£1,821.75
The Unitronics UMM-0030EAB-B5 is a high-performance AC servo motor with integrated holding brake designed for precision motion control in demanding industrial automation applications. As part of the advanced Unitronics B5 Servo Motor Series, it delivers exceptional positioning accuracy, rapid response times and dependable torque performance for machine builders, OEM manufacturers and automation engineers.
Featuring a high-resolution 23-bit absolute encoder, the motor provides outstanding feedback accuracy and repeatability. Its low-inertia design enables rapid acceleration and deceleration while maintaining precise control, making it ideal for high-speed automation systems requiring smooth and accurate motion performance.
With a rated output power of 3.0 kW and compatibility with 400 V three-phase servo systems, the UMM-0030EAB-B5 is ideally suited for robotics, packaging machinery, material handling systems, automated assembly equipment and 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-0030EAB-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 HMI systems, the motor forms part of a complete automation platform that simplifies commissioning, diagnostics and machine integration. Unitronics servo systems feature automatic setup, high-resolution encoder technology and comprehensive motion control capabilities.
