Product Description:
The MHD112B-035-PG1-AN is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. Designed for closed-loop automation, the unit combines a liquid-cooled housing with an integrated digital feedback encoder, allowing precise absolute position reporting over more than 4096 revolutions. Its plain shaft and included shaft seal support use in environments where oil splash or airborne debris could otherwise migrate into the bearing set.
The motor sustains a standstill torque of 28.0 Nm, giving machine axes steady holding capacity during low-speed machining or dwell cycles. Thermal energy created at that load is removed through liquid cooling, a method that reduces frame temperature without forced air inside the cabinet. The motor is rated IP65, which helps protect internal components from dust and water jets. The rated ambient temperature range is 0 to 40 °C, and storage is permitted from -20 to +80 °C. The mounting interface uses a 192 mm square flange, and power is routed to side A through an output connector. Optical measurement inside the feedback unit, combined with Class F insulation, supports continuous duty in servo applications.
An integral brake delivers 22.0 Nm of holding torque for vertical axes when power is removed. Alignment during installation is aided by a 130 mm centering diameter that fits standard locating pilots. Position repeatability benefits from a feedback system accuracy of ± 0.5 angular minutes, enabling fine contour tracking in multi-axis cells. The motor can be installed up to 1000 m above MSL without derating, and its length code B with size 112 stator laminations keeps inertia moderate while accommodating the required copper volume.
