Key Features
- Higher torque: torque density can reach 37.85 N.m/kg; power density can reach 511.04 W/kg (data comes from Xiaomi Lab).
- Quick response: optimized motor control algorithm; accurate and fast closed-loop speed and position.
- Precision gears: gear components adopt high-precision machining technology and complex surface treatment technology.
- Quick-release design: outlet plug adopts a quick-release design to facilitate modular use and quick maintenance.
- Temperature monitoring: self-developed temperature monitoring system and protection algorithm make motor operation safer and more reliable.
- Integrated design: integrates reducer, motor, and driver; reducer and electromagnetic design are optimized; heat dissipation system is improved to increase heat dissipation speed.
- Algorithm simulation: simulation algorithm accurately simulates and removes weight redundancy; after simulation and testing, the final optimized motor weight is reduced by 20% compared to the initially designed motor (weight redundancy is a comparison with itself).
- Exquisite workmanship: achieve high slot fill rate; the inner ring gear is injection molded in the mold, with a slot filling rate of 85%.
- Materials/process: stator and rotor adopt high-quality material selection and iron core coating process; stator cables are dipped in paint and the iron core is plastic-coated to upgrade heat dissipation and provide durability.
- Protection algorithm: self-developed motor protection algorithm operates stably and cooperates with an optimized heat dissipation system to ensure stable operation.
- System-level magnetic circuit optimization: improves magnetic flux utilization and stability and simulates various load conditions; based on an ultra-high computing power simulation platform and “digital twin motor efficiency”.

Details

CyberGear is a compact integrated servo micromotor built for robotics joints and other high-torque, space-limited actuators.

Key design points include fast closed-loop control, precision gearing, a quick-release outlet plug, and temperature monitoring features.

An integrated reducer, motor, and driver layout helps keep the actuator compact while supporting responsive speed and position control.

Protective control algorithms and system-level magnetic circuit optimization are used to support stable operation under load.

The torque–speed curve helps with sizing the motor for your target RPM and required output torque.

Overload-time data provides a quick reference for short-duration peak torque use cases versus sustained output.

Magnetic circuit simulation is used to optimize efficiency and stability across different load conditions.

Specs and typical uses are summarized here, including CAN communication, 24VDC input, and a 14-bit encoder.
