Product Description:

The Bosch Rexroth Indramat MHD115A-058 is a servo motor in the MHD Synchronous Motors series. It is supplied as a rotary actuator for closed-loop positioning tasks in industrial automation. By translating regulated current from a drive controller into commanded shaft motion, the unit provides the mechanical link between electronic control and physical movement. This capability makes the motor suitable for synchronized machine axes where repeatable speed, acceleration, and position tracking are required to maintain process accuracy.

The mechanical interface starts with a centering diameter of 180 mm, providing concentric alignment between the motor housing and the machine frame. Surrounding that bore is a square flange that measures 192 mm across, establishing the bolt pattern that supports the frame. Within the MHD family, the frame is identified as size 115, which indicates the stator diameter and allows higher electromagnetic loading than smaller variants. Housing length code A marks the shortest envelope available for this size, reducing overall mass while preserving mounting geometry. At standstill, the motor can continuously deliver 32.0 Nm of torque without thermal overload, enabling stable holding force during dwell periods. Electrical characteristics are tied to winding code 058, which matches the impedance and voltage constant to compatible drive electronics.

The mounting interface supports rigid installation on the driven equipment, and the short housing helps conserve space around adjacent components. This layout also leaves more room for cable routing in compact machine assemblies. Adequate thermal capacity in the active material supports cyclic operation without exceeding the rated temperature rise. When connected to a digital drive inverter, the motor supports precise current control and stable velocity regulation across normal duty cycles.
