<p>The machine has a drive unit (1) e.g. spindle unit, with an electronic unit (6) to operate an electric motor e.g. brushless direct current electric motor (10). A contactless power supply unit (17) transfers power from an alternating current supply system (10) to the motor. The supply unit has primary and secondary sides (3, 4) with primary and secondary windings (12, 16). The sides form current flows, which are galvanically separated from each other and which are inductively influenced. The side (3) is assigned to the system (10) and the side (4) is provided as a component of the drive unit.</p> |
