Application of integrated stepping motor in automatic biochemical analyzer
With the continuous advancement of medical technology, automatic biochemical analyzers play an increasingly important role in clinical diagnosis. As a key part of automatic biochemical analyzers, integrated stepper motors play an indispensable role in the operation of instruments with their high efficiency, precision and stability.
01.Equipment Introduction
An automatic biochemical analyzer (Biochemical analyzer, Clinical-chemistry analyzer), also referred to as an automatic biochemical analyzer, is a computer-controlled analytical instrument that automatically combines the steps of sampling, adding reagents, mixing, heat preservation reaction, detection, result calculation, reliability judgment, display and printing, and cleaning in biochemical analysis.
It can be applied to the fields of medicine, water quality, food and clinical analysis. In clinical analysis, biochemical analyzers are mainly used to analyze various biochemical indicators in human blood and other body fluids, such as hemoglobin, cholesterol, glucose, amylase, urea nitrogen, albumin, total protein, inorganic phosphorus, uric acid, calcium, etc.

Traditional Solution
Traditional electronic control systems generally use control solutions such as PC+MCU+touch screen+driver+stepper motor. This not only has cumbersome wiring and occupies a large space, but the entire control process is also very complicated, which greatly increases the development cycle.
Upgrade plan
In an automated biochemical analyzer，The integrated stepper motor is mainly used to drive key components such as reagent needles, sample needles and stirring devices.
By controlling the rotation angle and speed of the motor, the reagent needle can be moved accurately to ensure accurate addition of the reagent; The precise movement of the sample needle can achieve accurate sample aspiration and precise sample addition; The precise control of the stirring device can ensure the full mixing of the reagent and the sample, providing good conditions for subsequent biochemical reactions.
In addition, the integrated stepper motor can also be used to control the instrument's robotic arm, conveyor and other components to achieve automatic transmission and detection of samples.
Through the precise control of the motor, it can ensure that the sample is transferred quickly and accurately between the various detection units, thus improving the detection efficiency and accuracy of the instrument.
【Advantages of integrated stepper motor】
High integration improves the portability of equipment: The integrated stepper motor integrates functional modules such as stepper motor, servo drive, encoder and controller, which greatly reduces the size and weight of the equipment. At the same time, it simplifies system wiring and reduces potential failure points.
Flexibility to meet diverse needs: The integrated stepper motor supports CANopen/Modbus communication and can be flexibly controlled and adjusted as needed to adapt to different work requirements.
High-precision positioning improves measurement accuracy: The integrated stepper motor has high positioning accuracy and can achieve high-precision positioning of mobile devices.
Multiple control modes: support PP, VM, PV, PT, HM, IP, CSP, CSV, CST Standard mode; support NiMotion position mode, NiMotion speed mode, NiMotion torque mode.
High-speed response improves equipment efficiency: The integrated step servo motor has a fast response speed and can quickly adjust the angle and position of the equipment. This means that the robot can obtain environmental information more quickly, improving the working efficiency and responsiveness of the equipment.
Complete alarm function: The integrated stepper motor power-on self-diagnosis can detect hardware failures in time to avoid affecting system operation. It is equipped with multiple safety protection functions, and the LED flashing alarm can intuitively display the current status of the motor. It also has protection functions such as overvoltage/undervoltage, overheating, overcurrent, and stall alarm.
