摘要: A circuit arrangement comprises a circuit board (10), a semi-conductor (12) provided on a first side of the circuit board, and a heat sink (15) provided on a second side of the circuit board opposite to the first side and in heat transferring contact with the power semi-conductor. A heat conductive element (13) is provided in a hole (10a) in the circuit board, wherein the heat conductive element is positioned in heat transferring contact with both the semi-conductor and the heat sink for transfer of heat generated by the semi-conductor to the heat sink. A circuit arrangement is provided, wherein the provision of a low thermal resistance path through the circuit board by means of heat conductive elements provides a compact circuit arrangement well suited for assembly by means of an automated surface mounting process.

摘要: An induction motor comprises a stator (10) and a rotor (20), which includes material essentially blocking magnetic flux at high frequencies. A difference in number of stator slots and rotor slots is chosen so that the inductance of a winding provided in a stator slot is different from the inductance of a winding provided in another stator slot. A sense means, such as stator winding or separate sense winding, is provided in at least one of the stator slots and the sense means is arranged to allow measuring of the inductance thereof. The sense means constitutes an integrated sensor, which is both inexpensive and reliable. A method of sensing the rotor position and/or speed of an induction motor is also described.
