Array of electromagnetic motors for moving a tool-carrying sleeve

Abstract

An array (10) contains a rotary electromagnetic motor (11) and/or a linear electromagnetic motor (12) that is (are) attached to a tool-carrying sleeve (19) of a machine tool that carries out high-speed working in order to draw off shavings, in which magnets (13, 14i) of the motor(s) are integral with the tool-carrying sleeve (19) itself. In the array (10) magnets (13, 14i) are made integral with the tool-carrying sleeve (19) by a hollow tube (15) that is attached coaxially to the tube on an inside wall (15g) where the magnets are attached coaxially. The array (10) also contains a hollow shaft (16) that is fixed in place while the array (10) is in operation and is inserted coaxially into the hollow tube (15). A number of stator induction coils (17) that interact with the magnets (13, 14i) are arranged on an outer surface of the hollow shaft, and coaxially with respect to the hollow tube.
