MEASUREMENT OF ELECTROSPINDLE ROTOR DISPLACEMENT

摘要

In the paper an induction converter for measuring the linear displacement of the individual motor-driven spindle rotor of a ring spinning frame. The motor-driven spindle rotor is drawn into the asynchronous motor stator on connecting the asynchronous motor to the supply voltage source. The rotor displacement is caused by the force acting along its rotation axis formed by the electrodynamic action of the electromagnetic field.
