Product Description:

The MHD112B-058-NP0-BN servo motor is manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for integration with digital drive controllers in industrial automation, where precise torque and speed regulation are required for indexing tables, gantry axes, or feed drives. By converting controlled AC power into mechanical rotation, the unit serves as the primary mover in closed-loop motion stages. This type of motor is well suited to applications that require repeatable positioning and stable response during changing load conditions.

At standstill, the motor can deliver a continuous torque of 28.0 Nm, allowing it to support loaded axes without external gearing. The motor is supplied without a holding brake, so static holding force must be provided by the drive or by external mechanics. Thermal energy is transferred to a machine coolant circuit through its liquid cooling housing, which helps manage winding heat during extended duty cycles. Mounting is achieved with a square flange that measures 192 mm across, providing a rigid interface for large-frame machinery. Rotor position is reported to the drive by digital servo feedback (HSF), which supports fast signal processing in closed-loop control. Output torque is transmitted through a keyed shaft, making it suitable for couplings, pulleys, or pinions that require positive torque transfer.

The stator spigot has a centering diameter of 130 mm, helping align the frame concentrically with the machine interface. Power and ground conductors are routed through an output connector on side B, which can simplify cable routing when several axes are installed close together. The motor uses winding code 058, which corresponds to specific drive current ratings for this model. A shaft seal is fitted at the rotary output to help limit coolant or contaminant ingress into the bearing area. Relative position detection is supported, which helps the drive maintain accurate motion control during operation.
