Product Description:

The MHD112C-058-NG0-RN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It converts electrical energy into controlled mechanical rotation for positioning tasks on automated machines, material-handling axes, and packaging equipment where closed-loop speed and angle regulation are required. The motor uses winding code 058 with frame size 112 and motor length C, so it fits the intended drive combination and installation envelope. Position detection is relative rather than absolute, and the optical measurement method supports consistent feedback during repeated motion changes.

This model can deliver a continuous standstill torque of 38.0 Nm, giving the drive enough holding force for static loads without overheating. The enclosure has an IP65 protection rating, which helps keep dust and low-pressure water jets away from internal components. Heat is removed through liquid cooling, allowing high current density while keeping stator temperatures within F-class insulation limits. Rotor position is reported by a digital servo feedback (HSF) encoder, which improves loop bandwidth during rapid reversals. The optical scanning method supports a system accuracy of ± 0.5 angular minutes, and a flange diameter of 192 mm provides a standardized mounting interface for gearboxes or machine frames.

The centering pilot measures 130 mm in diameter, so alignment to mating shafts remains repeatable without additional sleeves. Rated operation is permitted from 0 to 40 °C, and storage is permitted from -20 to +80 °C. Installation is allowed up to 1000 m above sea level. Power enters from the right side through a molded power connector, and the shaft includes a seal to help reduce lubricant escape. The motor uses a plain shaft for coupling to clutches, and it does not include a holding brake, so an external locking device is required when power is removed.
