MHD112D-027-NP3-RN
MHD Synchronous Motors
MHD112D-027-NP3-RN, Bosch Rexroth Indramat, MHD Synchronous Motors series delivers precise, high-dynamic positioning in a compact, robust package. Engineered as a Product Type: Servo Motor, it incorporates a Liquid cooling system to sustain elevated performance in demanding duty cycles. The built-in Digital servo feedback (HSF) encoder and Relative position detection guarantee accurate motion control with minimal hysteresis. Designed for industrial automation, this motor is optimized for seamless integration into advanced drive architectures.
In terms of technical specifications, the servo motor features a Continuous Torque at Standstill of 48.0 Nm, supported by a Holding Brake Torque of 70.0 Nm for secure load locking. The Holding Brake assembly ensures safe shutdowns and precise load holding under power loss. The motor’s Motor Size: 112 frame with a Flange size: 192 mm and Centering diameter: 130 mm facilitates mechanical interfacing to gearboxes and couplings. The Shaft Design: Keyed Shaft provides reliable torque transmission, while the Shaft Seal: Yes prevents ingress of contaminants. With the power interface oriented to the right via a Power Connector, installation flexibility is enhanced in cabinet layouts. The motor’s nominal winding Winding Code: 027 aligns with Rexroth drive controllers for plug-and-play commissioning. Motor length designation D represents a standard length optimized for medium to high torque density.
Integration into motion control systems is simplified by the servo’s adherence to Rexroth communication protocols and direct compatibility with IndraDrive controllers. Advanced Liquid cooling ensures continuous operation under peak loads, reducing thermal derating and extending service life. The combination of high holding torque, precise Digital servo feedback (HSF) encoder, and sealed construction enhances both safety and reliability in high-availability applications. Whether used in packaging machines, material handling, or robotic cells, the MHD112D-027-NP3-RN offers a dependable solution that minimizes downtime and maximizes throughput.

Frequently Asked Questions
What are the flange and centering dimensions?
The motor uses a 192 mm flange with 130 mm centering diameter as standard. The dimensions facilitate coupling, gearbox alignment, and mounting brackets.
How does frame “112D” classification affect shape?
The “112” indicates the motor’s outer diameter class, and “D” refers to its axial length. The classification ensures dimensional compatibility with mounting standards and adjacent hardware.
What shaft design does the RN version use?
The RN configuration employs a keyed shaft with seal to transmit torque securely. The keyed geometry ensures coupling rigidity but demands precise machining of mating parts.
How does the motor’s length impact installation?
Its D-length frame provides added rotor mass and torque volume. The extended length must be accounted for in enclosure depth and adjacent clearance planning.
How does connector orientation influence system layout?
The power connector is on the motor’s right side relative to shaft output. The lateral orientation affects cable routing and accessibility in tight cabinet environments.
