Product Description:

The MHD112C-058-PG0-AN belongs to the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a three-phase servo motor designed to deliver precise rotary motion for positioning axes, gantries, and transfer stations in industrial automation. The model combines a 112 frame size with motor length C to fit medium-to-large machinery where continuous torque density and closed-loop feedback are required. This arrangement suits axes that need repeatable speed control and accurate position response during frequent starts, stops, and load changes.

The motor mounts to machinery through a centering pilot of 130 mm and a square flange that measures 192 mm on each side, providing rigid alignment with the driven load. It can generate 38.0 Nm of continuous torque at standstill, which helps the axis remain stable during dwell periods while the drive maintains current to the windings. A plain shaft transmits torque without keyways or serrations, which is useful where couplings clamp directly on the journal. Because the power leads exit toward side A through an output connector, cable routing can follow the motor housing and stay clear of moving parts. That connector position can also reduce cable interference around adjacent machine structures. The shaft includes a seal to help limit lubricant escape and contaminant ingress, and the unit is delivered without a holding brake.

Thermal regulation is achieved through an internal jacket that supports liquid cooling, allowing higher duty cycles than comparable air-cooled motor versions. Rotor position is monitored by digital servo feedback from an integrated absolute encoder, and the stator windings use winding code 058 so the electrical characteristics align with compatible Rexroth drive controllers. The encoder provides absolute position detection over 4096 revolutions, so the control system can retain multi-turn position information after a power cycle. Liquid coolant removes heat from the motor body without relying on a fan mounted on the housing. This feedback arrangement supports accurate restart behavior on axes where repeated homing would interrupt machine operation.
