Product Description:
The MHD112A-058-NP0-AN belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a frame size 112 servo motor intended for closed-loop positioning and velocity tasks in industrial automation lines that rely on permanent-magnet synchronous technology. This type of motor is commonly used where accurate speed regulation and repeatable positioning are required over changing load conditions. The motor integrates digital servo feedback of the HSF type so the drive controller can read rotor angle quickly, and its relative position is detected optically for high-gain motion loops. That feedback arrangement supports stable control response during rapid acceleration and deceleration. A keyed shaft transmits torque to the load, and a shaft seal is fitted to limit lubricant escape in enclosed installations.
The stator uses Class F insulation, and winding code 058 provides a continuous standstill torque of 15.0 Nm. Heat is removed through liquid cooling, allowing full torque delivery while the housing maintains an IP65 enclosure rating. The mechanical interface uses a 130 mm centering diameter and a flange that measures 192 mm, giving predictable alignment on standardized mounting surfaces. Power conductors exit toward side A through an output connector, which supports single-sided cable routing and simplifies cable entry planning. The motor is supplied without a holding brake, so static load retention must be handled by external clamping or maintained drive current.
For field use, the device operates in ambient air from 0 to 40 °C, and it can be stored between -20 to +80 °C when it is not in operation. Feedback resolution supports a system accuracy of ± 0.5 angular minutes, which pairs with the relative measurement method for fine contouring tasks. Installation is permitted up to 1000 m above MSL, after which derating rules apply. Indoor industrial installations with controlled cooling circuits can operate within these limits. The A length keeps the motor compact, and the keyed shaft design is suitable for rigid couplings.
