Product Description:

The MHD112B-058 is an AC drive motor built by Bosch Rexroth Indramat in the MHD Synchronous Motors series. In automated assembly lines, it works with a matching drive controller to convert commanded current into precise rotary motion for gantry axes, indexing tables, and wrapping machines. The internal position sensor returns shaft data to the control loop, allowing the controller to maintain accurate speed feedback, controlled start-stop behavior, and stable torque response during changing loads. This makes the motor suitable for repetitive motion tasks that require consistent path control and timing across continuous operating cycles.

The mounting interface uses a centering diameter of 130 mm, which helps locate the housing concentrically in the machine frame and reduce runout. A flange size of 192 mm provides a rectangular mounting face with threaded holes arranged for standard fastening. This layout helps preserve shaft alignment when the motor is attached to machine plates or gearbox adapters. The motor can provide 28.0 Nm of continuous torque at standstill, so it can hold or move static loads without exceeding allowable winding temperature under rated conditions. The frame code 112 identifies the external stator diameter class used for this motor size.

The motor uses length category B, which gives a mid-length rotor stack that increases available torque while keeping inertia suitable for rapid acceleration. Its electrical setup uses winding code 058, which matches the current and voltage characteristics expected by compatible drive settings. Delivered as a dedicated servo motor, the unit includes encoder feedback and thermal monitoring for closed-loop operation. The shaft is prepared for direct coupling or gearhead connection, which supports integration into axes that need accurate rotary motion. These features support steady operation in applications that depend on repeatable movement and responsive speed control.
