Screw guide module brand equipment _ _ linear module manipulator high-speed linear module principle
the precision linear motor by simple transmission mechanism to reduce the interpolation problem of hysteresis, positioning accuracy and repeat precision, the absolute accuracy, through position detection feedback control will be more & other; Rotating servo motor ball screw & throughout; High, and easy to implement. Linear motor position precision can reach 0. 1μ m。 “ Rotating servo motor ball screw & throughout; To a maximum of 2 ~ 5 & mu; M, and the Claim of CNC - Servo motor - Apparatus - there is no gap Thrust bearing - The cooling system - High precision rolling guide - Nut - Workbench closed-loop transmission part of the whole system to lightweight, grating precision is higher. To achieve high stability, & other; Rotating servo planetary gear motor ball screw & throughout; Taking biaxial drive, linear motor is high fever parts, take strong cold measurement, to achieve the same purpose, linear motor is to pay more cost.
speed linear motor has a considerable advantage, linear motor speed reached 300 m/min, the acceleration achieve 10 g; Ball screw speed of 120 m/min, the acceleration of 1. 5克。 From the contrast of speed and acceleration, the linear motor has a considerable advantage, and linear motor after successfully solve the problem of heating speed further improved, and & other; Rotating servo motor ball screw & throughout; In speed is restricted to improve more.
life because of the moving parts in terms of the linear motor and fixed components are installed between the gap, no contact, not because of the dynamic high-speed reciprocating motion of wear and tear, long use between changes in movement and positioning accuracy, suitable for the occasion of high precision. Ball screw cannot ensure accuracy in the high speed reciprocating motion, because of the high speed friction, the wear and tear of lead screw nut, affecting the precision of the motion requirements. Can't meet the demand for high precision occasions.
