A method and apparatus for controlling an electric motor. A flow of an alternating current through stator coils in the electric motor is controlled based on a position of a rotor in the electric motor such that a repulsive force between a rotor and a stator coil in the stator coils occurs when the alternating current flows through the stator coil.

Systems and methods for mitigating constraints associated with wireless power transmission in applications where the position and orientation of the desired magnetic field changes over time, for example, because the position and orientation of the receiver being powered changes over time or because different receivers having different positions and orientations are being powered at different times. In accordance with some embodiments, the system employs a plurality of wireless power transmitters in a defined space, each transmitter consisting of individual coils oriented orthogonally relative to each other. Using field interference amongst these individual coils as well as amongst the transmitters they form, one can actively control the wireless power field intensity and orientation at any given point in the defined space. This allows for methods to steer the power transmission towards a specific target at a specific angle.

A method and apparatus for operating an electric motor is presented. A transmit magnetic field is received at a group of receive coils having a group of axes oriented substantially parallel to magnetic field lines from a transmit coil and having a group of resonant frequencies. A resonant frequency in the group of resonant frequencies is different from other receive coils in the group of receive coils. A receive magnetic field is generated at a receive coil in the group of receive coils having the resonant frequency when the transmit magnetic field has a selected frequency matching the resonant frequency. The receive magnetic field attracts a rotor in the electric motor.

The disclosure herein provides for interpreting and facilitating user input to virtual knobs on a touchscreen interface. Aspects of the disclosure provide for the interpretation of a contact with a virtual knob of a device represented on a touchscreen interface. In response to the contact, a state change associated with the virtual knob may be made, or an annular input icon displayed around the virtual knob. The annular input icon may guide an adjustment of the virtual knob.

A method and apparatus for controlling an electric motor. Power is transmitted to windings of the electric motor by wireless magnetic coupling between transmission coils and the windings.

Wirelessly powered electric motor

A method and apparatus for controlling a group of electric motors. A controller is configured to identify a group of switching frequencies for a desired signature for the group of electric motors. The controller is further configured to control switching of a current supplied to the group of electric motors with the group of switching frequencies for the desired signature identified.

Electric motor signature reduction system

A method and apparatus for controlling an electric motor. A switching frequency meeting a desired operating condition is identified from information relating to operation of the electric motor. A switching of a current supplied to the electric motor with the switching frequency identified is controlled.

Electric motor frequency modulation system

A method for controlling an electric motor. A desired speed is identified for the electric motor during operation of the electric motor. A voltage is identified to cause the electric motor to turn at the desired speed. The voltage is applied to the electric motor and actively controlled during operation of the electric motor.

Active voltage controller for an electric motor

A method and apparatus for operating an electric motor unit. Information is received from the electric motor unit over a wireless communications link between the controller and the electric motor unit. Commands are identified for the electric motor unit from the information received. The commands identified are sent to the electric motor unit over the wireless communications link.
