Product Description:
The MHD095B-058-PG1-BN is a servo motor built by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for closed-loop drive systems, the unit converts drive current into controlled rotary motion. It is suited for positioning axes, packaging machinery, and general automation tasks where accurate speed and position control are required. The motor is typically used with a compatible servo drive so commanded motion can be corrected continuously under changing load conditions.
Its continuous torque at standstill reaches 17.5 Nm. The housing uses liquid cooling to remove heat from the stator windings, which use winding code 058, and this helps stabilize temperature during sustained duty. Integrated holding hardware delivers 22.0 Nm of brake torque to lock the rotor when power is removed. For the mechanical interface, the motor offers a 130 mm centering diameter and a flange size of 140 / 150 mm for direct coupling to gearboxes or machine frames. Protection against dust and water jets is rated at IP65, and the plain shaft exits the housing without a keyway to minimize backlash. Digital servo feedback with an integrated encoder supplies absolute position information over more than 4096 revolutions, and the drive receives this data in real time for closed-loop control.
The motor can operate between 0 to 40 °C, while storage conditions extend to −20 to +80 °C. During operation, the feedback chain delivers repeatability within ± 0.5 angular minutes, which supports precision indexing. Mounting altitude can reach 1000 m above mean sea level, and the windings use Class F insulation with a 155 °C thermal limit. Power and feedback cables connect through a connector on side B, which keeps both connections grouped at one end of the motor. A shaft seal helps block coolant ingress at the plain shaft, and the motor has size 095 with length code B for the corresponding frame format in this series.
