Product Description:

Bosch Rexroth Indramat manufactures the MHD112A-058-NG1-LN, a servo motor in the MHD Synchronous Motors series. The unit uses a size 112 frame with A length, giving it a compact housing for controlled axis motion in automated equipment. Its power connector exits to the left, which helps with cable routing in tighter machine layouts. A plain shaft with a shaft seal transfers torque directly to couplings or gearboxes, while the integrated digital encoder sends relative optical position data to the drive for repeatable indexing, dwell, and return moves.

The motor delivers 15.0 Nm of continuous torque at standstill, allowing it to hold process loads without external clamps. A liquid cooling jacket removes heat from the stator windings so the motor can maintain output in compact enclosures. Alignment to machine tooling is simplified by the 130 mm centering diameter, and the 192 mm flange fits standard Rexroth mounting interfaces. The housing is sealed to IP65, which helps keep dust and low-pressure water jets away from internal parts. Position feedback is supplied by digital servo feedback (HSF), supporting fast signal processing for closed-loop motion control. Additional product data includes winding code 058, a liquid-ready housing, and a maximum installation height of 1000 m above mean sea level.

For stop-and-hold conditions, an internal brake provides 22.0 Nm of static torque and engages when power is removed. The motor operates in ambient temperatures from 0 to 40 °C, and it can be stored from -20 °C to +80 °C when not in service. Insulation built to Class F supports winding temperatures up to 155 °C during operation. Overall system accuracy reaches ± 0.5 angular minutes, which supports repeatable motion in pick-and-place equipment and other positioning applications.
