The disclosure relates to control electronics in a modular design, comprising an electronic base module and a plurality of functional modules, wherein: the base module provides at least one DC link voltage UZK at a voltage supply output for the voltage supply of the functional modules and the functional modules are electrically and mechanically connected to the base module and are supplied with the DC link voltage UZK by the base module; the base module and the functional modules each have a carrier having electronic components, the electronic components of the base module producing the DC link voltage UZK, at least one functional module being fastened to the carrier of the base module; and the electronic components of the base module and of the functional modules are arranged separate from one another by means of a thermal decoupling and/or an EMC shield.

Control electronics in modular design

A control circuit () for an electronically commutated, direct current motor (M) without a collector with a semiconductor end stage () which is controlled by an electronic commutation control () via a driver stage () 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 () 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 () deactivates the driver stage () and the second stall protection unit () shuts off the supply voltage (U) for the driver stage ().
