Product Description

The 630NHG4B-690 motor paired with an NHG4B gear reducer delivers a high-performance 690V industrial gearbox solution optimized for heavy-load applications. Designed with a three-phase 690V power input, it integrates directly with modular drive systems and supports industrial communication protocols like Modbus or Profibus. Operating within a wide voltage range of 600-750V and temperature tolerance of -20°C to +60°C, it suits demanding sectors like mining, material handling, and energy production. This gearbox features a compact design with enhanced torque density, enabling precise motion control in space-constrained environments. While its primary limitation lies in weight-to-power ratio for ultra-high-speed operations, its rugged construction ensures longevity under extreme conditions. The unit excludes onboard batteries or displays, focusing purely on mechanical reliability, and supports sensor integration for distance monitoring up to 10 meters via auxiliary interfaces.
