Product Description:

The MHD112B-035-PP0-BN is a servo motor produced by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. As a permanently excited synchronous unit, it converts electrical energy into controlled rotary motion for positioning axes and processing spindles. The motor belongs to size 112 with length B and winding code 035. A keyed shaft transmits torque, while a power connector on side B handles the electrical connection. Digital servo feedback with an integrated optical encoder enables closed-loop control and supports accurate position monitoring.

The motor develops a continuous standstill torque of 28.0 Nm, which provides a baseline for sizing coupled loads. An enclosure rating of IP65 shields internal components from dust and low-pressure water jets, so the unit can be mounted outside sealed cabinets. A housing designed for liquid cooling removes heat directly from the stator and supports higher duty cycles than air-cooled designs. The square flange measures 192 mm, and a 130 mm centering diameter helps align the frame on machine faces. The motor is supplied without a holding brake, so external mechanical retention is required when power is removed. Insulation class F permits winding temperatures up to 155 °C, and the optical encoder reports rotor position with an accuracy of ± 0.5 angular minutes. The keyed shaft includes a shaft seal for standard hub connections.

Storage temperatures from -20 to +80 °C help protect the motor during transport and long-term storage. The permitted ambient operating range of 0 to 40 °C maintains thermal headroom during normal use. Installation is permitted up to 1000 m above MSL without derating. The feedback system provides absolute feedback for more than 4096 revolutions, so multi-turn position data is retained through power cycles. This supports applications that must recover position after a restart.
