Detailed answers to common questions asked by hardware engineers and sourcing professionals.
To select the optimal gear ratio, we balance target output speed, required torque, and motor efficiency limits. For high-torque applications, we typically recommend a planetary gearbox over a spur design. Planetary layouts distribute load across multiple gear points, providing greater torque density and high efficiency (typically 80-90%) in a compact size.
Our standard planetary gearboxes have a backlash range of 1° to 1.5° (60 to 90 arcminutes). For high-precision applications like robotics, we can offer custom gearboxes with backlash reduced to ≤15 arcminutes through optimized gear tolerances and specialized assembly techniques.
For continuous duty, we recommend using Brushless DC (BLDC) motors, which generate less heat. We also use high-temperature windings, thermal paste interfaces, and housings with integrated heat sinks to manage thermal dissipation. Additionally, our lubricants are selected based on the operating temperature profile to prevent degradation.
Customization options include motor voltage, output speed, torque profiles, output shaft configuration (D-cut, cross-drilled, splined, or helical), encoder type (magnetic/optical), wire harness termination, and gear material selection (hardened steel, brass, or engineering plastics for noise reduction).
