Product Description:

The MHD115A-035-PP1-RA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for closed-loop industrial automation axes where rapid positioning and precise velocity regulation are required. By integrating an absolute position encoder and an electromechanical holding brake, the unit can both move and securely hold loads in packaging, material-handling, or machining cells.

This motor delivers a continuous standstill torque of 32.0 Nm, allowing it to maintain rated load without overheating when the shaft is stationary. A sealing system rated at IP65 protects the stator windings from dust ingress and low-pressure water jets so the motor can be mounted directly on process equipment. The integrated brake supplies 70.0 Nm of static torque, letting vertical axes remain fixed when power is removed. Rotor position is reported through digital servo feedback that uses an optical measuring method to provide absolute data for more than 4096 revolutions. This feedback contributes to a system precision of ±0.5 angular minutes, which supports fine contouring or indexing tasks. Additional mechanical data include a 192 mm square mounting flange, a 180 mm centering diameter, and size code 115 with length designation A, all of which match the motor to classic DIN flange interfaces. Class F insulation sustains winding temperatures up to 155 °C during continuous duty.

For proper operation, the machine enclosure must remain within 0 to 40 °C, and storage can occur from −20 °C up to 80 °C without affecting magnet strength. A keyed shaft transfers torque into gearboxes or timing pulleys, while a shaft seal prevents lubricant migration toward the bearings. Power exits the housing through a right-facing power connector, simplifying cable routing in cabinets below the motor. Heat produced by copper losses is removed only through natural convection, so the installation height should stay under 1000 m above mean sea level to maintain the specified thermal reserve. The winding code 035 indicates the electrical parameters required by the drive controller.
