The ball screw stepper converts rotary motion to linear motion within the motor, allowing the cantilever mechanism to be directly connected to the motor, making the mechanism as compact as possible. At the same time, there is no need for an intermediate transmission link to enable higher precision, higher efficiency and longer life.
KGG Stepping Motor And Ball / Leading Screw External Combination Linear Actuator
Biochemical analyser is a medical institution for clinical diagnosis and life sciences, biochemical research and other research institutions to carry out scientific research one of the necessary instruments, mainly for the determination of human body fluids in a variety of routine biochemical indicators. Fully automatic biochemical analyser has the functions of precise sample filling and automatic loading, with high precision, good repeatability, full-featured, multi-test items, etc., and its rapid, simple, micro-volume and other characteristics are particularly prominent. In terms of pharmaceutical filling, different from the traditional stepping motor drive mode,ball screw stepper motor is more and more widely used in automatic biochemistry analyser.
KGG currently offers the following products: 20mm, 28mm, 35mm, 42mm, 57mm and 86mm two-phase hybrid linear stepper motors.
●Repeatable positioning accuracy up to 0.01mm
Ball screw stepping motors are easier to realise than rotary servo motors and ball screws due to the simplicity of the drive mechanism and the reduction of interpolation hysteresis, which results in higher positioning accuracy, repeatability, and absolute accuracy.
●High speed up to 300m/min.
From the speed and acceleration comparison, linear screw stepping motor has considerable advantages, linear screw stepping motor speed up to 300m/min, acceleration of 10g; ball screw speed of 120m/min, acceleration of 1.5g. And linear screw stepping motor in the success of the solution to the problem of heating speed will be further improved, and "rotary servo motor & ball screw The speed of "Rotary Servomotor & Ball Screw" is limited, and it is difficult to increase the speed much more.
●High life span and easy maintenance
Ball screw stepping motors are suitable for high-precision applications because there is no contact between the moving parts and the fixed parts due to the mounting gap, and there is no wear and tear due to the high-speed reciprocating motion of the actuator, and there is no change in the positioning accuracy of the motion when used for a long period of time.
