Product Description

This high-torque coreless servo is specially selected for MiraBot devices, delivering an excellent balance of ultra-low noise, high precision, and dependable load capacity.

The coreless motor design ensures smooth, responsive motion with exceptionally quiet operation, making it ideal for refined multi-axis movement. A full metal housing enhances durability while providing efficient heat dissipation, allowing stable performance even during extended use.

Built-in safety features further improve reliability, including Stall Protection (7 s) and Thermal Protection (>70 °C) to protect both the servo and your device under demanding conditions.

Fully compatible with MiraBot Lite, MiraBot S6, MiraBot S2+ (legacy models), and other DIY OSR-based devices, and easy to replace thanks to MiraBot’s modular design.

Why a 35 kg Coreless Servo?

During the development of MiraBot, we evaluated dozens of servo models from more than ten manufacturers, conducting repeated real-world tests focused on:

  • Noise level

  • Practical load capacity

  • Long-term durability

  • Stability and consistency under continuous operation

After extensive comparison, this 35 kg coreless servo proved to offer the most well-balanced overall performance.

Pursuing a single extreme specification—such as maximum torque—often leads to compromises in other critical areas like noise, lifespan, or control stability. Instead, this servo achieves a carefully tuned balance that performs reliably in real-world use.

For these reasons, it was selected as the standard servo solution for MiraBot devices.
