Linear motor driven feed has been widely used in nc machine tools, precision machining and other industries, the main a bit has the following several aspects: 1, wide range of feed speed. Can be from 1 m/s to more than 20 m/min, the processing center of fast-forward speed reached 208 m/min, and the traditional machine tool fast-forward speed & lt; 60 m/min, generally for 20 ~ 30 m/min. 2, good speed performance. Speed deviation of 0. Less than 01%. 3, high acceleration. Linear motor can be up to 30 g, maximum acceleration the current feed acceleration of machining center has up to 3. 24 g, feed acceleration of laser processing machine has reached 5 g, and the traditional machine tool feed acceleration under 1 g, general is 0. 3g。 4, high positioning accuracy. Using grating closed-loop control, position precision can reach 0. 1 to 0. 01m。 The application of feedforward control system driven by linear motor can reduce the tracking error more than 200 times. Because of the moving parts of good dynamic characteristics, sensitive response, plus interpolation control refinement, nanoscale control can be realized. Travel is not restricted. Traditional screw drive screw manufacturing restrictions, usually 4 ~ 6 m, a longer stroke need to answer the filament, and no matter from the manufacturing process or in performance is not ideal. And driven by linear motor, stator can be infinite length, and simple manufacturing process, there have been large X more than 40 m high speed machining center. 5, simple structure, stable movement, low noise, the moving parts of friction small, wear small, long service life, safe and reliable. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
