IntroductionThe load of the TDB-263-138-NH-RD direct-drive DD motor is mounted directly on the motor rotor, eliminating mechanical backlash and achieving very high servo stiffness. It integrates a high-end absolute encoder which improves efficiency and safety in automation systems. The direct coupling enables a more responsive control loop for precision equipment. Comprehensive support for custom designs and contract manufacturing (OEM/ODM) is available.
