Motor Velocity Field Chart
Thousands of times of velocity streamline calculation Ensure the stability and reliability of the motor in any scenario

Highly Integrated
It integrates motor body and controller, and thus removes cumbersome connecting lines.
Oulet connectors support plug-and-play function.
Quick disassembly design makes maintenance easier
The enclosed design can prevent dust from entering into the motor

Optimize Magnetic Circuit Design
Improve magnetic flux utilization. The back EMF is sinusoidal. Low cogging torque

 

Super large industrial grade

High precision and long life

Motor perception feedback: torque, angle, angular

speed, angular acceleration, temperature
Motor control command: torque, angle, angular

speed, stiffness, damping

 

Temperature Detection Sensor
Motor with temperature detection sensor
It can effectively prevent the motor from being damaged due to abnormal temperature

 

High Quality Electromagnetic Wire And Iron Core Technology

  • The electromagnetic wire adopts the technology of dipping paint to make the motor temperature get better heat dissipation
  • Single stranded copper wire. Reduce copper consumption and current interference between copper wires. At the same time, make the motor more beautiful
  • The iron core adopts electrophoresis and high temperature resistant coating technology. It can pass the 48 hour salt spray test. Super rust proof, temperature resistant and pressure resistant
  • Choose 0.2mm silicon steel sheet material to reduce iron consumption

 

FOC Control Characteristic Curve
FOC control. Torque fluctuation is small. Low noise. Smoother operation

 

Reasonable Body Design

  • Ultra thin design
  • Use every 0.1 mm space accurately
  • Planetary reducer with limit optimization
  • Multi-function. Small fuselage. Weight only 605g
