Description
The Rexroth MHD112D-027-PG3-AN is a high-performance synchronous servo motor designed by Bosch Rexroth (Indramat). It is engineered for demanding industrial applications requiring high precision, rapid acceleration, and exceptional reliability in motion control.
Product Introduction
The MHD112D-027-PG3-AN belongs to the MHD series of permanent magnet motors. These motors are recognized for their high power-to-weight ratio and maintenance-free operation due to their brushless design. The Rexroth Servo Motor is equipped with an integrated encoder system that provides real-time position and speed feedback to the drive controller, ensuring closed-loop accuracy in complex automated sequences.

Product Usage Instructions
- Installation: Ensure the motor is mounted on a flat, thermally conductive surface to facilitate natural convection cooling. Use the standard 192mm flange for alignment with the gearbox or machine interface.
- Cabling: Use original Rexroth power and encoder cables. The power connector and encoder connector are circular and must be tightened to the specified torque to maintain the IP65 rating.
- Drive Compatibility: This motor is designed to work with Indradrive or DIAX04/ECODRIVE controllers. Ensure the motor parameters are correctly loaded via the drive software (e.g., DriveTop or IndraWorks).
- Brake Operation: The integrated 70 Nm holding brake is for static holding only. Do not use it for dynamic braking unless in emergency stop conditions, as this will lead to premature wear.
Application Fields
- Machine Tools: High-speed CNC machining and milling.
- Packaging Machinery: Precise synchronization of conveyor belts and bottling lines.
- Printing Industry: Accurate tension control and paper feeding.
- Automotive: Robotic assembly lines and heavy-duty positioning.
Recommended Similar Models
For users looking for different torque ratings or frame sizes within the Rexroth MHD family, the following models are recommended:
- MHD093C-035-PG1-AN: A smaller frame size (093) for compact high-speed tasks.
- MHD112C-058-PG1-AN: A shorter version of the 112 frame with a different winding profile.
- MHD115B-024-PG1-BN: A larger frame size for applications requiring higher peak torque.
- MKD112D-027-GG0-AN: A similar frame size from the MKD series for different drive requirements.
- MHD112D-027-NG1-AN: A variant of the same frame size without the holding brake option.
