Product Description:
Bosch Rexroth Indramat manufactures the MHD112C-035-NP3-BN as part of the MHD Synchronous Motors series. The unit is a servo motor intended for closed-loop motion tasks in automated presses, gantry axes, and transfer lines where high positional repeatability is needed. It is suited to applications that require controlled acceleration, precise stopping, and repeatable axis positioning across changing loads. By combining a keyed shaft with a factory-installed shaft seal, the motor transmits torque directly to the load while limiting lubricant leakage and the ingress of contaminants during continuous industrial operation.
The motor can deliver a continuous standstill torque of 38.0 Nm, giving drives enough margin for static holding and low-speed feed motions without thermal overload. An enclosure rating of IP65 guards the internal windings against dust and water jets, and heat is removed by liquid cooling routed through the housing so full output can be maintained in tight cabinets. Position feedback is generated by digital servo feedback (HSF) using an optical measurement method and relative position detection, enabling high-speed interpolation with the controller. The feedback chain supports a system accuracy of ± 0.5 angular minutes, which supports precise positioning during repeated motion cycles. Additional details include winding code 035, insulation class F, motor size 112, length code C, a maximum installation altitude of 1000 m above sea level, and a power connector on side B for straightforward cable routing.
A holding brake develops 70.0 Nm of static torque to secure vertical loads when the drive is disabled. Mechanical alignment is assisted by a flange that measures 192 mm square and a centering pilot of 130 mm. The motor operates in ambient temperatures from 0 to 40 °C, which suits standard indoor industrial environments. It can be stored between –20 °C and +80 °C without degradation, allowing the unit to remain idle for extended periods before installation or between service intervals.
