    摘要: A method of controlling an electrical machine that includes exciting a phase winding with a supply voltage, and freewheeling the phase winding when current in the phase winding exceeds a threshold. The threshold is then adjusted in response to changes in the supply voltage and/or the speed of the electrical machine. Additionally, a control system that implements the method and an electrical machine comprising the control system are described.

    摘要: A stator comprising a plurality of stator elements, each stator element comprising a core and a coil wound about the core. The coil of at least one stator element is wound at angle such that the coil is sheared towards an adjacent stator element so as to reduce magnetic flux leakage between the two elements.
