Driven by rising e-commerce penetration and competition in supply chain efficiency, “Smart Logistics” has become the industry standard. The core of modern logistics and warehousing systems is efficiency and accuracy; the throughput of equipment (like sorters, AGVs) directly dictates the center’s capacity. This places extreme demands on drive systems: 1) High Dynamic Response: AGV drive wheels and sorter diverter arms require extremely high acceleration/deceleration and fast response. 2) High Reliability & Long Life: Equipment must run 24/7, demanding tens of thousands of hours of life and high stability from motors and gearboxes. 3) Precise Control: AGV navigation, fork positioning, and sorting accuracy all depend on precise speed and position control. 4) High Efficiency & Integration: Reducing the total energy consumption of large warehouses and simplifying complex wiring for distributed deployment.
AKT Product Solution
AKT provides drive technologies for intelligent logistics, focusing on Brushless DC Motors (BLDC) and (Closed-Loop) Hybrid Stepper Motors.
- High-Efficiency & High-Torque Drive Solution (AGV/AMR):
The drive wheels of AGVs/AMRs require high efficiency (for battery life), high torque (for start-stop and climbing), and precise speed control. Our high-torque BLDC motors (e.g., 86mm, 110mm series) paired with high-torque, high-strength planetary gearboxes form a drive-wheel assembly with extremely high torque density. Paired with our low-voltage BLDC drivers (supporting 24V/48VDC, with CANopen or EtherCAT), they integrate seamlessly with the AGV’s central controller for high-precision differential steering and motion planning. - High Dynamic Response Solution (Sorting Systems):
In cross-belt or wheel sorters, hundreds or thousands of diverting units need to respond instantly. Our low-inertia BLDC motors (e.g., 42mm, 57mm) or Closed-Loop Stepper Motor Systems are the ideal choice. They can start, stop, and reverse direction in milliseconds, ensuring parcels are accurately diverted. In such high-frequency start-stop applications, the closed-loop stepper solution ensures zero step loss and extremely high reliability. - High-Reliability Transmission Solution (Conveyors):
For conveyor rollers, our BLDC motors (which can integrate planetary gearboxes) are the ideal drive, offering a lifespan far superior to traditional PMDC motors. For vertical motion equipment like stacker cranes, our BLDC servo motors combined with planetary gearboxes and an integrated electromagnetic brake accessory provide a safe, reliable, and compact drive unit, ensuring goods do not slip during a power outage.
Engineering & Customization Capabilities:
We provide highly integrated modules for the logistics industry: including “smart wheels” that integrate the BLDC motor, planetary gearbox, encoder, and driver into one unit; customizing motors with electromagnetic brakes; and providing drivers that support major industrial buses for distributed control, drastically simplifying field wiring and commissioning.
Typical Application Equipment Examples
- AGV/AMR Drive Wheel Assembly:
This is the core of logistics automation. Our BLDC motor + high-torque planetary gearbox integrated assembly is designed to withstand high radial loads (i.e., the AGV’s total weight), is compact, and can be directly integrated into the wheel. Its high efficiency and low-voltage (48V) nature are a perfect match for battery systems, while the CAN bus driver makes it an “intelligent leg” that is easy to dispatch. - Cross-belt / Wheel Sorter:
Each cart on a cross-belt sorter, or each wheel on a wheel sorter, requires an independent drive unit. Our small BLDC motors (or closed-loop steppers), thanks to their small size, high response, and reliability, allow for high-density distributed deployment. Via bus drivers, the main control system can manage thousands of motors in real-time, achieving astonishing sorting efficiencies of tens of thousands of items per hour. - Automated Storage/Retrieval System (AS/RS) Stacker Crane:
The Z-axis (lift) of a stacker crane is critical. Our high-power BLDC servo motor with a planetary gearbox and brake provides smooth, high-speed vertical lift and ensures absolute safety. The X-Y extension of its forks is often driven by our high-precision stepper motors for accurate pallet retrieval.
