Abstract: A component tape transport wheel, a component tape transport system and a method of operating a component tape transport system are provided, in which there is a rigid coupling between a transport wheel and an encoder wheel which is arranged on the transport wheel and whose position relative to a sensor can be determined. By this rigid coupling between the transport wheel which moves the component tape and a registration system including an encoder wheel and sensor for registering the position of the transport wheel, it is possible to register the position of the transport wheel at any time with the greatest accuracy. Even after a component tape transport system has been switched off, a determination of the absolute position of the transport wheel is possible, since the distance between two encoder elements of the encoder wheel is less than any play possibly caused by a drive of at least one of the transport wheel and an associated gear mechanism.

Abstract: A tensioning device used in pulling off cover films, and a component feed module including the tensioning device, includes a force sensor for measuring a pull-off force applied to the cover film. The force sensor is coupled to a control device, by which the film drive can be controlled to control the pull-off force of the cover film in such a way that the pull-off force is kept substantially constant.

Abstract: An angular transmitter integrated with a small electrical motor and supplying phase-shifted signals has at least one magnetic part having an end face and alternatingly arranged poles on the end face. At least one sensor is arranged opposed to the at least one magnetic part. The at least one sensor has at least two sensor elements arranged angularly relative to one another. The at least two sensor elements are rotated relative to one another by 90° or by 60°. The at least two sensor elements cross one another.

Abstract: An electric motor, having a coil without iron-core and having an integrated electronic control device, has a sine commutator supplying the electric motor with sine-shaped currents or voltages. The control device has an rpm control with which a magnitude of the sine-shaped currents or voltages is preset. The electronic control device also has a position control for the motor shaft.

Abstract: A microelectric motor has a housing and a rotatable motor shaft extending axially in the housing. The housing has an axial length. A rotor is fastened to the motor shaft and a stator is positioned in the housing for cooperating with the rotor. A receiving chamber is provided in the housing within its axial length. The transducer is positioned in the receiving chamber.
