摘要： A method for positioning a brushless electric drive comprising a stator that has at least one phase winding to which a voltage signal can be applied, and a rotor equipped with magnetic poles. In the method, a voltage signal is applied to the at least one phase winding, the voltage signal generates a magnetic field as a result of the current flowing in the phase winding. The magnetic field putting the rotor into alignment, and as long as the rotor is in motion, the voltage signal is modified in accordance with the intensity of the current induced in the at least one phase winding by the moving rotor, in such a way that the induced current is increased.

摘要： A method for operating a brushless, rotating electrical machine, including at least three phase windings, each of which has a first phase winding terminal and a second phase winding terminal. The phase windings are connected to each other, in particular the particular second phase winding terminals are connected to a shared star point, and phase-width-modulated voltage signals being applied separately to each individual phase winding, and at least one selected phase winding being at least temporarily connected to a constant electrical potential. To minimize switching operations and to reduce the alternating current component of the current source, the pulses of the pulse-width-modulated signals applied to the remaining phase windings are at least temporarily phase-shifted with respect to each other during the period in which the selected phase winding is connected to a constant electrical potential.

摘要： A method for determining the position of an at least two-phase, in particular three-phase bmshless electric drive comprising at least two phase windings, each of which has a first and a second terminal, a second terminal of a first phase winding being electrically connected to the first terminal of a second phase winding at a common connecting terminal. In order to be able to reliably determine the position of the electric drive even at low speeds, a voltage pulse is applied between the first terminal of the first phase winding and the second terminal of the second phase winding, the resulting voltage at the connecting terminal or at a third phase winding connected thereto is detected and the voltage ratio between the first phase winding and the second phase winding is determined therefrom, and the ratio between the variable inductances is determined from said voltage ratio.
