Abstract: A stator segment for a linear motor-based transport system is developed to the effect that a transmitter for cyclic transmission of a control data record in a first clock cycle also transmits, in addition to transmitting the control data record, a position value in a clock-synchronized manner, wherein a plurality of positions are available as a sequence with a quantity of elements and an element with an index corresponds to a position, where the transmitter unit is configured such that, upon every first clock cycle, the index is incremented commencing from a starting value and an element is transmitted after the control data record, where the transmitter unit is furthermore configured to transmit all elements in one transmission interval, and where the transmission interval corresponds to a multiple of the first clock cycle.

Abstract: A first active part of a poly-phase electric machine is connected to a converter having a control facility. The control facility updates a base commutation angle using the target speed value and determines direct-axis and quadrature-axis component values of currents and a commutation angle supplied to the machine. Target and component quadrature-axis values are provided to a quadrature-axis portion of a current controller that determines a target value of the quadrature-axis voltage component. Target and component current values are supplied to a direct-axis portion of the current controller, which determines a target value of the direct-axis voltage component therefrom. The target value of the direct-axis and quadrature-axis voltage components and the commutation angle are used to determine the target output voltages provided to the converter. A damping commutation angle determined using target values of the quadrature-axis and direct axis voltage components is used to adjust the of the voltage.
