Product Description:

The MHD131B-024-PP0-AN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is used in closed-loop drive systems that need high torque density and reliable position feedback for material handling, packaging, and CNC axes. In these applications, the motor works with the drive to maintain commanded speed and position under changing loads. This supports coordinated motion where repeatable acceleration, deceleration, and positional accuracy are required across long operating cycles. No mechanical holding brake is installed, so position retention during power-off must be provided by the drive or an external clamp.

The mechanical interface uses a centering diameter of 250 mm and a flange pitch circle of 260 mm, allowing the motor to seat precisely on standardized machine mounts. At standstill it can generate 48.0 Nm of continuous torque, which provides a steady reference for gear ratios and driven loads at low speed. Rotor position data comes from digital servo feedback, which sends absolute angle information to the controller for accurate speed regulation. This helps the controller maintain smooth response during low-speed positioning and changing load conditions. The motor uses liquid cooling, which removes heat from the stator jacket and supports a stable winding temperature during sustained duty.

The frame uses motor size 131 and length code B to balance inertia with rated power in the series. The encoder supports absolute position over more than 4096 revolutions, so homing after power cycles is unnecessary. Electrical characteristics follow winding code 024 and match compatible Indramat drive modules. Torque is delivered through a keyed shaft, and a shaft seal helps keep coolant and lubricants away from the bearing area. The power connector is on side A, which helps keep cable routing clear of adjacent axes and other moving parts.
