MHD115A-035-NG0-BA

The MHD115A-035-NG0-BA is a high-performance Servo Motor in the MHD Synchronous Motors series, manufactured by Bosch Rexroth Indramat. This Product Type with a Motor Size of 115 features a precision-engineered Centering diameter of 180 mm and a robust Flange size of 192 mm, ensuring compatibility with standard industrial mounts. The unit’s Motor Length (dimension A) is optimized for compact installations, while the Winding Code 035 reflects its customized electromagnetic design. Equipped with a Digital servo feedback (HSF) encoder, the motor delivers accurate position and velocity control. Notably, the model is specified Without holding brake, simplifying mechanical interfaces where external braking is preferred.

In terms of technical capabilities, the motor delivers a Continuous Torque at Standstill of 32.0 Nm under natural convection cooling and up to 48 Nm when surface cooling is applied. At standstill, it draws 31.5 A continuously in natural cooling mode and 40.4 A with surface cooling, reflecting its dynamic current handling. The motor’s theoretical Maximum Torque of 110 Nm at 4500 rpm and a Moment of Inertia of 65.0 x 10^-4 kg·m^2 provide strong acceleration and deceleration performance. A Thermal Time Constant estimated between 30 and 60 minutes ensures reliable operation under varying load cycles. The Type of Position Detection is relative, paired with the high-resolution encoder for precise motion control in automation tasks.

Operational features emphasize durability and serviceability. The Housing Cooling Type of natural convection requires no auxiliary cooling devices, reducing maintenance complexity. A Shaft Seal protects internal components from contaminants, while the Plain shaft design offers straightforward mechanical coupling. The motor’s extra protective black paint coating enhances corrosion resistance in industrial environments. Weighing 30 kg, it can be installed at altitudes up to 1000 m above sea level and operated in ambient temperatures from 0 to +40 °C, providing flexibility across manufacturing facilities.

Integration is streamlined through the Output Connector on the B-side, with Power Connection Direction oriented to side B to simplify cable routing in tight machine frames. The built-in Digital servo feedback encoder seamlessly interfaces with Rexroth Indramat drive controllers for automatic parameter matching and closed-loop control. Its standardized Flange size and connector specifications allow rapid interchangeability across automation platforms. Ideal for robotics, packaging machinery, and CNC equipment, the MHD115A-035-NG0-BA offers reliable precision and robustness in demanding industrial applications.
