Abstract

This invention relates to coil drives for spinning machines and similar machines. The aim of the invention is to simplify the design of the spinning mask by combining the performance of the spindle winding functions and the layout of the thread. The electrotwist is a case with a composite stator pressed into it. A cylindrical rotor is installed concentrically with it, into which a spindle is set in a cone fit. One half of the composite stator is made in the form of a stator of an arc-voltage motor, the other - in the form of an inductor of a linear motor. The contactless suspension of the rotor of the electrocauterine is carried out by the interaction of the lifting forces of the gas lubricant layer supplied to the working gap between the stator and the rotor and the electromagnetic forces of attraction of the rotor to the stator. At the same time, both rotational and reciprocating movement of the electro-spindle shpindles will make it possible to combine the winding process in the electro-spindle with the process of laying out the thread. 2 Il.

The rotational movement of the pinch 8 provides winding of the thread, and the reciprocating movement of the pinch 8 provides the layout of the thread on the cartridge (not shown) with the formation of a package of the required shape. During the electro-spinning operation, the radial and angular loads perceived the cut of the spindle; in fig. 2 - the same, they are crossed with a layer of gas lubricant in the stators, the cross section. Stability of the non-contact suspension of the electro-spindle of the spindle 3, is provided by the interaction of the lifting body 1, mounted on the external depreciation device 2, stators 3 and 4, installed in housing 1, containing 15
