LINEAR MOTOR OF DELIVERY SYSTEM

摘要

A linear motor of a delivery system is provided to increase efficiency and accuracy of a controller with a small number of controllers by enabling a Hall sensor to input a phase signal of a part where a rotor is located. In a linear motor of a delivery system having a stator part(100) and a rotor part(110) attached with a permanent magnet(120), a plurality of Hall sensors(150) is located on the upper part of the stator part and outputs a high/low phase signal by detecting magnetic flux generated according to the polarity of a magnetic field. A PCB board is used for installing the Hall sensor at the stator part. A position sensor(140) receives the phase signal of the Hall sensor in the position of the rotor part and then transfers the phase signal to a controller. The controller drives a winding by receiving the phase signal of the position sensor. A selector inputs only one phase signal among the plurality of Hall sensors.
