Detailed Application Insights

AKT’s BLDC motors are at the heart of modern industrial and commercial technology. Their unique advantages make them the ideal choice for specific, high-performance tasks.

Industrial Automation & Robotics: Our motors are used in conveyor systems, automated sorting, and assembly lines where 24/7 operation is required. For robotics, the high torque-to-weight ratio of our NEMA-equivalent motors allows for powerful robotic arms and AGV drive wheels.
Medical and Laboratory: The medical field demands precision and low noise. Our smaller-frame motors are perfect for blood pumps, dental tools, and laboratory centrifuges. Because they are brushless, there is no carbon dust, making them suitable for cleanroom environments.
Electric Vehicles & Pumps: High efficiency is critical for battery-powered applications. Our larger motors are used as high-efficiency drive wheel motors for electric utility carts, AGVs, and other traction systems.

How to Select Your Brushless DC Motor

Choosing the right unit is crucial for your application’s success. Consider these key factors when browsing our series:

Frame Size & Torque: This is the most important factor. A larger frame size (e.g., 110mm or 130mm) can deliver significantly more torque than a smaller one (e.g., 42mm). Match the motor’s continuous torque rating to your application’s load.
Operating Voltage: We offer a wide range from low voltage (12V, 24V, 48V) to high voltage (170V, 310V). Low-voltage motors are perfect for battery-powered devices (like AGVs), while high-voltage motors are ideal for industrial machinery running on AC power.
Speed (RPM): Match the motor’s rated speed to your needs. Our line ranges from 3000 rpm on larger units to over 8,000 rpm on smaller, high-speed models.
Feedback & Customization: Do you need precision positioning? Add an encoder to turn your unit into a full servo system. We also offer integrated gearboxes, custom shafts, and more. Contact us to discuss your specific requirements.

BLDC Motor vs. Brushed DC (PMDC) Motor

While both motor types serve vital roles, the choice depends on prioritizing cost, complexity, or lifespan. We offer both technologies to fit your exact application needs.

Commutation & Longevity: Brushed DC (PMDC) motors use a robust mechanical commutator for straightforward operation. Brushless DC (BLDC) motors rely on electronics, resulting in a cleaner operation and a lifespan often exceeding 20,000 hours.
Efficiency & Cost: PMDC motors offer the lowest initial cost and simplest integration (requiring only voltage input). BLDC motors, while requiring an external driver, offer significantly higher power efficiency, which is critical for continuous-duty or battery-powered systems.
Speed & Torque: PMDC motors offer excellent performance and high torque at low speeds using a simpler setup. BLDC technology provides superior performance and lower noise at high RPM.
Primary Use: PMDC motors are valued where simplicity and lowest initial cost are the highest priorities. BLDC motors are valued for high-speed, precise control, and long, maintenance-free operation.
