Abstract
A spindle apparatus for winding fibers has a spindle which is directly fixed to a rotor of an electric motor. One of a pair of magnetically-coupled thrusting members is fixed to a rotary part of the apparatus, while the other of the thrusting members is fixed to a stationary part of the apparatus, so that a downward thrusting force is applied to the spindle to prevent lift of the spindle during rotation thereof.
