RESEARCH ON COMBINED COMPENSATED DRIVING LINEAR SERVO UNIT

Abstract

Abstract: A large power combined compensated driving linear servo unit based on the principle of voice coil motor is presented. Its force constant, maximum driving force and maximum driving current are 82 N/A, 820 N and 10A respectively. The basic principle and dynamic differential equation of the servo unit are given and its combined compensated driving magnetic circuit and magnetic circuit equations are introduced. Gives a example of this kind of linear servo unit and its features. At present, the linear servo system based on this servo device has been used in CNC lathe for pistons.

Key words: Combined compensated driving, Linear servo, Magnetic design, Piston
