    摘要: A rotor includes a rotor core formed of webs defining a layout of the magnets in the rotor core. The rotor core has at least one layer of magnets forming a plurality of poles. Each pole includes a plurality of slots for holding a magnet, at least two ribs comprising web portions between the centerline slot and each wing slot, and a plurality of magnets arranged in corresponding slots. The slots have at least a centerline slot and two angled wing slots extending from a position at or around respective ends of the centerline slot towards an outer circumference of the rotor core. The wing slots may taper from a position at or around respective ends of the centerline slot towards an outer circumference of the rotor core.

    摘要: The invention refers to a computer-implemented method for determining a parameter of a field-oriented control, FOC, model for an electric power unit, the electric power unit comprising a three-phase electric motor and an inverter drive for driving the electric motor, the method comprising the steps of: sending a control signal to the inverter drive; applying a predefined electric voltage to at least two of the phases of the electric motor by the inverter drive in response to the control signal; measuring an electric current that flows in the at least two phases of the electric motor in response to the applied electric voltage; and determining the parameter of the control model for the electric power unit using a value of the applied predefined electric voltage and a value of the measured electric current. Further, a corresponding apparatus for determining a parameter of a control model for an electric power unit is provided. The accuracy of the parameters determined by the method according to the invention is based on the precision of the applied voltages and for this reason it is necessary to foresee a hardware and software function to obtain this precision.

    摘要: This invention relates to sensorless control (i.e. without encoder at the motor shaft) of an induction motor (AC asynchronous motor). In particular, the invention comprises a method for a direct measurement of the electromotive forces (EMF) at the stator of the motor to allow for the regulation of the speed of the motor in a wide range, including the very low frequency range. The method provides the accurate measurement of the EMF at the stator in such a way that the direct control of an induction motor will get simpler, in terms of less calculation and, overall, in terms of accuracy and consistancy of the results, thanks to the availability of a direct measurement of the EMF instead of a bare estimation thereof. To enable the direct measurement, the employment of at least two sensor windings (sensor coils) is needed each one mutually coupled with the stator phase of the motor.
