Key Features and Benefits
-
Precision Control and High Dynamic Response: The MHD071B-061-NG0-UN is equipped with a high-resolution multi-turn absolute encoder
Robust Construction and High Protection Level: Featuring an IP65 protection rating, this motor is effectively sealed against dust ingress and low-pressure water jets from any direction.
-
This makes it suitable for operation in challenging environments commonly found in industries like food and beverage, chemical processing, or metalworking, where exposure to coolants, washdowns, or particulate matter is possible.
-
High Overload Capacity: The motor is designed to deliver high peak torque (typically up to 3 times the rated torque for short periods).
-
This allows it to handle sudden load surges, overcome static friction during startup, and accelerate heavy loads efficiently without stalling, ensuring stability and reliability in dynamic applications.
-
High Efficiency and Energy Savings: The motor features an optimized electromagnetic design and high-quality materials that minimize energy losses.
-
This translates to reduced operating costs and less heat generation, contributing to a longer component lifespan and a lower total cost of ownership.
-
Flexible Integration and Compatibility: The motor supports various fieldbus protocols such as Profinet and EtherCAT.
- This flexibility allows for seamless connection to different industrial automation systems. Furthermore, its design ensures compatibility with Rexroth's drive systems, such as the IndraDrive family, simplifying system configuration and commissioning.
-
Ease of Maintenance and Diagnostics: The integrated absolute encoder eliminates the need for homing routines after power cycles, reducing downtime. Modern feedback systems often include diagnostic features that can help predict maintenance needs and quickly identify potential issues, enhancing overall equipment effectiveness (OEE).
