Instant Burst of Power

It can be adapted to a variety of large-load mechinery and equipment such as foot robots, with greater torque and more stability. The output maximum torque is 33.5N.m, wich easy achieves a powerful instantaneous explosive force, and the maximum joint speed of 21 rad/s makes the instantaneous speed beyond imagination.

 

High-quality Electromagnetic Wire and Iron Core Process

  • The electronic wire adopts dip paint technology to better dissipate heat from the motor temperature.
  • The winding of a single strand of copper wire reduces copper wear and reduces the current interference between copper wires while making the motor more beautiful.
  • The iron core has electrophoresis and high-temperature coating process that can pass the 48 hours salt spray test with the superior rust resistance and pressure resistance.
  • The imported 0.2 mm silicon steel sheet material is selected to reduce iron consumption.

 

Highly Integrated
Set the motor body and the controller in one, minus cumbersome connecting lines, plug to achieve plug and play quick disassembly structure design, easier maintenance, closed design, to avoid debris into the motor inside.

  • Oversized Industrial Grade Crossed Roller Bearings
    Resistant to axial impact, high precision, and long life.
  • Real-time Reading of Sensor Data
    Motor Sensing Feedback: Torque, Angle, Angular Velocity, Angular Acceleration, Temperature
    Motor Control Instruction: Torque, Angle, Angular Velocity, Stiffness, Damping

 

Brushless High Speed Motor Strong Driving Force,
Longer Service Fife

It provides stronger driving force. The maximum torque of 23.7 NM and the maximum speed of 30 rad/s can be reached at a reduction ratio of 6.33 (Note: Measured at 24°C).
Thousands of times of motor streamline calculation ensure the stability and reliability ot the motor in any moving state

 

Excellent in Black Technology
Professional Magnetic Circuit Design

Improve the flux utilization, sine the counter electric potential, low Cogging Torque

 

Intelligent with Real Strength
Temperature Monitoring Sensor

The motor comes with its own temperature monitoring sensor which can effectively prevent the motor from being damaged due to abnormal temperature
