Internal Product Review
The MHD112B-058-PP1-AN is a Bosch Rexroth Indramat servo motor with liquid cooling and IP65 protection. Absolute position detection beyond 4096 revolutions and digital servo feedback support precise closed-loop motion in demanding servo axes. The 22.0 Nm holding brake and 28.0 Nm continuous standstill torque make the motor an excellent choice for controlled, high-retention motion service.

Product Description:
The MHD112B-058-PP1-AN is a synchronous servo motor from Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. As a synchronous servo motor, it converts controlled electrical input into precise rotary motion for positioning and speed-regulated axes. It combines a keyed shaft with an output connector on side A to couple quickly to gearboxes or direct-drive loads. Motor size 112 and length code B give it a mid-range footprint that is common on packaging lines, pick-and-place gantries, and metal-cutting machines where rapid, closed-loop positioning is required.
The motor delivers a continuous standstill torque of 28.0 Nm, allowing it to hold static loads during controlled standstill. Heat generated at this load is removed by liquid cooling, so the motor can sustain output within its permitted operating range during continuous use. A sealing system rated IP65 with a shaft seal helps prevent dust and water jets from reaching the windings, while a centering diameter of 130 mm aligns the 192 mm flange accurately on the mounting face. Insulation class F gives the stator windings additional thermal margin, and storage is permitted from −20 °C to +80 °C. Installation is allowed up to 1000 m above mean sea level without derating.
For dynamic duty cycles, the integrated brake supplies 22.0 Nm of holding torque to secure vertical or suspended axes when power is removed. Absolute position tracking is maintained within ± 0.5 angular minutes when combined with the encoder’s Absolute (>4096 revolutions) capability, which supports repeatable homing over multiple turns. The rated ambient temperature range is 0 to 40 °C, and rotor position is monitored by an optical measurement system with digital servo feedback. This arrangement provides continuous position information for controlled motion and stable speed regulation.
