Pysical Human-Robot Interaction by using 6 – Phase BLDC Motor for Improving Torque Density of Robot Actuator ​

To solve the problem of current general robots that cannot absorb shock due to the limitations of the motor’s reducer, we developed a reducer using a high torque density motor (15 times the torque density of other products) and an ultra-low friction cycloid tooth shape.

By maximizing torque density through multi-phase control of the motor, effects such as reduced torque ripple, increased stability, and improved efficiency can be achieved.
