Industrial automation is the cornerstone of modern manufacturing, undergoing a profound transformation from standalone automated units to fully intelligent and flexible production lines. Modern lines demand rapid changeovers between product batches (Flexible Manufacturing), placing unprecedented demands on the dynamic performance and positioning accuracy of actuators. For instance, in high-speed conveying and sorting systems, actuators must complete precise positioning and diversion in milliseconds. In “flying shear” applications, the motion control system must dynamically synchronize with the main line. In processes like labeling or filling, the synchronicity and repeatability of motion directly determine the yield rate. Furthermore, the trend towards miniaturization and integration requires motion units to offer high power density in a compact volume while reducing energy consumption and maintenance costs. Therefore, high response, high precision, high reliability, and high power density have become the core metrics for evaluating motion control solutions.
AKT Product Solution:
To address the diverse and stringent demands of industrial automation, AKT provides system-level solutions centered on Brushless DC Motors (BLDC) and Hybrid Stepper Motors.
- High-Precision Positioning & Torque Control Solution: In applications demanding precise positioning and high torque at low-to-medium speeds (e.g., precision dispensing, vision alignment, material gripping), our Hybrid Stepper Motor series (frame sizes from NEMA 8 to NEMA 36) demonstrates excellent performance and cost-effectiveness. We offer not only standard 1.8° step angles but also 0.9° high-resolution models, doubling the positioning accuracy. Paired with AKT’s high-performance stepper drivers (featuring advanced micro-stepping and vibration suppression algorithms), high-precision positioning can be achieved in an open-loop state, significantly reducing system cost and commissioning complexity.
- High Dynamic Response & Velocity Control Solution: For applications requiring high dynamic response, a wide speed range, and complex velocity control (e.g., high-speed sorting, AGV wheel drives, material conveying), our high-performance Brushless DC Motor (BLDC) series is the ideal choice. This series (with frame sizes from 28mm to 130mm) utilizes high-energy permanent magnets and optimized electromagnetic designs, featuring extremely low rotor inertia and high power density, capable of achieving rated speeds of several thousand RPM. Combined with AKT’s intelligent BLDC drivers, which utilize FOC (Field-Oriented Control) algorithms, they provide smooth, efficient torque output and precise closed-loop speed control across the entire velocity range.
- High-Reliability & High-Load Solution: To mitigate the risk of step loss in high-speed or variable-load conditions common in traditional stepper systems, we offer Closed-Loop Stepper Motor Systems (integrating high-resolution encoders). This system combines the high torque characteristics of a stepper with the closed-loop reliability of a servo. When applications demand extreme torque or low-speed output, our Precision Planetary Gearboxes (available with backlash ratings as low as ≤10 arc-minutes) can be standardized and integrated with the aforementioned BLDC or stepper motors. This Integrated Power Unit (IPU) not only enhances torque density but also greatly simplifies the customer’s mechanical design and assembly process.
Engineering & Customization Capabilities:
We understand that standard products cannot meet every application’s needs. AKT provides in-depth customization services, including but not limited to: custom motor shafts (length, D-cuts, keyways, threading), special flange mountings, winding optimization for specific voltages (e.g., 24VDC, 48VDC, 310VDC), and the integration of accessories such as electromagnetic brakes and high-resolution encoders (incremental/absolute).
Typical Application Equipment Examples
- Automated Guided Vehicles (AGV/AMR): The wheel drive and steering systems of AGVs require high torque output, precise speed control, and high energy efficiency within a compact space. Our high-power BLDC motors (e.g., 86mm, 110mm series) combined with high-torque planetary gearboxes form a drive-wheel assembly with extremely high torque density. Paired with our BLDC drivers supporting CANopen/EtherCAT buses, they integrate seamlessly with the AGV’s central controller for high-precision differential steering and path tracking.
- Semiconductor & Electronics Manufacturing (SMT/AOI): The feeders on SMT pick-and-place machines and the Z-axis of AOI inspection cameras demand extremely fast and precise micro-movements. Our small hybrid stepper motors (e.g., NEMA 8, 14, 17), with their high resolution, rapid response, and inherent holding torque, are the ideal choice for such applications, ensuring component feeding and inspection accuracy at high cycle rates.
- High-Speed Sorting & Conveying Systems: Cross-belt or swing-arm sorting systems require motors to perform high-speed start-stops and precise diversions in very short timeframes. Our low-inertia BLDC motors (e.g., 42mm, 57mm series) paired with high-performance BLDC drivers provide millisecond-level dynamic response, ensuring parcels are accurately sorted to their destinations on high-speed conveyors.
