摘要： The invention relates to a fan arrangement and a method for operation thereof, comprising a control module (1) for controlling two circuit breakers, two circuit breakers (3, 4), two electric motors (5, 6) which have their operating voltage UB supplied to them via the circuit breakers (3, 4), and at least one temperature sensor (8) on a board (2) on which the circuit breakers (3, 4) are located, with the control module (1) having means for evaluation of a signal TNTC from the temperature sensor (8) and for setting the duty ratios TV1, TV2 of pulsed control voltages at the circuit breakers (3, 4), taking account of this signal TNTC as well as a requested fan power, such that no power loss PV greater than a predetermined value occurs in any power component (3, 4, 7).

摘要： The invention relates to a method for detecting blocking or sluggishness (M
1 , M
3 ) of a DC motor (2). The method comprises the following steps: applying a voltage pulse (U
v,t = O
s ) to the DC motor (2); monitoring a motor current (I
Motor ) flowing through the DC motor (2); detecting a maximum value of the motor current (I­
Motor ) following the application of the voltage pulse; checking whether a change in the motor current (I
Motor ) after reaching the maximum value exceeds a specific amount; signalling the blocking or the sluggishness (M
1 , M
3 ) of the DC motor (2) if the change in the motor current (I
Motor ) after reaching the maximum value exceeds the specific amount.

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.

摘要： The invention relates to an electronically commutable motor whose excitation coils can be controlled in a successive manner at a commutation frequency via semi-conductor output stages and can be connected to a direct power supply voltage and disconnected therefrom, whereby said control signals are pulsed and undergo pulse-width modulation. Noise produced when the electrical supply is connected to and disconnected from the excitation coils is minimized by flattening out the rising or falling edge of the current flowing into the excitation coils, by increasing the pulse width ratio in the rising edges of the control signals according to a pre-defined or pre-definable set value for the revolution speed or output of said motor from a low initial value to an operating value assigned to the set point value, and by reducing the pulse width rates, starting from the operating value in the falling edges of the control signals to a low final cut off value according to the actual value of the revolution speed or output of said motor before reaching zero.
