Product Description:
The MHD112D-027-NP0-LN is a three-phase servo motor produced by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. As a servo actuator, it converts drive current into precisely regulated torque for CNC machines, packaging cells, and other motion-controlled assemblies. Its keyed shaft couples directly to gears or driven machine elements, while the optical measurement system sends position signals to the drive controller for closed-loop motion. It is intended for use with compatible servo drives that monitor feedback continuously and adjust phase currents as load conditions change. That control method helps the motor maintain stable motion during acceleration, deceleration, and low-speed holding.
In continuous service, the motor can sustain 48.0 Nm of torque at standstill, so positioning axes can hold load without overheating. An enclosure rating of IP65 keeps out dust and low-pressure water jets, which allows use in exposed machine areas. Heat is removed through liquid cooling, and the housing channels carry coolant past the stator to limit temperature rise during long duty cycles. Electrical and mechanical parts operate properly when ambient air stays between 0 to 40 °C. Rotor position is reported by digital servo feedback (HSF), giving the drive precise incremental data for fast control response.
The centering pilot is machined to 130 mm, which helps align the motor accurately with a gearbox or machine plate. The square flange measures 192 mm across, matching common mounting surfaces for this frame size. The flange and pilot dimensions also help keep shaft alignment consistent when the motor is bolted to precision machine structures. Windings use the F insulation class, which allows the insulation system to handle elevated internal temperatures during normal operation. For contouring tasks, the system accuracy of ± 0.5 angular minutes supports repeatable positioning and smooth path control.
