Product Description:

The MHD131D-024-NP0-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Designed for numerically controlled axes and automated handling systems, the unit converts drive current into rotary motion while returning position data to the controller. In automated machinery, it supplies commanded torque to move loads, maintain setpoints, and support accurate axis response during repeated motion cycles. Its feedback-driven operation suits indexing tables, gantries, and transfer units where smooth torque delivery and consistent positioning behavior are important.

The motor sustains a continuous stall torque of 160 Nm, enabling heavy feed drives to remain clamped or accelerate without exceeding thermal limits. Heat is removed by liquid cooling, so circulating coolant carries loss power away from the stator and supports high torque density in the housing. The motor is sealed to IP65, which helps keep dust and hose-directed water away from internal parts. Rotor position is measured by digital servo feedback (HSF), an optical system that sends high-resolution incremental data to the drive for stable speed and position control. Combined component tolerances keep system positioning error within ± 0.5 angular minutes, supporting contouring and interpolation tasks that require very fine repeatability.

A centering pilot diameter of 250 mm aligns the motor on the machine interface and helps keep the mounting position stable during installation. The motor operates in ambient air from 0 to 40 °C, and the insulation system uses class F materials for continuous-duty service. Torque is transmitted through a keyed shaft, and the fitted shaft seal helps reduce contaminant entry at the output end. The unit is supplied without a holding brake, so any static holding function must be provided elsewhere in the axis system. Electrical power reaches the stator through a connector on side B, which can simplify cable routing in machines with side-entry harness layouts.
