摘要： A permanent magnet motor is configured with selective variation of the radial distance between an interfacing pair of rotor permanent magnet and stator pole along the circumferential length of the pair. The effects of cogging torque on the overall torque signature can be controlled by setting an appropriate air gap variation profile. The stator pole and rotor magnet surfaces may be sloped with respect to each other, the angle therebetween being selected to obtain desired cogging torque compensation. Other air gap variation profiles may include provision of concave surfaces, the degree of concavity being selectable.

摘要： Rotary permanent magnet motors have salient stator poles with non-uniform pole thickness in the radial direction for compensating effects of cogging torque. Pole base portions terminate at pole shoes at the radial air gap. The pole shoes extend in the circumferential direction from the bulkier base portions. Variation of the thickness of the pole shoe changes the concentration of the effective flux at the point of coupling between the stator poles and the permanent magnet pole shoes. As there is no change in the active interfacing area of the pole shoes a uniform air gap is maintained. The torque signature for each stator pole/rotor permanent magnet interface can be selectively changed to smooth motor operation by configuring the stator pole shoe thickness to vary along its circumferential extent as appropriate. Pole shoes may have tapered leading or trailing edges with respect to a pole base to change the effective flux density in the air gap at a specific pitch of rotation. Additionally, the pole shoe may be shifted off center with respect to the pole base.
摘要翻译：旋转永磁电机具有在径向方向上具有不均匀极厚度的凸极定子极，用于补偿齿槽转矩的影响。极基部分在径向气隙处终止于极靴。极靴从较大的基部向圆周方向延伸。极靴厚度的变化会改变定子极与永磁铁杆之间的耦合点处的有效通量的浓度。由于极靴的主动接口区域没有变化，因此保持均匀的气隙。可以选择性地改变每个定子极/转子永磁体接口的扭矩特征，以便通过使定子极靴厚度在其圆周范围内适当地变化来平滑电机操作。杆鞋可以相对于杆座具有锥形的前缘或后缘，以在特定的旋转间距改变气隙中的有效通量密度。此外，极靴可以相对于杆座偏离中心。

摘要： A rotary electric motor has a stator (30) with a plurality of separate and ferromagnetically isolated electromagnet core segments (32) disposed coaxially about an axis of rotation. The core segments (32) are supported by a non-ferromagnetic structure.(50) Each core segment (32) has at least three poles aligned in a direction parallel to the axis. Windings are formed on portions linking the poles so that, when energized, the center pole forms a magnetic polarity opposite to the magnetic polarity of the other poles. The rotor (20) comprises a plurality of axial rows of permanent magnets disposed circumferentially along the air gap. Each axial row of rotor magnets comprises a center permanent magnet (22) of one magnetic polarity and, at each axial side thereof, a permanent magnet (23, 24) of a magnetic polarity opposite to the polarity of the center magnet.

摘要： Thermal management of an electric machine is implemented by selecting a stator core configuration with the machine application and determining the minimum heat dissipation necessary to maintain the temperature of the core segment configuration at peak excitation within acceptable limits. A core model is used to ascertain thermal distribution at peak excitation. Therefore, a pattern in the selected core segment configuration is established for placement of at least one heat pipe for removing heat from the core. Heat pipes are located at high thermal points in the core segment and oriented in alignment with mapped lines of flux. By placing the heat pipe either at the center of the core or at a recessed boundary layer between the core and winding, the heat pipe can capture and conduct excess heat away from the heat generating areas of the core, thus maintaining the core and the excitation windings at desired temperature.

摘要： A control system for a multiphase permanent magnet motor compensates for physical variations among individual motor phase circuit elements. The control system successively develops a control voltage for switched energization of the motor phase windings that is closely matched with particular parameters of the corresponding windings. The system can be applied to a motor in which each stator phase component comprises a ferromagnetically isolated stator electromagnet, the electromagnet core elements being separated from direct contact with each other and formed with separate phase windings. A digital signal processor may be utilized that applies an algorithm incorporating the parameters as constant values, the parameters for a particular phase being accessed for generating the appropriate control signals for energizing that phase.
