Spindle with electromotor drive for a spinning machine

A spindle drive apparatus for a spinning machine of the type having a bobbin supporting spindle rotatably mounted in a bearing housing in the spindle bank of the spinning machine and on which spindle a rotor is fixedly mounted for rotation therewith, said apparatus comprising:

• a stator, mounted on the spindle bank and surrounding the rotor, for rotating the rotor and the spindle, said stator including a plurality of electrically conductive coils and a stack of magnetically active plates shaped for receiving said plurality of coils;
• an interconnecting member, connected to the spindle bank on one axial end of said stator, for mounting said stator on the spindle bank,
• said coils having a first portion projecting from said stack of plates in a direction toward said interconnecting member and a second portion projecting from said stack of plates in a direction away from said interconnecting member;
• a protective cover encasing said first and second projecting portions of said coils, said protective cover including a first protective cover portion extending from said stack of plates in said direction towards said interconnecting member for substantially encasing said first projecting portion of said coils and a second protective cover portion extending from said stack of plates in said direction away from said interconnecting member for substantially encasing said second projecting portion of said coils;
• and
• means for securing said second protective cover portion to said interconnecting member including a plurality of brackets, one end of each bracket being fixedly connected to said interconnecting member and the other end of each bracket being fixedly connected to said second protective cover portion.
