Product Description:

The MHD112D-027-PG3-LN servo motor is built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts drive current into controlled rotary motion for positioning tables, gantry axes, and packaging spindles in industrial automation. Digital servo feedback with an integrated absolute encoder closes the loop with compatible Rexroth drives, supporting accurate speed regulation and repeatable positioning during frequent starts and stops. The plain shaft mates directly to couplings or gearboxes, and the size 112 housing provides a high torque reserve for demanding axis loads. This makes the motor suitable for applications that must reverse direction quickly while maintaining stable motion under changing load conditions. The left-hand power connector also helps simplify cable routing where cabinet space is limited.

At standstill, the unit delivers 48.0 Nm of continuous torque, maintaining force during creep feeds or dwell phases. Heat leaves the windings through liquid cooling, which helps the motor sustain output without relying on external airflow around the housing. This cooling method also reduces dependence on cabinet ventilation when the axis runs at low speed for extended periods. The enclosure carries IP65 protection, and a shaft seal helps keep splash and dust away from internal components. A 130 mm centering pilot and 192 mm flange support accurate mounting on the machine face and help maintain alignment with the driven load. Class F insulation allows elevated winding temperatures, while the 027 winding and D length arrangement suit installations that need strong torque in a compact axial depth.

Optical scanning supports absolute feedback over more than 4096 revolutions and keeps system error within ±0.5 angular minutes. Because the feedback is absolute, the connected control can retain position information through power cycling without requiring an immediate reference move. A spring-applied brake provides 70.0 Nm of holding torque, helping keep vertical or suspended loads in place when input power is removed. The motor operates in ambient air from 0 to 40 °C and can be stored between –20 and +80 °C. Installation is permitted up to 1000 m above mean sea level, and the sealed shaft arrangement helps limit lubricant escape at the drive end.
