The Bosch Rexroth Indramat MHD071B-061-NP1-UN from the MHD Synchronous Motors series is a precision-engineered servo motor designed for demanding automation tasks. This MHD071B-061-NP1-UN model features a compact motor size 071 frame with a winding code 061 and a motor length B housing, offering high torque density in a streamlined form factor. Its four number of pole pairs 4 enable a maximum speed of 6000 min-1, and the keyed shaft with a centering diameter of 95 mm ensures accurate rotor alignment under dynamic loads. Weighing just 8.8kg, this motor balances robust performance with manageable mass for high-density installations.

Reliability is central to the MHD071B-061-NP1-UN’s design. Liquid heat dissipation through the housing cooling type liquid cooling system and a thermal time constant of 45min keep winding temperatures stable during extended operation. A continuous torque at standstill of 8.0 Nm provides firm holding capability, augmented by the integrated holding brake delivering holding brake torque of 5.0 Nm for safe stops and position retention. The shaft seal protects internal components from contaminants, while the turnable power connection direction turnable within a range of 270° allows flexible cable routing in tight control cabinets. High-resolution positioning is achieved via the digital servo feedback (HSF) encoder type and a relative type of position detection, ensuring precise synchronization in multi-axis setups.

Commissioning at altitude is simplified by the motor’s ability to operate up to maximum setup height of 1000m above MSL, and the robust shaft design keyed shaft delivers secure torque transmission under rapid acceleration. Whether deployed in packaging machinery, CNC systems, or industrial robotics, the MHD071B-061-NP1-UN delivers consistent, tightly regulated motion control with advanced thermal, mechanical, and electrical safeguards built in.
