Product Description:

Bosch Rexroth Indramat builds the MDD090C-N-020-N2M-130PR0 as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies rotational power to axes that require closed-loop speed and position regulation in industrial automation lines. When paired with a compatible controller, it converts commanded current into controlled torque and speed for indexing tables, feed axes, and transfer systems. The synchronous design supports stable motion response during repeated start-stop cycles.

The motor delivers a continuous standstill torque of 10.4 Nm, giving drive controllers a predictable load reference for low-speed holding and indexing tasks. Its rated speed is 2000 rpm, which is the nominal operating speed under rated voltage. A centering diameter of 130 mm simplifies concentric alignment to gearboxes or mounting flanges, and the rotor-shaft assembly is balanced to a standard grade to reduce vibration during operation. Power and feedback leads exit on the right side, so adjacent machine surfaces should leave clearance on that face. A single connector carries both motor phase conductors and encoder lines, which keeps cable routing compact. This arrangement reduces the number of separate cable entry points at the motor housing and can simplify routing in compact machine sections.

The shaft uses a keyway and is provided only on the drive side, so couplings can seat positively without an auxiliary extension on side B. Motion is monitored by an integrated multi-turn absolute encoder, which transmits angle and revolution data through digital servo feedback (DSF) and allows position information to remain available after power cycling. Absolute feedback supports closed-loop operation without a homing move after every restart, which is useful on axes that cannot easily return to a reference mark. The motor is supplied without a blocking brake, so any axis that must remain fixed during shutdown needs external holding force. The motor has a standard housing and a shaft seal to help keep dust or coolant from entering the interior.
