, bearing failure is mainly due to high temperature, IE4 zero synchronous reluctance machine having a rotor heat generation characteristics, can be a substantial increase in motor life. [〇〇34] 4、高能效的获取不需改变原电机的机械设计,不像很多其他的高效电机,为了得至IJIE4能效电机所有设计都需要修改,包括:定子、转子、绕组、风道设计等。 [〇〇34] 4, to obtain high efficiency without changing the mechanical design of the original machine, unlike many other high-efficiency motors, in order to obtain all IJIE4 energy efficient motor design need to be modified, comprising: a stator, a rotor winding, duct design. 而IE4同步磁阻电机设计,可以利用原有感应电机所有机械数据、材料,只需重新设计转子就可以实现IE4 能效,具有开发成本低、时间短,系列形成快等优点。 IE4 the synchronous reluctance machine design, can use the existing induction motor all the mechanical data, materials, simply re-design of the rotor can be realized IE4 energy efficiency, the development of low cost, short time, the advantages of quick series form. 易于制造、生产,同步磁阻电机定子与传统的感应电机一样,设计、制造技术已非常成熟,而转子完全由硅钢片叠压而成,没有感应电机绕组(铸铝),不但加工、制造简单,成本也有所下降。 Ease of manufacture, production, and a synchronous reluctance motor stator as the conventional induction motor, the design, manufacturing technology has been very mature, and fully laminated rotor made of silicon, there is no induction motor winding (aluminum), only processing, manufacturing is simple , costs also declined.
