摘要： A field-oriented control method for an electric drive comprising a plurality of electric motors, for implementing a tension mechanism, especially for load cable and/or gearing means, using measurements of a polyphase motor actual current. The measured values are transformed into a direct current component and a quadrature current component, based upon a magnetic rotor field or flux angle, in a rotor flux-based d,q coordinate system. The quadrature and direct current components from the actual current are subjected to a comparison with predetermined quadrature and direct current components of a current command value. The method has the following steps: a) two synchronous motors are used as electric motors; b) the magnet wheels or rotors of the two synchronous motors are rotated or oriented toward one another and are then mechanically coupled in such a way that between their magnetic flux linkages or other magnetic fluxes an angular offset is formed; c) the two synchronous motors are each supplied with or traversed by the same phase currents, from a shared power converter; d) for a pretension torque, a command or reference value is predetermined, and is superposed on a motor torque control value output by a controller, from which a quadrature current component for the current command value is derived; e) a direct current component for the current command value is derived from the predetermined tension torque control value with sign reversal.

摘要： A method and a control device for braking a variable speed vector controlled induction machine are driven by a pulse width modulation (PWM) inverter, in which the q-current component and the d-current component of the stator current are controlled independently from one another in accordance with a first reference signal (iq*) and a second reference signal (id*), respectively. For braking, high frequency components are superimposed on the second reference signal (id*), and the root-mean-square (rms) value (id rms) and the average value (id av) of the resultant second reference signal are controlled independently from one another such that the field requirements are met by the average value and high machine losses are produced by the rms value.
