Abstract
In an apparatus at a spinning preparation machine, especially at a carding machine, cleaner, draw frame, combing machine or the like, having at least one electric motor-driven roller, which is rotatably mounted about its longitudinal axis, the roller is caused to rotate by means of forces of an electromagnetic field that act on at least one roller end-face. In order to achieve a substantially increased drive output and braking output and a high torque in a simple manner, an electromotive drive means is present having a rotor and a stator which are integrated into the roller and into an immobile machine element associated with the roller.
Claims18
An apparatus at a spinning preparation machine, comprising:
- at least one electrically-driven roller and at least one immobile machine element adapted to associate with the at least one roller, wherein one of the at least one roller and the at least one immobile machine element comprises a rotor of a electric drive motor and the other of the at least one roller and the at least one immobile machine element comprises a stator of the electric drive motor, wherein the rotor is adapted to mount at least one permanent magnet and the stator is adapted to mount electromagnetic coils, and wherein an alternating current is applied to the electromagnetic coils to drive the at least one roller by a resulting rotary field.
An apparatus at a spinning preparation machine having at least one electrically-driven roller, at least one stationary side panel associated with the at least one roller, and an electric drive motor for driving the at least one roller, wherein the electric drive motor comprises a rotor joined directly to the at least one roller and a stator joined directly to the at least one stationary side panel, and wherein when an alternating current is applied to the stator the at least one roller is driven by a resulting rotary field.
A method of driving a roller of a spinning preparation machine comprising:
- constructing a rotor integrated into one of said roller and an immobile machine element associated with said roller;
- constructing a stator integrated into the other of said roller and said immobile machine element;
- and supplying an alternating electrical current to said rotor and/or stator for driving the roller by a resulting rotary field.
