Abstract
An electric motor includes a motor winding interconnection for operating an electrosurgical instrument with exactly one motor platform that is designed to operate the motor at a first operating voltage and a second operating voltage different from the first operating voltage. The motor platform includes a circuit, preferably a delta circuit or a star circuit, formed in each case by three phases with a respective phase coil. At least one phase coil is formed from N>1 interconnected individual coils. At the first operating voltage, the N individual coils of each phase coil are connected in parallel. At the second operating voltage, the N individual coils of each phase coil are connected in series. At least one short-circuiting mechanism per phase coil switches over between the first and second operating voltage.
