Abstract: A multi-phase electric motor is proposed that comprises a rotor and a stator. The rotor has a number of magnets directed towards the stator and the stator includes a plurality of phase windings directed towards the magnets. The phase windings are connected to control units that are adapted to selectively apply a current to the phase windings to induce an electromagnetic force which acts upon the magnets to effect a rotation of the rotor. The motor comprises at least two control units, each being configured to control the supply of current to three phase windings such that a different phase current is supplied to each of the three phase windings with a phase shift between said different phase currents being 120°, and wherein no two control units utilise the same current phase. By distributing current over at least six phases and utilising two or more control units operating as simple 3-phase motors, low voltage operation is enabled without the associated disadvantages of high winding currents, while control is simplified over conventional systems.
Abstract translation: 提出了一种包括转子和定子的多相电动机。 转子具有指向定子的多个磁体，并且定子包括指向磁体的多个相绕组。 相绕组连接到控制单元，控制单元适于选择性地向相绕组施加电流，以引起作用在磁体上的电磁力来实现转子的旋转。 电动机包括至少两个控制单元，每个控制单元被配置为控制到三相绕组的电流供应，使得不同的相电流被提供给三相绕组中的每一个，其中所述不同相电流之间的相移为120°， 并且其中没有两个控制单元利用相同的电流相位。 通过分配至少六相的电流并利用两个或更多个作为简单的三相电动机运行的控制单元，低压运行能够实现高绕组电流的相关缺点，而控制比传统系统简化。
