Power-Off Brake
The core technology of the product lies in the harmonic integrated joint module, featuring a drive-control integrated design. The inner rotor structure enables hollow cabling, while diversified model options including 11, 14, 17, 20, 25, 32 and 40 series ensure flexible applications. With a compact and miniaturized profile and low power consumption, it adopts a pin-type brake mechanism that triggers mechanical locking instantly upon power loss, with an action time of less than 10ms.
The dual steel wheel design, integrating cross-roller bearings with steel wheels, reduces axial space occupation. By meshing two steel wheels with one flexspline, it mitigates stress from flexspline deformation, achieving smooth operation, high efficiency and positioning accuracy up to 20 arcseconds.
