Product Description:

The MDD090C-N-020-N2M-110PL2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It connects to digital drive controllers to convert electrical commands into controlled rotary motion for positioning and speed regulation in automated machinery. The unit follows the 090 frame class with a C-length stator and a standard housing that fits directly onto compatible machine flanges. This arrangement supports precise axis movement in machines that need repeatable starts, stops, and speed changes during automatic operation.

At standstill, the motor delivers 10.4 Nm of continuous torque, enabling position holding and low-speed feeding without thermal overload. When driven by the specified commutation frequency, it reaches a nominal speed of 2000 rpm, giving predictable velocity control across normal operating ranges. The centering spigot diameter is 110 mm, which helps align the motor accurately with the machine frame during installation. Power and feedback leads exit on the left side through a sealed connector, reducing cable bend and supporting cleaner routing in confined spaces. Rotor position is resolved by an integrated multi-turn absolute encoder, allowing the controller to recognize position immediately after startup.

For static holding or vertical loads, the integrated blocking brake supplies 11.0 Nm of torque and releases when the drive energizes the coil. Command and diagnostic signals travel through digital servo feedback (DSF), so position and temperature data reach the controller in real time for closed-loop control. The shaft has a shaft seal that limits lubricant escape and helps keep contaminants away from the bearings. Mechanical power is transmitted through a keyway, which supports secure coupling and helps resist slip under cyclic torque. Standard dynamic balancing supports smooth rotation across the speed range and helps limit vibration in connected machine elements.
