Description

一种导磁环定子圆筒形直线开关磁阻电机A Cylindrical Linear Switched Reluctance Motor with Magnetic Ring Stator

技术领域technical field

本发明涉及一种圆筒形电机,尤其涉及一种导磁环定子圆筒形直线开关磁阻电机。The invention relates to a cylindrical motor, in particular to a cylindrical linear switched reluctance motor with a magnetic conduction ring stator.

背景技术Background technique

直线电机将电能直接转化为直线运动的机械能,不仅省略了中间传动机构,而且降低了系统损耗,非常适用于直线直驱式系统。The linear motor directly converts electrical energy into mechanical energy of linear motion, which not only omits the intermediate transmission mechanism, but also reduces system loss, and is very suitable for linear direct drive systems.

平板形直线电机为两端开断的开放式平板结构,电机铁心两侧存在横向开断,有明显的横向边缘效应,造成电机内磁场分布不连续,影响电机的运行性能。平板形直线电机的绕组方式与旋转电机类似,存在端部绕组,当铁心长度较长并采用分布式绕组形式时,绕组利用率低,铜耗增加,降低了电机的运行性能。平板形直线电机除了产生直线推进力之外,还会在定子和动子之间产生法向磁拉力,加重导轨负荷,降低导轨的使用寿命。The flat linear motor is an open flat structure with both ends broken. There are transverse breaks on both sides of the motor core, which has obvious lateral edge effects, resulting in discontinuous distribution of the magnetic field in the motor and affecting the operating performance of the motor. The winding mode of the flat linear motor is similar to that of the rotary motor, and there are end windings. When the length of the iron core is long and the distributed winding form is used, the utilization rate of the winding is low, the copper loss increases, and the operating performance of the motor is reduced. In addition to generating linear propulsion, the flat linear motor will also generate normal magnetic pulling force between the stator and the mover, which will increase the load on the guide rail and reduce the service life of the guide rail.

圆筒形直线电机的机械结构、工作原理和性能特点与平板形直线电机完全不相同,圆筒形直线电机为封闭的圆筒形机械结构,由于电机铁心是闭合的,没有横向开断,因此不存在横向边缘效应,电机内磁场沿圆周均匀连续分布,推进力密度高。圆筒形直线电机内定子槽为环形,电机绕组为同心绕组,没有端部绕组,绕组利用率高,运行时铜耗低,有利于提高电机效率。此外,由于圆筒形直线电机为封闭结构,电机内定动子之间的法向磁拉力相互抵消,当电枢绕组通入电流时,定子磁场和动子磁场通过相互作用产生轴向电磁推力,实现电能和机械动能的转化。The mechanical structure, working principle and performance characteristics of the cylindrical linear motor are completely different from those of the flat linear motor. The cylindrical linear motor has a closed cylindrical mechanical structure. There is no lateral edge effect, the magnetic field inside the motor is evenly and continuously distributed along the circumference, and the propulsion force density is high. The inner stator slot of the cylindrical linear motor is ring-shaped, the motor winding is concentric winding, there is no end winding, the utilization rate of the winding is high, and the copper consumption is low during operation, which is conducive to improving the efficiency of the motor. In addition, since the cylindrical linear motor is a closed structure, the normal magnetic pull between the stator and the mover in the motor cancels each other out. When the armature winding is fed with current, the stator magnetic field and the mover magnetic field interact to generate an axial electromagnetic thrust. Realize the conversion of electrical energy and mechanical kinetic energy.

由于工作原理和内在电磁场分布的不同,适用于平板形直线电机的技术方案不能直接应用于圆筒形直线电机中。与平板形直线电机相比,圆筒形直线电机具有以下显著优点:Due to the difference in working principle and internal electromagnetic field distribution, the technical solutions applicable to flat linear motors cannot be directly applied to cylindrical linear motors. Compared with flat linear motors, cylindrical linear motors have the following significant advantages:

1、电机结构简单,密封性能好,运行时不受离心力影响;1. The structure of the motor is simple, the sealing performance is good, and it is not affected by centrifugal force during operation;

2、电机内没有横向开断,磁路连续,没有横向边缘效应,运行性能好;2. There is no transverse breaking in the motor, the magnetic circuit is continuous, there is no transverse edge effect, and the operation performance is good;

3、绕组为同心盘式绕组,没有端部绕组,绕组利用率高;3. The winding is a concentric disc winding, without end winding, and the utilization rate of the winding is high;

4、电机为封闭的圆筒结构,有效克服法向磁拉力;4. The motor is a closed cylindrical structure, which can effectively overcome the normal magnetic pull;

5、电机密封性能好,与开放式的平板形直线电机相比,不易受到外界灰尘的干扰,运行稳定性好,维护成本低。5. The motor has good sealing performance. Compared with the open flat linear motor, it is not easily disturbed by external dust, has good running stability and low maintenance cost.

圆筒形直线开关磁阻电机制造成本低,运行可靠性高,具有在各种恶劣条件下运行的优势,维护成本低,整个系统效率高于圆筒形直线感应电动机。但由于磁阻转矩的特性,电机推进力密度较低,因此,提高圆筒形直线电机的推进力密度,是亟待解决的问题。另外,现有圆筒型直线开关磁阻电机存在动子轭部,电机动子重量大,绕组通电时只有一部分磁路被有效利用,电机铁磁材料利用率低,功率密度和推进力密度低。Cylindrical linear switched reluctance motors are low in manufacturing cost, high in operational reliability, have the advantage of operating under various harsh conditions, low in maintenance costs, and have higher overall system efficiency than cylindrical linear induction motors. However, due to the characteristics of the reluctance torque, the propulsive force density of the motor is low. Therefore, it is an urgent problem to be solved to improve the propulsive force density of the cylindrical linear motor. In addition, the existing cylindrical linear switched reluctance motor has a mover yoke, the motor mover is heavy, only a part of the magnetic circuit is effectively used when the winding is energized, the utilization rate of the ferromagnetic material of the motor is low, and the power density and propulsion density are low. .

在直线开关磁阻电机中,动子采用导磁环结构可以省去铁心轭部,减小动子质量,提高推进力密度,但对于轨道较长的直线驱动场合,通常将没有绕组的铁心一侧作为运行轨道,有绕组的一侧作为动子,目的是减小制造电机铜绕线的用量,降低成本。In the linear switched reluctance motor, the mover adopts the magnetic permeable ring structure, which can save the core yoke, reduce the mass of the mover, and increase the propulsion density. However, for linear drive applications with long tracks, usually the iron core without windings The side is used as a running track, and the side with windings is used as a mover. The purpose is to reduce the amount of copper windings used to manufacture motors and reduce costs.

本发明的工作原理:由于所述电机动子绕组为同心绕组,当动子绕组线圈通电时,同心线圈中将会产生磁通,所产生的磁通沿电机动子轴方向流动,由于定子导磁环由高导磁率材料制成,导磁率很高,当动子绕组所在环形槽的中心线与某个定子导磁环中心线对齐时,动子绕组所产生的磁通经由动子轴后,将沿电机径向分流,分别经过动子齿、空气隙、定子导磁环闭合,在此位置下,该动子绕组线圈产生的磁通对应的磁路磁阻最小,绕组交链的磁链最大;当该动子绕组所在环形动子槽中心线与定子两个导磁环之间的非导磁定子套筒中心线对齐时,此时该动子绕组产生的磁通经由动子轴后,将沿电机径向经过动子齿、空气隙和非导磁定子套筒闭合,由于非导磁定子套筒导磁率很低,该绕组线圈产生的磁通对应的磁路磁阻最大,绕组交链的磁链最小。根据磁阻最小原理,磁路磁阻的变化会产生推进力,当持续不断的给动子绕组线圈通电时,便可通过在定子和动子之间产生持续的推进力并将电能转换为机械动能。The working principle of the present invention: because the motor mover winding is a concentric winding, when the mover winding coil is energized, magnetic flux will be generated in the concentric coil, and the generated magnetic flux will flow along the direction of the motor mover axis. The magnetic ring is made of high magnetic permeability material, and the magnetic permeability is very high. When the center line of the annular groove where the mover winding is located is aligned with the center line of a stator magnetic ring, the magnetic flux generated by the mover winding passes through the mover shaft. , the flow will be shunted along the radial direction of the motor, respectively passing through the mover teeth, the air gap, and the stator magnetic ring to close. The chain is the largest; when the centerline of the annular mover slot where the mover winding is located is aligned with the centerline of the non-magnetic stator sleeve between the two magnetically permeable rings of the stator, the magnetic flux generated by the mover winding passes through the mover shaft Finally, close the mover teeth, the air gap and the non-magnetic stator sleeve along the radial direction of the motor. Since the magnetic permeability of the non-magnetic stator sleeve is very low, the magnetic flux generated by the winding coil corresponds to the largest reluctance of the magnetic circuit. The flux linkage of winding interlinkage is minimum. According to the principle of minimum reluctance, the change of reluctance in the magnetic circuit will generate propulsion. When the winding coil of the mover is continuously energized, it can generate continuous propulsion between the stator and the mover and convert the electrical energy into mechanical kinetic energy.

本发明的有益效果:Beneficial effects of the present invention:

本发明电机中的定子采用导磁环,当动子绕组线圈通电时,动子绕组线圈产生的磁通将经由动子绕组线圈所在环形动子槽两侧的动子齿和定子导磁环闭合,由于绕组产生的磁通与环形动子槽两侧的动子齿均产生交链,因此绕组能够交链更多的有效磁通,与现有圆筒形直线开关磁阻电机相比,本发明电机具有更高的推进力密度。由于本发明电机省去了定子轭部,降低了制造电机铁心材料的用量,提高了材料的利用率;每个定子槽内只安放有一套绕组,与现有直线开关磁阻电机相比,省去了相间绝缘,简化了电机制造工艺,提高了槽利用率;动子绕组为同心共轴绕组,围绕定子轴线缠绕,省去了绕组端部,提高了铜材料的利用率;采用圆筒形结构,密封性能好,结构简单可靠,功率密度高,能够满足高速往复驱动的直线运动场合。The stator in the motor of the present invention adopts a magnetic conduction ring. When the mover winding coil is energized, the magnetic flux generated by the mover winding coil will be closed by the mover teeth and the stator magnetic conduction ring on both sides of the annular mover slot where the mover winding coil is located. , since the magnetic flux generated by the windings interlinks with the mover teeth on both sides of the annular mover slot, so the windings can interlink more effective magnetic flux. Compared with the existing cylindrical linear switched reluctance motor, this Invention motors have higher propulsion density. Because the motor of the present invention omits the stator yoke, the consumption of the core material of the motor is reduced, and the utilization rate of the material is improved; only one set of windings is placed in each stator slot, compared with the existing linear switched reluctance motor, saving The interphase insulation is removed, which simplifies the motor manufacturing process and improves the utilization rate of the slot; the mover winding is a concentric coaxial winding, which is wound around the axis of the stator, which saves the winding end and improves the utilization rate of copper materials; adopts a cylindrical shape structure, good sealing performance, simple and reliable structure, high power density, and can meet the linear motion occasions of high-speed reciprocating drive.
