MDD025A-N-100-N2G-040PL1
The MDD025A-N-100-N2G-040PL1 synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive output current into mechanical rotation for compact pick-and-place heads, labeling stations, and other light-duty axes that demand rapid acceleration and precise velocity control within automated lines. Its mechanical envelope follows the series layout so that multiple frame variants use the same mounting face and electrical interface across modular machines.
The motor body interfaces with the machine frame through a centering diameter of 40 mm, which aligns the stator face concentrically with the driven load to help keep runout low. All power and feedback conductors exit on the left side, and the factory-installed connector allows straightforward cable mating. Under continuous stall conditions, the electromagnetic system delivers 0.33 Nm of torque, which supports static holding against light loads while the controller maintains position. When commanded to full frequency, the rotor reaches a nominal speed of 10000 rpm, allowing short cycle times on high-speed positioning axes without exceeding thermal limits.
During power-off or emergency-stop events, a blocking brake inside the housing produces 1.0 Nm of holding torque, helping prevent back-driving of vertical or torsion-loaded mechanisms. Position data is returned to the drive through resolver feedback, enabling analog sinusoidal sensing that remains accurate at high temperatures and high speed. The single-ended shaft uses a keyway so pulleys or couplings can transmit torque without slip, and a shaft seal protects the front bearing against coolant splash. With frame size 025 and standard balancing, the rotor runs with low vibration, while length code A keeps overall mass and moment of inertia low for responsive starts and stops.
