Instant Power
It begins with the LiveDrive™ Axial, the world’s highest performance direct-drive electric motor. With an axial magnetic alignment, the LiveDrive™ Axial delivers 3x torque-to-weight of other direct drive motors and 22x torque-to-inertia compared to best-in-class actuators, along with high precision and smooth backdrivability.
3X Torque
to Weight
It features a thin form factor and large through hole, providing a low weight and high-power solution for direct-drive applications and high-speed robotics.
