Product Description:

The MDD025C-N-100-N2G-040GD0 is a synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical power into mechanical rotation for light-duty axes in automated assembly, test, or pick-and-place stations. Integrated resolver feedback streams real-time position data to the drive so that speed and angle can be closed-loop regulated. The 025 frame designation and C-length body create a compact footprint that simplifies installation in tight machine compartments where high rotor speed is still required.

At standstill the motor produces 0.90 Nm of continuous torque, giving the servo stage enough holding force for indexing or dwell periods without overheating. During motion it can reach a nominal velocity of 10000 min⁻¹, allowing rapid cycle times when paired with a matched inverter. Mechanical centering on a 40 mm pilot diameter ensures concentric alignment with gearheads or bell housings. Power and feedback leads exit on Side B of the housing and are routed through a connecting cable with a coupling unit, reducing enclosure depth at the shaft end. Position data is generated by Resolver feedback, a sensor technology tolerant of electrical noise and high rotational speed. Output torque is transferred through a Plain shaft, eliminating keyway stress points and enabling smooth coupling to clamped hubs.

Standard dynamic balancing minimizes residual vibration, and the motor housing follows the series’ standard cooling surface design. The length code C defines the active stack height that determines the continuous power rating without altering the 025 frame diameter. For holding applications the unit is supplied without a blocking brake, so external locking or static drive torque must maintain load position when power is removed. Contamination ingress is limited by construction with a shaft seal, and the shaft end is provided only on the drive side, preserving a short overall length on side B.
