Latest Patents
Heller's latest patents include a method of operating a vehicle and an electric powertrain. This innovative electric powertrain comprises a high voltage bus, an electric machine, and a traction inverter that is coupled between the high voltage bus and the electric machine. The electric voltage for the high voltage bus is generated with the electric machine and the traction inverter when the electric machine is driven mechanically. The generated electric voltage is limited and converted to a predetermined voltage lower than the limited voltage, which powers a unit of the vehicle, such as a cooling pump. Another significant patent is a method and device for calibrating a position sensor placed on a shaft of a permanent magnet synchronous motor. This method involves supplying a DC test current to the stator windings of the motor to generate a definite magnetic field. The motor speed caused by the DC test current is adjusted to zero by modifying the rotor position, and the position measured by the position sensor at zero motor speed relative to the magnetic field is used to calibrate the position sensor.
