A method and an apparatus for processing a web of a flexible material, in particular paper, moved along a direction of motion of the material, in which individual sections are produced from the material web by a first double-carriage linear motor and a second double-carriage linear motor, which are arranged parallel to the direction of motion of the material and each have a first carriage and a second carriage in the direction of motion of the material. Each of the carriages has a driving element.

Method and apparatus for processing a material web

Procedure for determining the electrical drive speed (&#x3c9;) and/or position (&#x3c6;) in a permanent magnet rotor of a brushless electrical linear or rotary motor from a measurement of a multi-phase stator current (i,i). Speed is determined using a mathematical motor model (). From the influence of a rotor reverse EMK that affects the stator current (i,i) conclusions are made about the rotor speed (&#x3c9;) and/or position (&#x3c6;) and an appropriate model speed value () is generated.

Procedure for estimating the electrical drive speed and position of a permanent magnet rotor of a brushless electrical linear or rotating motor, especially for a drive control circuit, using multi-phase current measurements on the motor, whose measurement values, depending on the estimated position, are transformed into a rotor-related d,q reference frame i.e. into a direct current vector component and a quadrature current vector component, and the direct and quadrature vector components of current and a voltage, together with the estimated speed, are fed as input variables to a mathematical motor model, and the motor model generates a first output variable and a second output variable, whereby the first output variable in the d,q reference frame corresponds to the d or direct vector component as well as to a position estimation error, and the second output variable in the d,q reference frame corresponds to the q or quadrature component as well as to a speed estimation error, and the two output variables are fed to a tracking controller for estimating and outputting the position and/or speed, whereby from the motor model a third output variable is computed, by

An electrical drive system for angular positioning of one or several rotating and/or tilting machine components and equipment components, particularly of printing machines, including at least one electric motor having a rotor designed for rigid and direct coupling to the component, further including by one or several angle encoders for registering the angular motion of the rotor of the electric motor and/or the component, a signal processing module which receives the actual angle position signals from the angle encoder or encoders and which also receives the setpoint data for comparison with the actual data, and a power amplifier controlled by the signal processor and used for driving the electric motor.
