PRODUCT ADVANTAGES

  1. It offers significant torque in a compact package.
  2. It boasts high precision, with absolute positioning accuracy kept within 20 arc seconds.
  3. It is robust against environmental conditions, rated at IP65 for protection.
  4. It is designed for zero maintenance, eliminating the need for lubricant replacement throughout its service life.
  5. It is durable, with consistent accuracy sustained even after extensive use exceeding 15,000 hours.

PRODUCT DESCRIPTION

Fundamental high-voltage model, equipped with a standard hollow shaft, featuring a single encoder, and lacking a braking system.

This device is equipped with an integrated dual absolute encoder system and a dual-loop positioning control mechanism, featuring a 16-bit absolute encoder for the output shaft. It offers high repeatability at ±7 arc seconds and absolute accuracy up to ±15 arc seconds, while maintaining the actual absolute position and multi-turn count even when the power is turned off.
The internal friction brake ensures a smooth and stable stopping mechanism. It operates without any gaps or backlash, eliminating the need for adjustment upon power-up. This brake is wear-resistant and can serve as an effective emergency stop feature.
