Product Description:

The MHD115C-059-PG0-AN is a servo motor produced by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. As a rotary actuator, it converts drive current from digital controllers into mechanical motion for positioning axes in automated machinery. An integrated digital servo feedback encoder supplies real-time rotor data to the drive, allowing closed-loop regulation of speed and angle during continuous duty cycles. This arrangement supports precise motion on equipment that requires repeatable starts, stops, and directional changes. It is intended for servo applications where accurate positioning and steady speed control are both required.

During operation, the motor delivers 70.0 Nm of continuous standstill torque, enabling stable holding forces for heavy loads. Heat generated by the windings is removed through liquid cooling, so rated output can be reached without temperature derating. The housing carries a IP65 protection rating that blocks dust ingress and water jets, allowing cabinet-free mounting. Position feedback is measured optically and resolved to ± 0.5 angular minutes, while the encoder supplies absolute (>4096 revolutions) position data to the drive for multi-turn reference tracking. The unit uses insulation Class F materials, follows winding code 059, and is supplied without a holding brake, so external clamping hardware is needed when power is removed.

The motor has a 180 mm centering diameter and a 192 mm square flange, which suit direct coupling to heavy gear stages. Frame size 115 and length C keep overall depth moderate, and the plain shaft includes a shaft seal to help prevent fluid intrusion along the journal. Power and feedback wiring exit toward side A through an output connector, which can simplify routing inside gantry or press columns. The motor may be installed up to 1000 m above mean sea level, operates in ambient temperatures from 0 to 40 °C, and can be stored from -20 to +80 °C without damage.
