The device has an electric drive motor e.g. spherical motor, and an electronic controlling unit that is divided into functional blocks. The functional blocks are arranged on two separated printed circuit boards (16, 22), where one of the functional blocks represents power supply part, which supplies small voltage as input voltage for another functional block. The former functional block includes a transformer or switching power supply. The latter functional block includes a micro electronics unit that is connected with stator coils of the drive motor for current feeding of the coils. |
