Product Description:

The MHD112C-058-NP0-AN belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a servo motor intended for closed-loop industrial axes where high positional repeatability and continuous duty are required. The keyed shaft transfers rotary power to gearboxes or direct-drive loads, while the shaft seal helps keep lubricant in place and limits contaminant entry around the bearing area. A relative position system, read optically by the integrated encoder, allows the drive to track motion after homing and then monitor shaft movement during normal operation. This arrangement suits automated handling and positioning systems that need consistent response during repeated start-stop cycles.

The motor supplies a continuous standstill torque of 38.0 Nm, which allows it to hold load at zero speed when the drive remains energized. With a housing rated at IP65, the windings and bearings are protected from dust and low-pressure water jets. Internal coolant channels use liquid cooling, removing thermal energy so the stator can deliver full torque in enclosed machine spaces. A centering pilot of 130 mm aligns the frame concentrically on machine faces, helping support accurate mechanical installation. Rotor feedback is provided by a Digital servo feedback (HSF) encoder, giving the drive high-speed phase information for dynamic current control and stable motion regulation.

The mounting interface is a square flange measuring 192 mm, and system accuracy is specified at ± 0.5 angular minutes for fine indexing on coordinated axes. Safe storage is permitted between -20 to +80 °C, while continuous operation must stay within 0 to 40 °C. Class F insulation permits winding temperatures up to 155 °C, and the motor can be installed up to 1000 m above mean sea level without derating. The motor has length C, size 112, winding code 058, and a power connector that exits toward side A. It is supplied without a holding brake, uses an optical measurement method, and retains a shaft seal.
