Product Description:

The MDD025C-N-100-N2K-040MB0 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed as a drive element for digital drive controllers, this compact unit converts regulated electrical energy into mechanical rotation for positioning or velocity control tasks in automated machinery and assembly lines. Its designation reveals a size-025 frame length coded C, allowing installation where rapid acceleration, limited inertia, and high spindle speed are required within tight mounting envelopes.

The motor delivers a continuous standstill torque of 0.90 Nm, enabling the axis to hold static loads without overheating when the rotor is locked. During motion it can reach a nominal shaft speed of 10000 min⁻¹, supporting fast cycle times in pick-and-place or spindle applications. Mounting accuracy is aided by a centering diameter of 40 mm, and the frame is identified by the size code 025. Power is transmitted through a shaft with a keyway, simplifying coupling to pulleys or gear sets. Standard balancing minimizes radial vibration, and the housing follows the standard variant defined for this series, so no special flanges or cooling jackets are required.

All electrical terminations are oriented toward the rear because the power and feedback connectors are located on Side B of the stator. A locking circular Connector provides the power interface, while position data is delivered by an Integrated absolute encoder complemented with Resolver feedback for coarse commutation. The unit ships without a blocking brake, so external holding methods are needed when power-off position retention is necessary, and it is supplied without a shaft seal for use in clean, cabinet-enclosed environments. The standard shaft end on the drive side simplifies integration with couplings, and the balancing class avoids additional counterweights during installation.
