    摘要: A control circuit (1) for an electronically commutated, direct current motor (M) without a collector with a semiconductor end stage (2) which is controlled by an electronic commutation control (4) via a driver stage (6) for the time-offset control of the stator coils (U,V,W) of the motor (M) for the purpose of producing a magnetic rotating field for a rotor depending on the rotor rotation position. Two redundant stall protection units (10, 12) monitor the motor (M) during operation for rotation of the rotor, whereby in the case of a determined stall situation, the first stall protection unit (10) deactivates the driver stage (6) and the second stall protection unit (12) shuts off the supply voltage (UVCC) for the driver stage (6).

    摘要: The disclosure relates to an electronic control circuit for an electric device, in particular designed as a commutation electric system of an EC motor, having a plurality of power transistors which are controlled in an operating mode for controlling the device. An additional, similar, non-charged reference transistor in the operating mode of the power transistors is arranged or formed together with the power transistors on a common support or substrate. The circuit also comprises means for applying to the reference transistor and at least one power transistor, respectively one test flow in a test mode for measuring the respective associated saturation voltage and for evaluating saturation tension differences resulting from the measured saturation voltages of the reference transistors and the respective power transistors taking into account the temperature of the support/substrate produced during the measurement as the criterion for an aging process and an expected remaining service life of the power transistors. The disclosure also relates to a method for monitoring power transistors in said type of electronic control circuit with respect to the expected remaining service life thereof.
