Along with the development of the direct drive technology, straight screw stepper motor with the traditional 'rotary stepper motor ball screw driven by way of contrast to the attention of the industry. Now some technology of advanced machining center factory started on its high-speed machine tool applications. Precision: straight screw stepper motor for simple transmission mechanism to reduce the interpolation lag problem, positioning accuracy and repeat precision and absolute accuracy, by detecting position feedback control will be more 'rotary stepper motor ball screw' is high, and easy to implement. Straight screw stepper motor positioning accuracy can reach 0. 1μm. 'Rotary stepper motor ball screw' to a maximum of 2 ~ 5 microns, and require CNC -Stepper motor -Apparatus - there is no gapThrust 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, 'rotary stepper motor ball screw' to biaxial drive, straight screw stepper motor is high fever parts, take strong measures to cold to achieve the same purpose, straight screw stepper motor is more costly. Speed: straight screw stepper motor has a considerable advantage, straight screw stepper 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 speed and acceleration, on the contrast of straight screw stepper motor has a considerable advantage, and straight screw stepper motor speed after successfully solve the problem of heat will increase further, the 'rotary stepper motor ball screw' in speed is restricted to improve more. Life aspects: straight screw stepper motor because of the moving parts and fixed with installation clearance between parts, 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.
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. Telephone:
