摘要： A two-phase stepper motor (91) with a permanent magnet (PM) rotor (41, 93) and a modified hybrid-type stator (61, 92) is provided. The modified hybrid stator can be manufactured for smaller motor sizes because it employs shoeless, straight stator poles (64) without stator teeth and with bobbin coils (71) that are prewound outside the motor and easily inserted over each of the stator poles. Each bobbin may be an elongated continuous belt (73) of insulative material with a hollow interior that forms a sleeve (75) that fits around its corresponding stator pole (64). Conductive wire (79) wound around the sleeve forms the stator coils. Edges of the sleeve may have exterior flanges (77, 78) at radially inner and outer ends of the stator pole to hold windings in place and keep the sleeve from bowing outward.

摘要： The present invention is a three-phase axial stepper motor with DC excitation that enables rotation in the pre-determined direction as a response to the successively generated electrical signals, whereby the invention avoids the use of permanent magnets on the rotor and nevertheless achieves torque values that are higher than those that can be produced by variable-reluctance stepper motors or achieves motor characteristics that are similar to those of axial permanent magnet motors. The rotation itself depends on the control of the stator poles (6) and the design of the three-tooth symmetrical rotor plates (1A,1B), which are interconnected by a ferromagnetic shaft (9), onto which a DC excitation winding (5) of the rotor (2) is mounted axially, whereby the excitation winding is stationary and - owing to its construction - enables there to be no mechanical connection between the ferromagnetic rotor of the motor (2) and the excitation winding (5) of the rotor (2), on which the DC excitation causes all the teeth of the upper rotor plate (1A) to become polarized as the N-pole and all teeth of the lower rotor plate (1B) to become polarized as the S-pole.
摘要翻译：本发明是一种具有DC激励的三相轴向步进电动机，其能够响应于连续生成的电信号而能够以预定方向旋转，由此本发明避免了在转子上使用永磁体，并且仍然实现转矩值高于由可变磁阻步进电机产生的电动机或实现与轴向永磁电动机类似的电动机特性。旋转本身取决于定子极（6）的控制和通过铁磁轴（9）互连的三齿对称转子板（1A，1B）的设计，其中DC励磁绕组（5）转子（2）的轴向安装，由此励磁绕组是静止的，并且由于其结构，使得在马达（2）的铁磁转子和励磁绕组（5）的铁磁转子之间不存在机械连接转子（2），其中DC激励使得上转子板（1A）的所有齿变得极化，因为下转子板（1B）的N极和所有齿都被极化为S极。

摘要： A discoidal dynamo-electric machine has a discoidal stator (303) carrying a plurality of meandering copper windings (301, 302) embedded in a substrate having a magnetic permeability of less than 20, relative to air, and a discoidal rotor (305) mounted on a central shaft so that the rotor can be positioned close to and rotates in a plane parallel to that of the stator (303). The rotor has a circular array of permanent magnets (307, 308) mounted on a backing plate of mild steel, the magnets being strontium-ferrite magnets and each has a trapezoidal or sector shape, with the magnets being closely spaced around the rotor to provide a series of closely apposed and alternating permanent magnetic poles.
