Product Description:

Bosch Rexroth Indramat supplies the MDD025C-N-100-N2G-040FE0 synchronous motor within the MDD Synchronous Motors series. Designed for closed-loop operation on digital drive controllers, the unit provides high-speed rotary actuation for pick-and-place heads, small spindles, and indexing mechanisms in automated machinery.

At the heart of its performance envelope is a continuous standstill torque of 0.90 Nm, allowing the 025-frame motor to hold modest loads without additional gearing. When excited with rated current, the rotor attains a nominal velocity of 10000 min⁻¹, so high-cycle positioning can be executed with minimal dwell. The rotor is manufactured with standard balancing, keeping residual vibration low at the specified speed range. A centering pilot of 40 mm simplifies concentric alignment to gearboxes or flange plates, and the plain shaft eliminates keys that could introduce micro-play under reversing duty. The standard housing supports natural convection, and the C-length active core delivers the necessary magnetic path length without increasing diameter.

Electrical integration is straightforward because power and sensor conductors exit on the Left of the stator through a connecting cable with coupling unit, keeping the motor profile clear on the opposite side for mounting hardware. Position data is delivered by resolver feedback, enabling the drive to interpolate absolute angle even during rapid reversal. For applications where dynamic braking torque is supplied by the inverter, the motor is shipped without a blocking brake, and the shaft is built without a shaft seal to avoid drag that could heat the small rotor. The single-ended shaft configuration, with no side-B extension, reduces overhung mass, while the C length code and the motor-for-digital-drive-controllers product type together make the unit suitable for compact multi-axis assemblies that depend on low inertia and consistent thermal behavior.
