Description

The CubeMars RI100 KV105 is a high-performance frameless brushless DC motor engineered specifically for advanced robotic systems requiring precise motion control. Its compact, lightweight design facilitates direct integration into robotic joints, exoskeletons, and articulated arms where space and weight are critical constraints.

Built with a 14-pole-pair delta winding configuration, the motor delivers excellent torque density and thermal efficiency. The integrated Hall sensor enables accurate rotor position detection, which is essential for implementing high-performance Field-Oriented Control (FOC) algorithms, resulting in superior smoothness, responsiveness, and low-speed control.

Key Features

  • Frameless BLDC inrunner design for direct integration into robotic joint assemblies.
  • Integrated Hall sensor for precise rotor position feedback and closed-loop control.
  • Engineered for optimal performance with Field-Oriented Control (FOC) drivers.
  • High-grade industrial insulation ensures reliable operation in demanding environments.
  • Robust construction with a high torque-to-weight ratio for dynamic robotic applications.
  • Wide operating voltage range (24–48V) supports various power system architectures.
  • Low phase resistance and inductance for efficient power delivery and thermal management.

Applications

  • Precision robotic joints for collaborative robots (cobots) and industrial robotic arms.
  • Actuation systems for exoskeletons and powered human-assistive devices.
  • Leg joint motors for quadruped and bipedal walking robots.
  • High-torque, low-speed direct-drive applications in automation and CNC equipment.
  • Custom UAV gimbal and payload positioning systems requiring smooth, precise rotation.

Frequently Asked Questions

What is the primary application for the CubeMars RI100 KV105 motor?

The RI100 KV105 is engineered as a frameless inrunner motor specifically for high-precision robotic joint applications. It is ideal for integration into collaborative robots (cobots), exoskeletons, robotic arms, and quadruped legs where compact size, high torque density, and smooth, controlled motion are required.

Does this motor require a specific type of electronic speed controller (ESC)?

Yes, this motor is optimized for use with Field-Oriented Control (FOC) ESCs. The integrated Hall sensor provides the necessary rotor position feedback for the FOC algorithm. It is not compatible with standard sensorless BLHeli_S or BLHeli_32 ESCs used in typical FPV drones.

What is the operating voltage range, and how does performance change across it?

The motor supports a wide voltage range from 24V to 48V DC. Performance scales with voltage: higher input voltage allows the motor to achieve higher RPM (No-Load Speed of 4368 RPM at 48V vs. 2184 RPM at 24V) and can deliver peak torque (4.95 Nm) more efficiently. The rated torque of 1.76 Nm is maintained across the range with proper current limiting.
