Product Description:

The MHD115B-024-NG0-AA servo motor is produced by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. As a permanent-magnet AC actuator, it converts electric commands from a drive controller into mechanical rotation for positioning, feeding, or indexing tasks in automated machinery. The motor is supplied without an integral holding brake, relies on natural cooling at the housing, and provides digital servo feedback to the drive for closed-loop control of velocity and position in production lines, packaging units, and material-handling axes.

At standstill, the rotor can deliver a continuous torque of 50.0 Nm, giving the drive enough reserve for static loads such as clamps or vertical axes. The housing carries a sealing system rated to IP65, meaning dust-tight construction and resistance to low-pressure water jets, so the unit may be mounted directly on machines without extra enclosures. Heat is removed through natural convection, so unobstructed airflow around the fins is required within the specified operating range of 0 to 40 °C. A plain shaft transmits motion to couplings while minimizing runout.

Mechanical interfaces are standardized: the centering pilot measures 180 mm in diameter and mates with a flange that is 192 mm square, matching machine interfaces for size code 115. The optical encoder provides relative position data with a system accuracy of ± 0.5 angular minutes, supporting high-precision servo loops. Thermal endurance is reinforced by an insulation system classified as Class F, permitting winding temperatures up to 155 °C during intermittent overloads. The motor tolerates storage conditions from -20 to +80 °C, includes a shaft seal to limit ingress, and its power leads exit toward side A through an output connector. Installation is limited to 1000 m above mean sea level.
