1. High-Precision Robotic Arms
BLDC geared motors, with their spark-free commutation and low torque ripple, meet the micron-level motion accuracy demands of robotic arms. The planetary gear mechanism (e.g., our planetary geared motors) delivers high torque density and transmission efficiency, ideal for rotary drives in 6-axis articulated robots. For instance, an outer-rotor BLDC motor with a 1:80 gear ratio (as shown in our spec tables) achieves 0.1875° joint resolution, for automotive welding or precision assembly. Integrated motor-gearbox designs minimize backlash, further enhancing repeatability.
2. Collaborative Robots (Cobots)
For cobots requiring compact size and safe interaction, our 24V low-voltage BLDC geared motors offer:
Lightweight construction: Nanopolymer gears reduce drive unit weight to 300g, enabling installation in confined spaces.
Dynamic torque control: Hall sensors enable real-time load feedback, ensuring millisecond-level power cutoff during collisions for safe human-robot collaboration.
Low noise operation: Enclosed stator slots and precision gear meshing reduce noise below 55dB, compliant with ISO/TS 15066 standards.
3. Logistics Robots (AGV/AMR)
For mobile robots, our planetary + worm two-stage reduction solution provides:
Extended runtime: BLDC motors achieve >90% efficiency (30% more energy-saving than brushed motors) and prolong lithium battery life via electronic commutation.
Terrain adaptability: Custom gear ratios (e.g., 1:120) enable 0.06–5 Nm continuously adjustable torque for slopes and payload fluctuations.
IP67-rated protection: Fully sealed gearboxes withstand dust and humidity, with MTBF exceeding 20,000 hours in warehouse environments.
4. Specialized Robots
For environments, we offer customized materials and designs:
High-temperature versions: Ceramic bearings and 250°C-rated insulation suit foundry robots handling molten materials.
ATEX-certified explosion-proof motors: Spark-free BLDC drives for oil/gas inspection robots.
Submersible thrust systems: Titanium alloy gearboxes and waterproof magnetic encoders power underwater exploration robots.
5. Flexible Manufacturing Systems (FMS)
For rapid product changeovers, BLDC geared motors enable:
Modular design: ISO 9409-compliant flanges allow plug-and-play end-effector swaps.
Software compatibility: EtherCAT/CANopen protocols ensure seamless integration with KUKA, FANUC, and other controllers.
Multi-mode presets: DRV8316 driver chips enable online switching of speed-torque curves for drilling, polishing, etc.
6. Technical Selection Guidelines
As a manufacturer, we recommend evaluating needs based on:
Load profile: Calculate continuous/peak torque and select gear ratios (e.g., 1:100+ for heavy payloads).
Control requirements: Use 17-bit absolute encoders for precision positioning; opt for open-loop FOC control in speed-only scenarios to reduce costs.
Environmental factors: Choose liquid-cooled LRPX series for high temperatures; specify IP69K sealing for dusty environments.
Lifecycle cost: BLDC motors have higher upfront costs but reduce 5-year TCO by ~40% due to maintenance-free operation (no brush wear).
As a manufacturer of BLDC geared motors, we leverage decades of technical expertise and industry insights to explain how BLDC geared motors excel in industrial robotics. Our portfolio spans 3W compact joint motors to 10kW heavy-duty modules, with customizable gears (planetary, worm, harmonic) and shaft types (hollow, keyed, flanged).
