Product Description:

The MDD090C-N-020-N2M-130GR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed for integration with digital drive controllers, the unit converts commanded current into controlled rotational motion in automated machinery, positioning tables, and packaging axes. The standardized housing and balancing allow it to mount directly onto precision frames while supporting accurate operation in multi-axis assemblies. With a motor size code of 090 and a C-length stator, it fits mid-range power cells without exceeding cabinet depth requirements.

At standstill, the motor can deliver a continuous torque of 10.4 Nm, giving a baseline for gear ratio selection when static holding force is important. Under rated field excitation, the rotor reaches a nominal speed of 2000 rpm, which aligns with speed classes commonly used by Indramat supply modules for moderate-speed conveyor drives. Position data is generated by an integrated multiturn absolute encoder and returned through the drive control bus. This device preserves shaft angle across power cycles and eliminates homing routines. Real-time velocity and position loops use Digital servo feedback (DSF), minimizing control lag in applications that demand high stiffness. Mechanical centering relies on a 130 mm pilot diameter, and the electrical and feedback connections are positioned on the right side to streamline cable routing.

The motor is supplied without a blocking brake, so any vertical axis must use external holding measures when power is removed. A plain shaft mates directly with zero-backlash couplings, while the plug-in connector interface keeps installation straightforward. Bearing lubricant is protected from contaminants by construction with a shaft seal, which helps keep debris away from internal mechanical parts.
