Abstract: A method for driving an inductive load (A, B, C) arranged in an electrical circuit (1 ) further comprising at least two switching elements (T 1 T 6 ) and a DC power source (3) having a set of terminals. The method comprises the steps of closing a switching element, thereby connecting the inductive load to the terminals, opening the switching element, thereby disconnecting the inductive load, closing a second switching element, thereby connecting the inductive load to a current sink in order to allow a demagnetisation current in the inductive load to decay, and opening the second switching element when the demagnetisation current has decayed to a minimum level. Using this method the demagnetisation current does not have to decay via a diode. Thereby energy is not dissipated in a diode, and the efficiency of the circuit is thereby improved. Furthermore, the requirements to the components of the electrical circuit are reduced, and it is thereby possible to use less expensive components.

Abstract: The invention relates to an electric motor, comprising a rotor (1). One side of said rotor (1) is mounted in a stator (3) by means of a bearing (2) and the rotor tapers away conically from said stator in an axial direction, forming an air gap (4) between the latter (3) and the rotor. The width of said gap increases in an axial direction, moving away from the bearing (2). The aim of the invention is to achieve improved operating efficiency using a conically designed rotor. To this end, the rotor (1) has a number of axially extending grooves (7) in a magnetically conductive material (5), in which electric conductors are placed and the difference between the maximum value and the minimum value of the thickness of a cover (8) of the grooves (7) through the magnetically conductive material of the rotor (1) in a radial direction between the end of a groove (9) lying at the outer radius and a peripheral surface (10) of the rotor (1), is less than in the case of a thickness of the cover (8) which continuously diminishes in an axial direction away from the bearing (2).
