Product Description:

The MHD112B-048 is a synchronous servo motor developed by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It operates as a rotary actuator in automated assembly cells, translating inverter current into controlled torque and speed for coordinated multi-axis motion. Typical duties include indexing conveyors, tool spindles, and pick-and-place axes where accurate positioning and rapid acceleration are required for reliable cycle execution. Its synchronous design supports repeatable motion when the motor is paired with a compatible feedback and drive system.

A 130 mm centering diameter on the front face aligns the housing precisely with machine frames, reducing radial runout during rotation. The mounting interface is completed by a 192 mm flange that provides the bolt circle needed to withstand torsional loads without additional brackets. Under continuous excitation, the motor can deliver 28.0 Nm continuous torque at standstill, allowing stationary clamping or holding functions without overheating. The size 112 frame indicates the motor envelope and thermal capacity. Electrical behavior is set by winding code 048, which matches the coil characteristics to compatible drive settings across the intended speed range.

The motor uses a length B housing, which gives it a medium axial build that balances torque output with manageable mass on moving machine axes. It is intended for use with Bosch Rexroth Indramat drives, and motor data for the MHD Synchronous Motors series is commonly supported by compatible controls. The layout also leaves room around nearby couplings, guards, and machine members when installation space is limited. This format suits transfer axes and spindle-related motion where stable acceleration is needed without adding unnecessary load to lightweight structures.
