摘要： The invention relates to a triggering device (1) for a thermal fuse, comprising an actuator (11), which is designed to trigger at a threshold temperature, and a conductive bridge element (6) that is attached and connected to multiple connector points (9) exclusively by means of detachable connecting elements (10) for current flow. According to the invention, the connecting elements (10) fully detach the bridge element (6) when a threshold temperature is reached or exceeded so that, in case the actuator (11) is triggered, the bridge element (6) is detached from the connecting elements (10) in order to interrupt the current flow.

摘要： Disclosed is a method for triggering an electric motor by means of a pulse width modulation signal that has a specific triggering frequency and a specific pulse duty factor. The electric motor is triggered via a supply voltage line according to the pulse duty factor. At least one electrical component is provided on the supply voltage line for low-pass filtering the voltage fluctuations caused by the pulse width modulation signal. The inventive method is characterized by the fact that the triggering frequency of the pulse width modulation signal is modified according to the pulse duty factor.

摘要： The invention relates to a circuit assembly for a motor vehicle. The circuit assembly comprises an electric motor. The electric motor comprises a control unit, wherein the control unit is designed to actuate the electric motor, in particular a stator of the electric motor, for rotating the rotor. According to the invention, the circuit assembly comprises a controllable switch with a control connection. The controllable switch is connected, in particular in a separable manner, on the input side to a battery potential of an on-board power supply system of the motor vehicle. The controllable switch is connected on the output side to the electric load, in particular the electric motor, preferably to the control unit of the electric motor. The control unit has a control input for receiving an activation signal for activating the load, in particular in the case of an electric motor for rotating a rotor of the electric motor. The control unit is connected to the control connection of the controllable switch and designed to apply a switch signal to the control connection to activate the load depending on the activation signal.

摘要： The invention relates to an electric motor having a stator and a rotor. The electric motor also comprises a controller, wherein the controller is connected to the stator and/or rotor, and is designed for applying current to the stator and/or rotor for rotating the rotor. According to the invention, the controller comprises a pulse width modulator designed for controlling a power output of the electric motor, in order to generate a predetermined number of different current application patterns. The current application patterns each represent a power output of the electric motor, and preferably comprise a time sequence of current pulses, each having a current pulse duration. The controller is designed for applying current to the electric motor according to at least two different current application patterns for actuating the electric motor during a time interval of actuation, such that a power output of the electric motor in the time-based average of the time interval of actuation, in particular from the beginning to the end of the time interval, is different from the power outputs represented by the current application patterns in the time interval of actuation.
