Product Description:

The MHD112B-058-NG1-BN servo motor is produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It serves as an electromechanical actuator that delivers controlled rotary motion to automated tooling, conveyors, and multi-axis positioners in industrial plants, where precise feedback and fast torque build-up are essential. Its synchronous design allows the drive to regulate speed, torque, and position with stable response during repeated motion cycles. This makes it suitable for axes that must accelerate quickly and stop accurately under varying load conditions.

The motor has frame size 112 with length code B and a centering diameter of 130 mm at the mounting surface. A flange diameter of 192 mm supports rigid fixation to machine structures, and a plain shaft with a shaft seal helps block particle ingress at the output end. Continuous torque at standstill reaches 28.0 Nm, and heat is removed through liquid cooling to support sustained operation. The enclosure has an IP65 rating to resist dust and low-pressure water exposure, and the power connector exits on side B through an output connector. Digital servo feedback derived optically supplies relative position data to the drive under winding code 058.

A spring-applied brake delivers 22.0 Nm of holding torque to secure vertical loads when power is removed. System feedback resolution provides positioning accuracy of ± 0.5 angular minutes, and insulation class F supports operation in ambient temperatures from 0 to 40 °C. During storage or shipment, the motor tolerates temperatures from -20 to +80 °C, and installation is permitted up to 1000 m above sea level without derating. The sealed shaft and enclosed housing help protect internal parts from contamination, while the cooling circuit stabilizes winding temperature during repeated starts, stops, and holding periods.
