本文介绍了应用于变速空调的双转子、径向磁通和永磁无刷直流电机的不同布置。在传统空调中，通常使用两台适当额定值的电机分别驱动冷凝器和蒸发器。或者，可以采用具有两个输出轴的电机，这里对此进行研究。该电机具有内转子和外转子，定子位于其间，定子环形缠绕或轴向缠绕，具有内、外开槽定子表面。两个转子的功率分配是为了满足冷凝器和蒸发器的要求而设计的。采用有限元分析 (FEA) 来验证设计。制作并测试原型以评估性能。研究替代绕组以评估转子解耦的可能性，以便它们独立运行。在最后一节中，提出了一种新颖的布置，其中一个三相绕组组和一个两相绕组组（均为环形）缠绕在同一定子上，以控制两个不同极数的转子。两个绕组组可以是双线的或共用同一组相绕组。这种设计简化了绕组（因为它是环形的）并减少了铜损或所需的铜量。该设计使用 FEA 解决方案进行了测试，初步结果表明该机器可以成功运行。
This paper describes different arrangements for a dual-rotor, radial-flux, and permanent-magnet brushless dc motor for application to variable-speed air conditioners. In conventional air conditioners, two motors of appropriate ratings are usually used to drive the condenser and evaporator separately. Alternatively, a motor with two output shafts may be employed, and this is studied here. The motor has inner and outer rotors with a stator in between which is toroidally wound or axially wound with inner and outer slotted stator surfaces. The power sharing on the two rotors is designed to meet the requirement of the condenser and evaporator. Finite element analysis (FEA) is employed to verify the designs. A prototype is made and tested to evaluate the performance. Alternative windings are investigated to assess the possibilities of decoupling the rotors so that they run independently. In the final section, a new and novel arrangement is proposed, where one three-phase winding set and one two-phase winding set (both toroidal) are wound on the same stator to control two rotors of different pole numbers. The two winding sets can be bifilar or share the same set of phase windings. This design simplifies the winding (because it is toroidal) and reduces the copper loss or amount of copper required. The design is tested using FEA solutions, and the initial results indicate that this machine could operate successfully.
