Permanent magnet synchronous linear motor device for floating gate

Abstract

The invention discloses a permanent magnet synchronous linear motor device for a floating gate, which is composed of a stator component, a mover component, a position detecting device, a microcomputerdriver and a controller. The mover component is in a feedback connection with the microcomputer through three Hall sensors, a transparent belt and a penetrating encoder or a magnetic grid at a position corresponding to the stator component; the gap between the mover component and the stator component is separated by a roller component; and the roller component slides through the cooperation of aU-shaped roller and a track on a stator profile. The invention selects a permanent magnet synchronous linear motor as a driving device; since the stator component does not contact directly with the mover component and a iron core in the stator component has a vertical magnetic force to a permanent magnet in the mover component, the device has the advantages such as simple structure, safety and stability, low wear rate, long service life, energy conservation and environmental protection, low noise and easy pushing in power failure.

Description

technical field [0001] The invention relates to a linear motor, in particular to a permanent magnet synchronous linear motor device for a suspension door. Background technique [0002] Suspension door is a mechatronics device with long-term, frequent and reciprocating work. It not only requires high reliability and safety, but also requires it to have the characteristics of stable operation and low noise. The existing translation Automatic doors generally use a rotating motor as the power source. Through mechanical transmission (ball screw or toothed belt) transmission, the rotary motion is converted into linear motion to realize the opening and closing of the door. This type of rotating motor is converted by mechanical transmission. The device has low transmission efficiency and high motion noise. After a long time of operation, the motion components will wear out, affecting motion accuracy and stability, and the installation and maintenance costs are high. Contents of th...

[0002] Suspension door is a mechatronics device with long-term, frequent and reciprocating work. It not only requires high reliability and safety, but also requires it to have the characteristics of stable operation and low noise. The existing translation Automatic doors generally use a rotating motor as the power source. Through mechanical transmission (ball screw or toothed belt) transmission, the rotary motion is converted into linear motion to realize the opening and closing of the door. This type of rotating motor is converted by mechanical transmission. device, the transmission efficiency is not high, and the movement noise is large. After a long time of work, the movement components will wear out, affecting the movement accuracy and stability, and the installation and maintenance costs are high.
