MHD041A-144-PP0-UN

The Bosch Rexroth Indramat MHD041A-144-PP0-UN model from the MHD Synchronous Motors series is a high-precision permanent magnet servo motor optimized for demanding industrial applications. Its robust construction integrates a Multiturn Motor Encoder and a Winding Code 144 to deliver consistent performance and reliable position feedback. This servo motor is designed for continuous operation in factory automation, packaging, printing, and paper-processing machinery, enabling rapid response times and precise motion control. Compact dimensions and a keyed driven shaft simplify mechanical integration while ensuring high torsional stiffness. Advanced materials and meticulous assembly processes contribute to the motor’s long service life and predictable maintenance cycles.

The technical specifications of the MHD041A-144-PP0-UN provide a comprehensive picture of its capabilities. It produces a Continuous Torque at Standstill of 1.3 Nm and features Pole Pairs 3 enabling smooth torque ripple across varying speeds. The motor incorporates Liquid cooling to maintain thermal stability under high load, and its International protection class IP65 rating ensures immunity from dust and water ingress. An integrated Digital servo feedback Encoder Type supports Type of Position Detection Absolute (>4096 revolutions) for accurate multiturn positioning. The flange measures 82 mm, with a Centering diameter of 50 mm and a Shaft Seal Yes arrangement for enhanced durability. Electrical connectivity is achieved via Power and feedback connectors, and the motor windings exhibit Winding inductivity 13.5 mH for optimized current control. Other critical parameters include a Characteristic motor speed of 7000 rpm, a Maximum installation elevation of 1000 m above MSL, and a Weight of 2.9 Kg.

Operationally, the MHD041A-144-PP0-UN delivers stable performance across a wide speed range, maintaining torque consistency up to its rated characteristic speed. The combination of liquid cooling and high inductance windings minimizes thermal drift during continuous duty cycles, while the IP65 housing allows installation in harsh factory environments. Absence of a brake (Holding Brake Without holding brake) reduces mechanical complexity and supports high-frequency start/stop operations without drag torque. The keyed shaft ensures secure coupling to gearboxes or driven machinery, and the motor’s compact length designation Motor Length A facilitates integration into space-constrained assemblies. Optimized electromagnetic design and pole pair configuration yield low vibration levels and accurate sinusoidal commutation.

For system integration, the MHD041A-144-PP0-UN interfaces seamlessly with Rexroth Indramat servo drives and controllers via standardized connectors, supporting real-time feedback loops and advanced motion algorithms. Its absolute multiturn encoder eliminates homing routines after power cycles, reducing downtime in automated production lines. The motor’s compatibility with liquid cooling circuits and robust IP65 enclosure make it ideal for applications in food processing, material handling, and CNC machinery where hygiene and washdown requirements apply. Overall, the MHD041A-144-PP0-UN is engineered to meet the exacting demands of modern factory automation and precision drive systems.
