Product Description:
The MHD112A-024-PG1-BN belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a servo motor intended for closed-loop motion axes in automated machinery, where the integrated digital feedback works with a drive controller to maintain commanded position and velocity. The optical encoder tracks rotor position, and its feedback data helps the axis respond accurately during acceleration, deceleration, and steady-state operation.
This motor delivers a continuous standstill torque of 15.0 Nm, allowing static load holding without overheating. The housing meets the IP65 ingress rating, so dust and low-pressure water jets do not reach internal windings. Heat generated in service is removed through liquid cooling, which keeps the frame temperature stable and supports higher duty cycles than air-cooled units. A square mounting interface with a 192 mm flange aligns the stator to gearboxes or machine plates. A holding brake rated at 22.0 Nm secures vertical loads during power loss. Electrical insulation is built to class F standards, giving the stator varnish a 155 °C thermal limit. A 130 mm centering diameter positions the motor concentrically, the plain shaft transmits torque without a key, and the power connector is oriented on side B for straightforward cable routing. The plain shaft is suited to friction-based couplings that do not require a keyway.
Total system precision is supported by a feedback chain that reaches ± 0.5 angular minutes, and absolute position detection over 4096 revolutions eliminates homing routines after shutdown. Safe storage is permitted from -20 to +80 °C, while normal operation must remain within 0 to 40 °C so the coolant can manage losses effectively. Installation is permitted up to 1000 m above sea level without derating. A shaft seal helps keep coolant or oil away from the bearing journal.
