  • Patent number: 10063165
    Abstract: An electric motor is connected to a voltage source via a drive circuit and, between the drive circuit and the voltage source, the operating switch is arranged for the switching of the supply voltage (U) of the voltage source as the input voltage (UE) on the drive circuit. Following the switch-out of the electric motor, the input voltage (UE) on the drive circuit is monitored and a gradient of a rising voltage ramp (dU/dt) of the input voltage (UE) is determined. The gradient of the rising voltage ramp (dU/dt) of the input voltage (UE) thus determined is compared with a predefined limiting value and, in the event of an overshoot of the predefined limiting value, the operating switch is detected as closed, and the electric motor is restarted via the drive circuit.

  • Patent number: 8037858
    Abstract: A method for controlling the start-up phase of a motor vehicle driven by an internal combustion engine (12) wherein the internal combustion engines (12) is started by an electrical machine (16) that can be operated as a motor, a preferably automatically atuatable clutch (50) being located in the drive train (11) between the internal combustion engine (12) and the electrical machine (16). A faster start-up response can be achieved if the internal combustion engine (12) is driven by the electrical machine (16) when the clutch (50) is engaged during start-up, and if the clutch capacitance (MK) is reduced according to a defined parameter, preferably the engine speed, the time or the torque (ME) of the electrical machine (16) or similar.

  • Publication number: 20110215575
    Abstract: An electrical generator utilizing two internal combustion engine having an expanded range of power output is disclosed. A primary internal combustion engine is coupled to the magnet rotor assembly. The primary engine is operated solely in a lower power range. A secondary engine, coupled to a coil assembly is locked in place in such lower power range to make the coil assembly stationary. In a higher power range, that overlaps the lower power range, the secondary engine is unlocked and operated to rotate in a counter-rotating direction with respect to the first engine. The secondary engine can be started by operating the generator (consisting of the magnet rotor assembly and the coil assembly) as a motor by appropriate application of current.

  • Publication number: 20110101693
    Abstract: A starter generator has an electric rotating machine having a rotating shaft and designed to carry two reverse operations—motor and generator. A first clutch is connected between the rotating machine and the first rotating shaft for transmitting rotations of the rotating machine to the first rotating shaft. A second clutch is connected between the rotating machine and the second rotating shaft for transmitting rotations of the second rotating shaft to the rotating machine. A continuously variable transmission is provided for changing the number of rotations transmitted from the second rotating shaft to the rotating machine. The rotating machine is supplied with electric power to rotate the rotating shaft, or the number of rotations of the rotating shaft is kept constant by controlling a transmission ratio of the continuously variable transmission.
