1. A control electronics system, comprising
a DC/DC converter (1),
control electronics (4) coupled to the DC/DC converter (1),
a power amplifier (5) coupled to the control electronics (4),
an electric motor (3) having three phases coupled to the power amplifier (5),
an electronic load (R), and
a switch(S) arranged to connect the electronic load (R) to the power amplifier (5), wherein
the control electronics (4) is configured to deactivate the DC/DC converter (1) in event of power failure and connect the electronic load (R) to the power amplifier (5) through the switch(S), ensuring required counter-torque.
