Abstract:

As automation technology advances,Automated Guided Vehicles (AGVs) have become indispensable in various industries,serving as the cornerstone of intelligent logistics systems. The performance ofAGVs hinges significantly on their drive systems, with motors playing a pivotalrole in determining factors such as power, precision, stability, and longevity.This paper provides an in-depth exploration of the key considerations in AGVmotor selection, offering invaluable insights for engineers and practitioners.

I. Overview of AGV Motor Types

Brushed DC Motors: Foundational in design,brushed DC motors offer simplicity and ease of control, with rapid startup andbraking capabilities. However, concerns regarding spark generation and brushwear make them suitable for applications with lower lifespan requirements andsimpler control circuits.

Brushless DC Motors: By replacingtraditional brushes with electronic commutation, brushless DC motors mitigatespark and wear issues, enhancing efficiency and lifespan. Their electroniccontrol allows for smoother speed regulation and higher precision, making themideal for applications requiring speed and accuracy.

DC Servo Motors: Known for theirhigh-performance capabilities, DC servo motors achieve precise positioning androtation through pulse control. Offering superior control precision andresponse speed compared to brushless DC motors, they are often deployed inapplications demanding utmost accuracy and speed, such as high-precisionmaterial handling and assembly lines.

Stepper Motors: Stepper motors enableprecise control of angle displacement and rotational speed by modulating pulsequantity and frequency. While boasting simplicity and low cost, they exhibitrelatively lower control precision and response speed, rendering them suitablefor applications with less stringent accuracy requirements, such as simplematerial handling and path planning in AGVs.

II. Key Factors in AGV Motor Selection

Precision Requirements: The precisiondemanded by AGV operations directly influences motor selection. Forapplications necessitating high-precision positioning and rotation, prioritizingDC servo motors is prudent, while applications with less stringent precisionrequirements may consider brushless DC or stepper motors.

Speed and Dynamic Performance: AGV speedand dynamic performance exert a profound influence on motor selection. BrushlessDC and DC servo motors offer high rotational speeds and rapid responsecapabilities, making them suitable for scenarios requiring swift movement andfrequent changes in direction. Despite their lower rotational speeds, steppermotors provide smooth rotation characteristics, retaining applicability inspecific scenarios.

Load and Operating Environment: Motor loadcapacity and adaptability to operating environments are critical considerationsin the selection process. Tailoring motor capacity to AGV load requirements andconsidering features such as heat dissipation, waterproofing, and dustresistance are imperative for ensuring optimal performance and longevity.

Cost and Maintenance: Motor selectionencompasses cost and maintenance considerations. While brushed DC and steppermotors offer lower upfront costs, they incur higher maintenance expenses.Conversely, brushless DC and DC servo motors entail higher initial investmentsbut boast extended lifespans and lower maintenance costs, yielding overall costadvantages.

III. Integrated Development Trends in AGVDrive Control

As AGV applications diversify and evolve,motor enterprises are customizing motor design, manufacturing, and service tospecific application scenarios. Among these, integrated drive control design isrecognized as a future development direction. By integrating drivers,controllers, encoders, and motors into highly integrated and intelligentdevices, enhanced product performance, stability, reliability,cost-effectiveness, and maintenance simplicity are achieved.

IV. Conclusion

In summary, the selection of AGV motorsnecessitates a comprehensive assessment of precision requirements, speed anddynamic performance, load characteristics, operating environments, costconsiderations, and maintenance implications. As integrated drive controldesign continues to advance, future AGV motors are poised to become moreintelligent and integrated. Engineers and practitioners should judiciouslyselect motor types based on specific requirements and scenarios to realizeoptimal AGV performance and cost-effectiveness.
