Product Description:
The MHD115B-024-PG1-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It follows size 115 geometry with length code B and converts electrical energy into controlled rotary motion for axes that demand accurate velocity and position profiles. Its feedback is measured optically by a digital servo encoder, enabling absolute position detection over more than 4096 revolutions. A plain output shaft transmits torque directly to couplings or gear stages in packaging, printing, or material-handling machines.
At standstill, the motor delivers up to 50.0 Nm of continuous torque, allowing it to hold or slowly move heavy loads without overheating. The rectangular flange measures 192 mm, providing a standardized mounting interface that matches the associated mechanical frames, while the 180 mm centering diameter aligns the stator concentrically with the driven equipment. An enclosure rating of IP65 seals the housing against dust ingress and water jets, so cabinet-free installation on the machine frame is feasible. Heat generated in the windings is removed through liquid cooling, allowing high power density and stable performance at an operating ambient range of 0 to 40 °C. The stator follows winding code 024, ensuring electrical compatibility with matched drive controllers. The permitted installation elevation reaches 1000 m above mean sea level without derating.
A permanent-magnet holding brake is integrated and rated for 70.0 Nm, so the shaft remains fixed when power is removed during vertical or safety-critical stops. Class F insulation supports winding temperatures up to 155 °C, extending service life under thermal cycling. Closed-loop resolution is enhanced by a system accuracy of ±0.5 angular minutes, improving contour fidelity in multi-axis gantries. The motor can be stored or shipped within a temperature window of -20 to +80 °C, and a shaft seal plus side-B output connector protect internal components from coolant or lubricant splash.
