Product Description:

Bosch Rexroth Indramat builds the MHD112B-048-NG0-AN servo motor for motion axes that need high torque density and accurate position control. It belongs to the MHD Synchronous Motors series and acts as an electromechanical actuator within industrial automation, converting drive currents into continuous shaft rotation for packaging, material handling, and CNC equipment. Its synchronous design supports coordinated motion on indexing tables, feed axes, and transfer systems that require responsive torque under changing loads. This makes the motor suitable for repeatable positioning, controlled feed motion, and synchronized axis movement in automated production cells.

The motor supplies a continuous torque of 28.0 Nm when the rotor is held stationary, giving machines predictable force for clamping or slow-speed feed tasks. Heat generated under this load is removed through liquid cooling, allowing the stator to remain within insulation class F limits during 100% duty cycles. The enclosure is graded IP65, so the windings remain protected against airborne dust and water jets encountered on the factory floor. Accurate mechanical alignment is simplified by a 130 mm centering diameter that matches standardized mounting bores. Rotor position is reported through digital servo feedback (HSF), enabling high-resolution closed-loop control from the associated drive.

Closed-loop accuracy reaches ± 0.5 angular minutes, supporting applications that index fixtures with tight repeatability. The motor can operate continuously within 0 to 40 °C ambient temperatures and may be stored from −20 to +80 °C without degradation. It is supplied without a holding brake, so any stationary load must be secured externally or by drive torque. A flange diameter of 192 mm provides a rigid interface for heavy gearheads, while a plain shaft with an integral seal helps prevent lubricant egress. The sealed shaft area helps protect the bearing area in installations exposed to splash or airborne contamination. Relative position detection is optical, power leads exit on side A through an output connector, the winding code is 048, and installation is permitted up to 1000 m above mean sea level.
