摘要： An electronic control device for an electric motor (10), particularly an electrically commutated (EC) motor, whose motor windings (11 to 13), in order to control the winding current, are connected in series with respective control transistors (15 to 17) whose control connections are charged by control pulses which are triggered by commutation signals and which have a predeterminable pulse-duty factor (block control). At the same time, the control device varies the amplitudes of the control pulses to control and permit the operation of the control transistors (15 to 17) in their amplifying range (linear control). Block control dominates in the upper rpm range in order to improve efficiency with respect to pure linear control, and linear control dominates in the lower rpm range in order to prevent severe current peaks, and hence an increased noise development that would occur with pure block control.
摘要翻译：用于电动机（10）的电子控制装置，特别是电动换向（EC）电动机，其电动机绕组（11至13），以便控制绕组电流，与各个控制晶体管（15至17）串联连接），其控制连接由由换向信号触发且具有可预定的脉冲占空系数（块控制）的控制脉冲充电。同时，控制装置改变控制脉冲的幅度以控制并允许控制晶体管（15至17）在其放大范围（线性控制）中的操作。块控制在上转速范围内占主导地位，以提高纯线性控制的效率，并且线性控制在较低的转速范围内占主导地位，以便防止严重的电流峰值，从而增加纯块控制所产生的噪声发展。
