£1,099.00
The Unitronics UMM-0020EAB-B5 is a high-performance AC servo motor with integrated holding brake designed for demanding motion control applications requiring precise positioning, responsive torque delivery and reliable speed regulation. As part of the advanced Unitronics B5 Servo Motor Series, it is engineered for machine builders, OEM manufacturers and industrial automation professionals seeking accurate and dependable motion performance.
Featuring a high-resolution 23-bit absolute encoder, the motor delivers exceptional positioning accuracy and repeatability. Its low-inertia design enables rapid acceleration and deceleration while maintaining precise control, making it ideal for dynamic applications where responsiveness and productivity are critical.
With a rated output power of 2.0 kW and compatibility with 400 V three-phase servo systems, the UMM-0020EAB-B5 is ideally suited for robotics, packaging machinery, material handling systems, automated assembly equipment and high-speed industrial production machinery. The integrated 24 V DC holding brake provides secure load retention during power loss or shutdown conditions, making it particularly suitable for vertical-axis applications and positioning systems.
Servo motors such as the Unitronics UMM-0020EAB-B5 continuously monitor encoder feedback and automatically adjust motor performance in real time. This enables highly accurate positioning, responsive torque delivery and stable speed regulation while helping improve machine productivity, efficiency and repeatability.
The integrated holding brake enhances operational safety by maintaining shaft position when power is removed. Combined with Unitronics servo drives, PLCs and motion control software, the motor forms part of a complete automation platform that simplifies commissioning, diagnostics and machine integration. Unitronics servo systems feature high-resolution absolute encoder technology, automatic communication setup and ready-made motion functions for rapid deployment.
