摘要： The invention implements a variation of the electrical transverse flux machine (motor or generator) that employs ferromagnetic excitation elements mostly located on the stator rather on the rotor. The excitation elements are employed in nearly-complete magnetic circuits that are periodically completed by the movement of the rotor. The varying flux that is thus generated is used to cause an EMF in windings, for the case of generators, or for the case of motors, appropriate EMF is used to cause varying flux that in turn causes rotation of the motor.

摘要： The embodiments relates to a stator used in resolvers, in which multiple slots are formed at constant intervals in the circumferential direction and have an excitation coil, a first output coil, and a second output coil are respectively wound around the multiple slots. The excitation coil is wound by a number of windings that is changed on the basis of a sinusoidal wave in accordance with the order of the multiple slots in the circumferential direction. After the first output coil is wound by a number of windings resulting from the division of the total number of windings by a constant ratio, the second output coil is wound, and then the rest of the first output coil is wound.

摘要： Disclosed is a hybrid pole bearingless switched reluctance motor (BLSRM). The BLSRM includes a stator provided with windings, a rotor rotating about an axis when current is conducted to the windings. The rotor includes a plurality of rotor poles extending radially outward, and the stator includes a plurality of stator poles extending radially inward. The windings include suspending windings to generate radial force for the rotor and torque windings to generate torque. The suspending windings are mutually separated from the torque windings. Through the use of the hybrid pole BLSRM, a stator pole generating the radial force can be controlled independently from the stator pole generating the torque by separately arranging the stator pole generating the radial force and the stator pole generating torque based on the analysis of radial force and torque characteristics according to the position of the stator poles.

摘要： An electrical machine with torque limitation which is only slightly larger structurally than an identical machine without torque limitation and is thus as compact as possible has a stator with windings and a rotor supported movably relative to the stator, recesses distributed over the circumference and extending axially are present on the rotor surface, and a driver, located coaxially relative to the rotor and extending axially, is located in the air gap between the rotor and the stator, and exciter magnets on the upper driver face toward the stator and driver magnets on the inner driver face toward the rotor are located in such a way that upon rotation of the driver, the rotor is likewise capable of being set into rotation as a result of the rotary field generated by the windings and by the driver magnets.

摘要： In order to improve the torque per weight ratio in electrical machines for a lower price it is proposed to use a segmented stator design. The segmented stator design is based on general E shaped cores traditionally used for single-phased transformers and inductors, The E-cores has a coil around the centered leg and is assembled parallel to the rotor axis, which means it will function with the transverse flux principle. A radial flux principle can also be performed with the E-cores if the E-cores are divided into two U-sections with a full pitch winding in between them. A clear extra advantage with the E-cores is short flux paths meaning less steel has to be magnetised. For a low volume production standard E-cores can be used making the investment in production facilities smaller. The E-core machines using the transverse principle can have different pole-shapes such the normal force between the rotor and stator are significantly reduced. This makes unequal designs like a 3 stator- and 2 rotor-pole design practical possible.
摘要翻译：为了以更低的价格提高电机中的重量比的扭矩，提出使用分段定子设计。分段定子设计基于传统上用于单相变压器和电感器的通用E型磁芯.E型磁芯围绕中心腿具有线圈，并且与转子轴线平行组装，这意味着它将与横向磁通原理。如果E型芯分为两个U形截面，则它们之间也可以采用径向通量原理，其中E型芯分为两个U形截面。 E芯的明显优势是短路径意味着较少的钢必须被磁化。对于小批量生产标准，可以使用电子核心，使生产设施的投资更小。使用横向原理的E型机器可以具有不同的极点形状，使得转子和定子之间的法向力显着减小。这使得不同于3个定子和2个转子极设计的设计实际上是可行的。

摘要： A motor has a rotatably supported rotor core and permanent magnets disposed at equal intervals at a plurality of positions in a circumferential direction of the rotor core. The rotor core has projecting poles formed at equal intervals at a center between each permanent magnet. Furthermore, an opening angle center line of each projecting pole conforms to a center line of an angle created by each opening angle center line of two adjacent permanent magnets. Additionally, each projecting pole is shaped asymmetrical to a line connecting a center of the projecting pole in the rotational direction of the rotor core and an axis center of the rotor core.

摘要： A control circuit for an inductive load, such as a phase winding of a reluctance motor, includes a boost flyback converter. The controller includes a dc link capacitor switchable across the load by means of a control switch and a suppressor switch for controlling the application of rectified current to the dc link capacitor. The suppressor switch is operated independently of the control switch in order to control the rectified current so that it follows the sinusoidal input voltage waveform. By this technique, the harmonics generated by switching the rectified input current are substantially suppressed.

摘要： A rotary electric motor has a stator core (1) with salient poles (4, 3), some of them ferromagnetic and some of them permanent-magnetic, which are spaced-apart and which are all simultaneously magnetizable by means of a magnetizing winding (5A, 5B). The rotor core has either reluctance poles (7) with intervening pole gaps and constant pole pitch, or permanent-magnetic poles (10) with constant pole pitch and without intervening pole gaps, alternating poles being of opposite polarities. Each reluctance pole (7) or permanent-magnetic pole (10) has a width which over a portion of the pole corresponds to respectively one-half of or the full pole pitch and is smaller over the remaining portion so that each pole (7 or 10) has a part (7B or 10A) which projects in a direction common to all poles. The ferromagnetic and permanent-magnetic poles (3, 4) of the stator (1) have a width corresponding to the width of the narrower portion of the poles (7 or 10) of the rotor (2). The number of permanent-magnetic poles (3) and, optionally, also the number of ferromagnetic poles (4) of the stator (1) is smaller than the number of reluctance poles (7) or permanent-magnetic poles (10) of the rotor (2), the positioning of the poles being such that when the motor is running, all ferromagnetic stator poles (4) will be simultaneously positioned opposite respective rotor poles (7 or 10) and all permanent-magnetic stator poles (30 likewise are simultaneously positioned opposite respective rotor poles (7 or 10).
