Product Description:
The MHD112D-027-NP3-LN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a rotary actuator, it delivers closed-loop motion for industrial axes that need precise velocity and position profiles. Relative position feedback, a keyed output shaft, and a sealed housing allow the motor to be installed on packaging lines, material-handling gantries, or machine-tool spindles where contamination and washdown conditions are common. Its synchronous design supports responsive control during repeated starts, stops, and position changes.
The motor sustains 48.0 Nm of continuous standstill torque, and excess heat is removed through liquid cooling integrated into the housing jacket. A protection rating of IP65 helps keep dust and low-pressure water jets away from internal components. The square mounting flange measures 192 mm, providing a standard interface for gearboxes or direct-drive couplings. Rotor angle is reported by digital servo feedback (HSF), which sends position data to the drive controller for smooth interpolation and stable loop response.
For static holding or emergency stops, the built-in brake delivers 70.0 Nm of torque, allowing vertical axes to remain in place when power is removed. Precise alignment to connected machinery is aided by a centering diameter of 130 mm, and the motor maintains rated output within an ambient range of 0 to 40 °C. System accuracy reaches ± 0.5 angular minutes, which supports fine indexing tasks without an external encoder. Class F insulation allows a 155 °C winding limit, and a shaft seal helps limit lubricant migration. Optical rotor-position measurement is used, power connectors are on the left side, the maximum installation height is 1000 m above mean sea level, storage is permitted from −20 °C to 80 °C, and winding code 027 matches the drive’s voltage and current ratings.
