Product Description:

The MHD112B-056-PP0-BN belongs to the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. This servo motor converts commanded drive current into precise rotary motion for positioning axes in automated assembly cells, material-handling gantries, and other industrial machines that depend on accurate closed-loop motion. Its housing, flange interface, and integrated encoder follow standardized series dimensions, which helps maintain consistent mechanical fit and stable feedback integration across compatible systems. It is suitable for applications that require consistent motion quality through repeated starts, stops, and direction changes.

At a standstill the motor delivers a continuous torque of 28.0 Nm, allowing it to hold loads such as index tables without overheating. Mounting is guided by a centering pilot of 130 mm and a flange size of 192 mm, which help keep the motor aligned with machine plates, couplings, or gearbox faces. Heat generated in the windings is removed through liquid cooling, supporting sustained operation at high current density during demanding duty cycles. The power leads exit on side B, which can simplify cable routing when the drive is positioned at the opposite end of the axis, and a keyed output connector provides a quick-disconnect interface for those leads.

The rotor transmits motion through a keyed shaft, which helps prevent slippage between the motor and the driven element during reversals or rapid acceleration. Multi-turn feedback is achieved with absolute digital servo feedback with more than 4096 revolutions, so the control system can retain position information after power cycling and resume operation with accurate rotor reference data. Because the motor is supplied without a holding brake, static load retention must be provided by external locking hardware or by drive torque when the application allows it. A shaft seal helps block coolant or dust, and the size 112, length B housing keeps overall inertia moderate for fast dynamic cycles.
