Linear motor in high-speed gantry machining applications, linear motor has a simple structure, non-contact operation, low noise, high speed and accuracy, easy to control, easy maintenance, high reliability. With the development of advanced manufacturing technologies such as ultra-high-speed cutting and ultra-precision machining, higher and higher requirements are put on the performance of the machine tools.

        With the rapid development of motor technology, in recent years, the linear motor and its drive control system are maturing technically, and have the advantages that traditional transmission devices can not match.

       In the CNC machine tools, the use of linear motors instead of the traditional high-speed ball screw, and the original rotary motor drive the biggest difference is: Remove the motor to the table between the mechanical intermediate transmission links. Direct drive to avoid the screw drive in the backlash, inertia, friction and lack of rigidity and other shortcomings, bringing the original rotary motor drive performance can not reach the performance indicators and advantages.

        In the high-speed gantry five-axis machining center, a total of two feed axis linear motor drive, which uses four linear motor x-axis, y-axis using two linear motors.

        The y-axis, for example, briefly introduces the choice of linear motor, y-axis main load for the ram, the estimated quality of about 6200kg, the maximum acceleration required to reach five meters per second, peak thrust requirements of 7000, cattle friction and resistance 200 cattle, through calculation can get its maximum acceleration of 15,600 cattle, so the two can choose to drive two linear motors together.
