MHD112D-027-NG0-BN
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD112D-027-NG0-BN is part of the MHD Synchronous Motors series from Bosch Rexroth Indramat and delivers precise, high-performance motion control. This Servo Motor features a Motor Size 112 frame and a Motor Length D housing optimized for compact installations. With a Centering diameter of 130 mm and a robust Flange size of 192 mm, the unit mounts securely in position-sensitive applications. The motor offers a Continuous Torque at Standstill of 48.0 Nm, ensuring stable holding torque when stationary.
Advanced design elements include liquid-cooled operation via the Housing Cooling Type Liquid cooling system, preserving performance under sustained load. Position feedback is handled through a high-resolution Digital servo feedback (HSF) Encoder Type, while Type of Position Detection Relative supports absolute and incremental motion strategies. The motor is configured without compromise: a Plain shaft design with integrated Shaft Seal Yes guarantees reliable operation in challenging environments. Electrical connections are routed to side B through a secure Output Connector interface, reducing cable routing complexity.
Engineered for seamless integration, the MHD112D-027-NG0-BN carries a Winding Code 027 tailored for dynamic response and thermal stability. The absence of a Holding Brake Without holding brake streamlines the rotor assembly and minimizes inertia. Whether paired with advanced drive systems or legacy controllers, this servo motor delivers consistent, repeatable performance in automated manufacturing, robotics, and precision indexing applications.

Frequently Asked Questions
What determines the continuous torque at standstill?
The continuous torque at standstill is determined by the motor’s thermal limits and winding design. The specification ensures optimal torque delivery without exceeding allowable temperature rise.
Why is the rated speed limited to 3000 rpm?
The rated speed of 3000 rpm is defined by mechanical balancing and bearing constraints. The limit prevents excessive vibration and maintains precision in servo control.
How does the voltage constant affect motor control?
The voltage constant defines the relationship between speed and back EMF generation. The parameter ensures predictable voltage behavior, simplifying servo amplifier tuning and feedback integration.
What is the purpose of the IP65 protection rating?
The IP65 protection rating safeguards internal components from dust and low-pressure water jets. The feature allows reliable operation in industrial environments with exposure to debris or moisture.
Why is the motor’s torque constant important for performance?
The torque constant specifies the torque produced per ampere of current. The parameter ensures efficient torque generation and stable performance under variable load conditions.
