High Performance Cost-Effective Electric Actuator Core Linear Motor
Description
Linear motors' principle is based on Lorentz force, in which the combination of electric and magnetic force on a point charge due to electromagnetic fields. (If a particle of charge q moves with velocity v in the presence of an electric field E and a magnetic field B, then it will experience a force) F=q[E+(v*B)] In addition, the use of magnet arrangement and multiple forcers can achieve multiple forcers' independence movement on single-axis stators and without stroke restriction. Also nanopositioning control. can be easily realistic via matching the high resolution feedback system.
coreless U shape motor is with no backlash, zero cogging force and low velocity ripple. Besides, there is no attraction force between forcer and stator because of coreless design. LONG-A2000 Series Linear motor was designed for low payload application and continues motion curve, including high speed and low payload of automatic machine, high clean environment of manufacturing equipment for semi-conductors and LCDs, automated optical inspection (AOI), EDM machine tool and CNC piston turner.
