摘要：The device has an electric drive motor e.g. spherical motor, and an electroniccontrolling unit that is divided into functional blocks. The functional blocks are arrangedon two separated printed circuit boards (16, 22), where one of the functional blocksrepresents power supply part, which supplies small voltage as input voltage for another
functional block. The former functional block includes a transformer or switching powersupply. The latter functional block includes a micro electronics unit that is connected withstator coils of the drive motor for current feeding of the coils.
