Product Description:

The MHD112B-048-NG1-AN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for closed-loop motion tasks, it couples a stator winding and permanent-magnet rotor so that controllers can command position and velocity with minimal lag. The motor is cataloged under size 112 and winding code 048, giving it electrical constants suited to medium-inertia axes in automated machining centers, packaging lines, and general material handling. In these installations, the unit interfaces directly with intelligent drive modules to generate repeatable torque while maintaining tight speed regulation.

Its continuous torque at standstill reaches 28.0 Nm, a level sustained through the motor’s jacket-based liquid cooling system that removes heat from the windings. The enclosure carries an IP65 rating, so dust ingress and water jets do not compromise operation on the factory floor. Mechanical connection is made with a 192 mm flange and a 130 mm centering diameter, while a plain shaft and shaft seal transmit motion without leakage. Rotor position is measured optically by the digital servo feedback (HSF) encoder, and this relative system feeds controllers through an output connector on side A. The motor length is coded B, and the insulation is class F. Power routing follows the same side-A connector arrangement, which simplifies wiring layouts.

It is delivered with a holding brake that applies 22.0 Nm of static torque to secure vertical or suspended loads when power is removed. Closed-loop accuracy is ± 0.5 angular minutes, allowing repeatable positioning across complex cycles. The motor operates reliably between 0 to 40 °C and can be stored from -20 to +80 °C without performance loss, which supports spares kept in uncontrolled warehouses. Installation height may reach 1000 m above mean sea level while maintaining the stated operating range.
