Product Description:

The MDD090A-N-020-N2M-110PR0 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers. In industrial automation, it converts controlled current from the drive into precise mechanical rotation for axes that require position accuracy and repeatability. The motor is intended for servo applications where smooth speed control and accurate positioning are required during repetitive machine cycles.

This model reaches a nominal speed of 2000 rpm. At standstill, it can deliver 3.7 Nm of continuous torque, allowing steady thrust for actuators that hold static loads. The centering shoulder measures 110 mm, giving a reference surface for concentric mounting on gearboxes or flanges. A single shaft end with a keyway simplifies mechanical coupling, and no secondary shaft is provided on side B. Because the motor is built without a blocking brake, systems that must stay immobile when power is removed need an external holding method. The housing uses a standard closed frame, and electrical terminations are made with a connector. The motor has length code A, which indicates the shortest body in the 090 size group. This shorter body length helps when the motor must fit into compact machine sections or close-coupled drive trains with limited axial space.

Position data are returned through digital servo feedback from the integrated multi-turn absolute encoder, so the drive can index multiple revolutions without homing. The multi-turn encoder also allows the control system to track shaft position over successive turns during normal motion. All power and feedback plugs exit on the right side, which helps plan cable routing in multi-axis assemblies and keeps cable direction consistent where space is limited. A fitted shaft seal helps protect the bearings from coolant or dust. Size code 090 matches the motor to couplings and mounts designed for this frame. The internal balancing and housing arrangement remain standard.
