Performance & Structural Characteristics
It adopts resolver absolute multi-turn feedback, realizing battery-free absolute positioning and eliminating repeated zeroing after power failure. With IP65 protection grade, it resists dust and water splash, suitable for harsh workshop environments. The compact high-torque-density structure saves installation space, and the maintenance-free feedback system ensures stable operation under vibration and electromagnetic interference. Without built-in brake, it features shorter body length and lower cost, perfectly matching Rexroth servo drive systems for plug-and-play use. It supports 24-hour continuous industrial operation and complies with CE industrial safety standards.
