摘要： An electric motor (19) comprises a first part (21) and a second part (23) which are rotatable with respect to each other about an axis of rotation (9). The first part comprises a foil-shaped insulating substrate (51) on which a plurality of series-connected spiral-shaped patterns (67, 67', 69, 69', 71, 71') of conductor tracks are provided. Said substrate is bent so as to form a circular-cylindrical body (29), which extends, seen in a direction parallel to the axis of rotation, between a first and a second imaginary end surface (59, 61), and which is mounted on a carrier (27) near the first end surface (59). The second part comprises a permanent magnet unit (73) for generating a magnetic field at the location of the conductor tracks. The first part is provided with connector means (79) for connecting the conductor tracks to an electrical energy source. According to the invention, the connector means (79) comprise a first connector element (91), which is provided on the substrate (51) between the first and the second end surfaces (59, 61) near the first end surface (59), and a second connector element (93), which is provided on the carrier (27) and is electrically connected to the first connector element. In a preferred embodiment, the first connector element comprises a number of additional conductor tracks (95, 97, 99, 101, 103, 105) which are provided on the substrate and extend substantially parallel to the first end surface. Thus, a simple and robust construction of the connector means is provided which is effectively protected against damage, which could be caused by inaccurate handling forces and movements during the manufacturing process of the motor. An electric motor (19) in accordance with the invention is used in a data storage unit (1) in accordance with the invention.

摘要： The invention relates to an electric drive system comprising a d.c. motor (2) with a control circuit provided with an electronic commutator (3). The invention is characterized in that it provides for a derivation of the adjustment signal (V_i_ref) originating from the induced motor voltage (E_sample) detected by a measuring device and from a reference value (V_i_av) which is used to regulate the speed of the d.c. motor. The invention is further characterized in that the derived adjustment signal (V_i_ref) is used to produce a substantially constant torque for said d.c.motor (2) by adjusting the motor currents (ia, ib,ic).

摘要： The invention relates to arrangements for the power supply of integrated circuits. Various solutions are proposed with a view to guaranteeing a power supply satisfying all the technical requirements with regard to ever greater permissible load jumps, greater permissible current change rates and ever tighter tolerances regarding the constancy of the supply voltage in question. In particular an arrangement with an integrated circuit (2) mounted on a bearing means (1) and a power supply module arrangement (3) is proposed, which is placed on the combination of bearing means (1) and integrated circuit (2) and whose base extends at least partially over the base of the integrated circuit (2) and/or all around the base of the integrated circuit (2).
