Linear screw stepper motors reduce the problem of interpolation lag
It is difficult to improve more. So, what are the advantages of linear screw
stepper motors on high-speed machine tools compared to servo motor ball screws?
To In terms of accuracy: Linear screw stepper motors reduce the problem of
interpolation lag due to the simple transmission mechanism. The comparison of
linear screw stepping motor and traditional 'rotating servo motor ball screw'
has attracted the attention of the industry.5g. Motor. Now some technologically
advanced machining center manufacturers have begun to apply linear screw
stepping on their high-speed machine tools. If you want to achieve higher
stability, the 'rotating servo motor ball screw' needs to be driven by two axes.
In order to adapt to the Blower Motor
Suppliers development of the industry, drive technology must also develop
rapidly.1μm. Ball screws cannot guarantee accuracy in high-speed reciprocating
motion. Long-term use does not change the positioning accuracy of the motion,
which is suitable for high-precision occasions. High-speed friction will cause
the wear of the screw nut, which affects the accuracy requirements of the
motion, and cannot meet the high-precision requirements.
The linear screw
stepper motor has a speed of 300m/min and an acceleration of 10g; the ball screw
has a speed of 120m/min and an acceleration of 1. Positioning accuracy,
reproducibility, precision, and position detection feedback control will be
higher than 'rotating servo motor ball screw' and easy to implement. The linear
screw stepper motor is a high-heating component and requires strong cooling
measures. In terms of speed: The linear screw stepper motor has considerable
advantages..Industrial equipment changes with each passing day.
From the
comparison of speed and acceleration , The linear screw stepper motor has
considerable advantages, and the speed of the linear screw stepper motor will be
further improved after successfully solving the heating problem, while the
'rotating servo motor ball screw' is limited in speed. To achieve the same
purpose, the linear screw step Entering the motor will have to pay a greater
price.
Linear screw stepper motor positioning accuracy can reach 0. Rotary Servo Motor Ball Screw; up to 2~5μm, and requires
CNC-servo motor-gapless coupling-thrust bearing-cooling system-high Precision
rolling guide-nut seat-table closed loop The transmission part of the entire
system should be lightweight, and the grating precision should be high. In terms
of life: Linear screw stepper motor has installation clearance between moving
parts and fixed parts, no contact, and will not be worn by the high-speed
reciprocating movement of the mover
