Product Description:

The MHD115A-058-NG0-AN is a servo motor from Bosch Rexroth Indramat in the MHD Synchronous Motors series. It translates drive controller commands into precise rotary motion so automated axes can accelerate, position, and hold loads with tight tolerance. In packaging lines, material handling cells, or CNC stations, the unit supplies controlled torque while returning position data that lets the drive regulate speed and orientation at every cycle. This closed-loop arrangement supports repeatable motion during rapid starts, stops, and steady running.

This motor develops a continuous standstill torque of 32.0 Nm, delivered through a plain shaft protected by a shaft seal. Heat is removed by liquid cooling, a housing feature that supports high power density while keeping the F-class insulation within limits during sustained operation. Protection against dust and water jets is rated IP65, and the frame uses a 180 mm centering spigot with winding code 058. Rotor position is monitored with Digital servo feedback (HSF), and power enters on side A through an output connector. The design omits a holding brake, so load retention at standstill must be provided by the drive or an external mechanism when required. Length code A and size 115 describe the package envelope used for this motor.

Environmental limits are also stated for storage and operation. The motor stores safely between -20 to +80 °C and operates from 0 to 40 °C, which helps preserve insulation and mechanical fit under normal industrial conditions. It may be installed up to 1000 m above mean sea level without derating. An optical measurement method working on a relative scale yields system accuracy of ± 0.5 angular minutes, supporting precise speed correction and position tracking. The feedback hardware is referenced to the 192 mm square flange, and the centering spigot helps maintain concentric alignment during mounting.
