Product Description:

The MHD112C-058-PG3-BN is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. It is designed for closed-loop industrial motion where precise acceleration, speed, and position must be coordinated with drive electronics and machine controllers. This makes it suitable for automated axes that require stable torque delivery, accurate feedback, and repeatable motion during continuous production.

The motor delivers a continuous standstill torque of 38.0 Nm, so static loads can be held without overheating. An enclosure rated at IP65 helps keep dust and water jets away from internal components. Rotor movement is monitored by digital servo feedback with an integrated encoder, which provides incremental and commutation data through an optical measurement method. Heat is removed through liquid cooling, and coolant passages in the housing help maintain thermal stability across an ambient range of 0 to 40 °C. The motor uses a 130 mm centering diameter, a 192 mm square flange, and a plain shaft with a shaft seal. Power is routed through a connector on side B, which can help separate motor power leads from feedback cabling. The C-length housing, frame size 112, and winding code 058 are intended for installation up to 1000 m above mean sea level, and storage temperatures can range from -20 °C to 80 °C without damaging the insulation.

A holding brake rated at 70.0 Nm locks the shaft during power-off sequences, which is useful on vertical axes or applications that must remain stationary at rest. Class F insulation permits winding temperatures up to 155 °C. Closed-loop positioning accuracy reaches ± 0.5 angular minutes, and the feedback system supports absolute multi-turn tracking of more than 4096 revolutions, so rotor angle remains available after a restart. This feedback arrangement supports positioning tasks that depend on repeatable reference data after power returns.
