Product Description:

Bosch Rexroth Indramat manufactures the MHD112A-024-NP0-LN in its MHD Synchronous Motors series. It is a servo motor intended for closed-loop industrial axes where consistent torque and position tracking are required for packaging, material-handling, and machine-tool tasks. Digital servo feedback in HSF format supplies high-speed encoder data, and the relative position is measured optically for fine interpolation by the drive.

The motor delivers a continuous standstill torque of 15.0 Nm, allowing stable holding force during low-speed processes. Protection against dust and water jets is classified as IP65, so the housing can be mounted in washdown or dusty zones without extra covers. Heat is removed through liquid cooling, which lets the windings reach rated output without relying on ambient airflow. Position accuracy is held within ± 0.5 angular minutes, and operation is permitted from 0 to 40 °C. The winding code 024 identifies the electrical constants, and insulation class F supports winding temperatures up to 155 °C. The motor uses a keyed shaft with a shaft seal, comes without a holding brake, and has a left-side power connector for installations that route motor leads from that direction.

When stored, the unit tolerates temperatures from −20 to +80 °C, which helps protect the motor during transport and idle periods. Centering in the machine frame is achieved by a 130 mm pilot diameter, and the flange measures 192 mm square to fit standard IEC mounting patterns. Installation altitude is limited to 1000 m above MSL so cooling performance and insulation clearances remain within rating. Size 112 stator laminations with length code A provide the magnetic volume for the motor's torque output, and the liquid jacket is compatible with closed-loop chillers. The optical measurement method does not drift with temperature, which helps maintain encoder accuracy through normal service.
