Product Description:

The MDD025C-N-100-N2K-040MR0 is a brushless synchronous motor produced by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts electrical energy into rotary motion for axes that require high acceleration and fast positioning in automated machinery. Its mechanical interface and electrical feedback are coordinated with Indramat drive modules to support closed-loop operation in multi-axis equipment. This makes the motor suitable for compact handling systems, indexing units, and other applications where repeatable motion and a small installation envelope are important.

This C-length unit develops a continuous standstill torque of 0.90 Nm, allowing light load holding without overheating. When supplied with rated current from the controller, it can reach a base speed of 10000 rpm, supporting fast traverse cycles. A centering diameter of 40 mm aligns the flange with machine frames, while the power and feedback plugs exit on the right side to reduce cable loops in compact cabinets. The signal and power interface uses a single connector, which keeps wiring straightforward. Position data are delivered by an integrated absolute encoder, so the axis can retain position information after power loss.

For dynamic servo loops, the drive also reads analog signals from resolver feedback, which supports stable commutation during operation. Torque is transferred through a keyed shaft, and the keyway helps secure pulleys or gearboxes during rapid reversals. The frame size code 025 keeps the external diameter and mass low, making the motor suitable for tight spaces and low-inertia axes. The motor has a standard enclosure, no blocking brake, no shaft seal, a standard drive-side shaft end, and no second shaft on side B.
