Principle of Automatic Sampling Systems

The core function of an automatic sampling system is to achieve full-process automation of “automatic identification – precise sampling – sample transfer – reset standby.”

It can complete the sampling operation of designated media (liquids, gases, solid particles, etc.) without manual intervention, ensuring the standardization and consistency of the sampling process while avoiding errors and contamination caused by manual sampling.

Its core working principle can be summarized in three steps:

First, the system uses sensors (such as liquid level sensors, pressure sensors, and position sensors) to identify the sampling point and medium status, then transmits signals to the controller.

Second, after receiving instructions, the controller drives the actuators (sampling arms, sampling pumps, valves, etc.) to move accurately to the sampling position and complete quantitative or qualitative sampling.

Finally, after sampling is completed, the actuators return to their original positions, the samples are transferred to the detection module, and the system enters the next sampling cycle.

Throughout the process, the motion accuracy and power stability of the actuators directly determine the accuracy of sampling data and the operating efficiency of the system, while the drive motor serves as the core power source of the actuators.

How Motors Drive Automatic Sampling Systems

The motor plays the role of the “core power output unit” in automatic sampling systems. Through coordination with the controller and actuators, it realizes power driving throughout the entire sampling process. The specific drive logic can be divided into three levels to meet the motion requirements of different actuators:

Power transmission

The motor output shaft connects to actuators such as sampling arms, sampling pumps, and valves through transmission components such as couplings and gears, converting the motor’s speed and torque into driving force for the actuators, such as driving the lifting and rotation of the sampling arm, enabling constant-speed pumping by the sampling pump, and achieving precise valve opening and closing.

Precise control

The motor works together with the controller and encoder to achieve precise adjustment of speed, position, and torque. For example, during sampling, the pump speed must be controlled to ensure quantitative sampling, and the positioning of the sampling arm must reach millimeter-level accuracy to avoid sampling deviation. All of these rely on the motor’s precise response and control capability.

Operating condition adaptability

In response to sudden conditions during sampling, such as changes in medium resistance or pipeline blockage, the motor must have a certain overload capability to ensure that actuators do not jam or stop, thereby guaranteeing continuous sampling operation.

Through its integrated “brushless drive + planetary reduction” design, the TSL-16GP-C1636002 brushless coreless planetary gear motor can directly adapt to various actuators in automatic sampling systems, achieving dual optimization of power and control.

Requirements of Automatic Sampling Systems for Motors

Automatic sampling systems operate in diverse scenarios (laboratories, field environments, industrial sites, etc.) and require high sampling precision and stability. Therefore, the requirements for drive motors are highly targeted and mainly focus on the following five aspects:

Compact Size

Most automatic sampling devices, especially portable and integrated equipment, have limited internal space. Therefore, motors must feature compact size and high power density. Miniature motors with diameters around 16mm are mainstream choices and can be flexibly installed inside equipment.

Strong Overload Capability

Routine sampling operations (such as pump driving and valve switching) require stable rated torque, while sudden conditions (such as pipeline blockage or viscous media) demand strong stall torque. Ideally, the rated torque should meet normal load requirements, while the stall torque should reach more than eight times the rated torque to prevent motor burnout and sampling interruption.

Fast Response

Actions such as sampling arm positioning and quantitative sampling require motors with no cogging effect, smooth operation, micron-level positioning accuracy, and fast start-stop response without lag, thereby avoiding sampling deviation and cross-contamination.

Low Noise and Low Vibration

In laboratories and precision testing scenarios, equipment noise and vibration requirements are strict. Motors must maintain low noise and low vibration during operation to avoid affecting testing accuracy or causing sample shaking.

Long Service Life and Maintenance-Free Operation

Some sampling systems need to operate continuously 24/7 (such as online monitoring equipment) or are installed in unattended outdoor environments. Therefore, motors must have no easily worn components and provide long service life, reducing maintenance frequency and lowering operation and maintenance costs.

Why Brushless Coreless Gear Motors Are Needed

Currently, the commonly used drive motors in the industry mainly include traditional brushed DC motors, ordinary stepper motors, and brushless coreless gear motors. By comparing the core performance of these three types, it becomes clear that brushless coreless gear motors are better suited to the core requirements of automatic sampling systems.

Compared with Traditional Brushed DC Motors

Traditional brushed motors are bulky, their carbon brushes wear easily, and they require frequent maintenance. In addition, they have low efficiency and high power consumption, making them unsuitable for portable devices and unattended applications.

Brushless coreless motors adopt a coreless structure. Combined with a 16mm miniature size and planetary gearbox, they can achieve high torque output, eliminate carbon brush wear, provide maintenance-free operation, and reduce power consumption, thereby completely solving these core pain points.

Compared with Ordinary Stepper Motors

Ordinary stepper motors have obvious cogging effects, large vibration and noise during low-speed operation, insufficient positioning accuracy, low torque density, and weak overload capability, making them prone to jamming and shutdown.

Brushless coreless gear motors have no cogging effect, provide low-noise and smooth operation, achieve micron-level positioning accuracy, offer high torque density and strong overload capability, and ensure continuous and precise sampling processes.

In summary, brushless coreless gear motors effectively compensate for the shortcomings of traditional motors and perfectly match the core requirements of automatic sampling systems, making them the preferred drive component.

Strong Anti-Interference Capability

The brushless drive design provides excellent electromagnetic interference resistance, enabling stable operation in complex electromagnetic environments such as industrial sites and laboratories, thereby ensuring the continuity and reliability of sampling systems.

Equipped with Encoder

The motor is equipped with an encoder that can provide real-time feedback on motor position and speed. Combined with the controller, it enables closed-loop control, further improving positioning accuracy and repeatability of sampling actions, ensuring precise sampling point positioning and meeting the requirements of higher-end precision sampling applications.
