Abstract: A brushless DC motor having a plurality of electrical windings and a control circuit operatively connected thereto. The control circuit includes a plurality of switches configured for a time-dependent application of an electrical voltage from an external voltage supply to the windings. A measuring device is also provided for generating an electrical signal depending on the current flow IB from the external voltage supply through the control circuit. An overcurrent fuse is further provided for protecting the control circuit and the windings. In order to achieve particularly high integration of the control circuit, the invention proposes supplying a voltage drop across the overcurrent fuse to the measuring device as an input value.

Abstract: A method for actuating a BLDC motor for reducing the current ripple in an intermediate circuit capacitor includes means for monitoring pulse width modulated signals (PWMU, PWMV, PWMW) for each motor phase (U, V, W), which add motor phase currents Iu, Iv, Iw) of two adjacent phases in a first step, and add the respective pulse width modulated signals (PWMU, PWMV, PWMW) if the added currents value is over zero, and shift the phase of at least one pulse width modulated signal (PWMU, PWMV, PWMW) in the time slot T if the added signals result is greater than 1.

Abstract: A system and a motor controller for a motor vehicle, the motor controller having electronics configured to bring about the energization of the windings of an electric motor. A clock generator is configured to send a clock signal which controls the processes of the electronics. The motor controller is operatively connected to a slave of a bus system in order to transmit and/or receive signals, and the clock of a clock signal being provided by the bus master is used via the slave to synchronize the clock generated by the clock generator of the motor controller.

Abstract: A system for providing a set point increase for a vehicle combustion engine includes a control that is operable to control vehicle secondary systems to control the power consumption of the vehicle secondary systems to increase a mechanical load to the vehicle combustion engine. The load increase of the combustion engine may be for increasing the lost heat, which enhances the filtering of exhaust gases of the vehicle combustion engine. The lost heat may be utilized to increase the heat of a carbon particle filter, through which exhaust gases flow.
