The Bosch Rexroth Indramat MDD112C-N-020-N2M-180PB2 servo motor from the MDD Synchronous Motors series delivers robust and precise motion control for demanding industrial automation applications. This motor integrates a digital servo feedback system along with an integrated multiturn absolute encoder to provide continuous, high-resolution position updating of the output shaft. Rated for a nominal speed of 2000 min⁻¹, it achieves a continuous torque at standstill of 28.0 Nm and a maximum torque of 97.3 Nm at peak performance. Equipped with a blocking brake offering holding brake torque of 40.0 Nm, the MDD112C-N-020-N2M-180PB2 ensures secure motor locking under emergency or power-off conditions. Its keyway shaft and shaft seal enhance mechanical stability and environmental protection in the most challenging operating environments.
The motor’s mechanical and electrical specifications have been optimized for integration with digital drive controllers. It uses a standard housing with a centring diameter of 180 mm and a motor size code of 112C, reflecting its modular design. The winding shows an inductance of 5 mH and the rotor thermal time constant is 100 minutes for controlled thermal management. This motor is balanced to balance class N per DIN VDE 0530 section 14, minimizing vibration for smooth operation. All electrical connections are made via a side B connector rated for digital servo feedback (DSF), and the unit features a standard shaft end without side B extension to simplify coupling design.
Operational performance is assured through lifetime grease-lubricated bearings that guarantee long life and uninterrupted operation in ambient temperatures from 0 to +40°C up to a permissible altitude of 1000 m above sea level. At nominal speed the motor draws a peak current of 110.5 A, while at standstill it requires 29.7 A to maintain continuous torque. Weighing 48 kg, the unit demands careful handling and a robust support structure during commissioning. Its robust design, including a shaft seal and a blocking brake, ensures fault-tolerant performance in applications ranging from chemical processing units to high-speed printing machines.
System integration is facilitated by its classification as a motor for digital drive controllers, enabling seamless compatibility with Bosch Rexroth Indramat drive electronics. Mounting in any orientation is supported, provided recommended bolt sizes are used for tightening. The combination of advanced feedback, secure braking, and standardized connection interfaces makes the MDD112C-N-020-N2M-180PB2 ideal for robotics, handling machines, CNC axes, and other precision automation installations where reliability, accuracy, and serviceability are paramount.
