1. A motor apparatus for a switch drive of an electrical switch, the motor apparatus comprising:
an electric motor;
a controller for controlling said electric motor, said controller containing an energy supply for supplying electrical energy to said electric motor, said energy supply including:
a rectifier;
a voltage measurer for capturing a supply voltage or a rectifier output voltage of said rectifier;
a switching system for generating a drive voltage for said electric motor from the supply voltage or from the rectifier output voltage;
a supply controller for driving said switching system depending on the supply voltage or the rectifier output voltage, said supply controller having an input assembly, by means of said input assembly, input signals of at least one external device can be supplied or are supplied to said supply controller, the input signals of a limit switch for capturing an end position of the switch drive being supplied to said supply controller by means of said input assembly; and
a motor housing, which in addition to said electric motor houses at least a part of said energy supply and/or at least a part of said supply controller.
