Product Description:

The MDD090A-N-020-N2M-110GA1 is a servo motor manufactured by Bosch Rexroth Indramat and placed in the MDD Synchronous Motors series. It is built for integration with digital drive controllers where precise torque and speed regulation are required for positioning, packaging, or light machining axes in industrial automation. Its synchronous design supports repeatable motion on axes that must accelerate smoothly and hold commanded positions during automated cycles.

This model delivers a continuous standstill torque of 3.7 Nm, which lets the motor hold commanded position at zero speed without overheating. During regular operation it reaches a nominal speed of 2000 rpm, which is the synchronous running point used when sizing gear ratios and matching drive electronics. A blocking brake is included, and its static holding capacity is rated at 6.5 Nm, so vertical or suspended loads remain secured after power is removed. Mechanical alignment to the driven machine is aided by a centering diameter of 110 mm, allowing concentric mounting on standard flanges. All power and feedback conductors exit on side A, which can simplify cable routing when multiple motors share the same orientation.

An integrated multi-turn absolute encoder provides position data over several revolutions, while the drive reads this signal through digital servo feedback (DSF) to close the control loop without external transducers. This feedback arrangement gives the controller immediate rotor position information after startup and supports accurate positioning over repeated turns. The rotor connects to the load through a plain shaft, reducing coupling runout compared with keyed variants and supporting backlash-free clamp hubs. A shaft seal is fitted to protect internal bearings from coolant or dust ingress, and the stator frame follows motor size code 090, giving a compact cross-section that matches other units in the same family. Balancing is standard, which keeps vibration within normal limits for typical servo applications.
