Product Description:

The MHD112C-024-PG3-LN servo motor is manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It uses a digital servo feedback encoder that supplies absolute position data for more than 4,096 revolutions, allowing closed-loop control of rotary axes in automated machining centers and material-handling systems. This feedback arrangement lets the drive detect rotor position immediately after startup and supports accurate speed and position regulation during operation. By pairing a plain shaft with an integrated shaft seal, the unit keeps lubricants in and contaminants out while transmitting torque to couplings or gearboxes.

The motor can deliver a continuous standstill torque of 38.0 Nm, and its holding brake supplies up to 70.0 Nm to maintain position when power is removed. A protection rating of IP65 blocks dust and low-pressure water jets, allowing the housing to operate in demanding industrial areas without an added enclosure. The square flange measures 192 mm, matching common motor-mounting patterns. Power connections exit on the left through a molded power connector, which helps keep cable routing orderly. Heat is removed by liquid cooling, which supports higher continuous loads than an air-cooled design. Class F insulation withstands winding temperatures up to 155 °C, and the optical measurement method helps the feedback system maintain accuracy during temperature changes.

Positional repeatability is held within ± 0.5 angular minutes, aided by a centering diameter of 130 mm that seats the motor concentrically on machine frames. The close centering fit helps align the shaft axis with the driven load and can reduce stress on couplings during installation. Storage is allowed from -20 to +80 °C, while operation is specified for 0 to 40 °C. A maximum setup height of 1,000 m above mean sea level is permitted. Size 112 with length code C gives the motor a compact housing for its output class.
