Instant Burst of Power

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

Optimize the Magnetic Circuit Design

Improve the utilization rate of magnetic flux, and sinusoidalize the reverse potential, low Cogging Torque.

Motor Streamline Diagram

Thousands time of motor streamline calculations guarantee the stability and reliability of the motor in any state of motion.

Temperature Monitoring Sensor

The motor has its own temperature monitoring sensor to effectively prevent the motor from being damaged due to temperature abnormalities.

FOC Control Characteristic Plot

FOC control, low torque ripple, low noise, smoother operation.
