A method for improving the availability of an electromechanical actuator of an electromechanical or electrohydraulic brake system in a motor vehicle, including electronic motor regulation functioning in a non-restricted operating mode (normal operation) for a field-commutated electric motor actuated by pulse width modulation. An electronic device having a setpoint value interface (1) for presetting setpoint variables and parameters, a module for calculating pulse width modulation switching times (4), a module for dead time compensation (5), a power electronics module (6) for actuating an electric motor (7) actuated on three phases, including a module for setpoint current determination (2) which is electrically connected to the field-oriented current controller (3) and receives, via this connection, setpoint current values (Id_set, Iq_set) calculated using various state and/or estimated variables and stored parameters from the module for setpoint current determination.
