MDD025C-N-100-N2G-040MA1
The MDD025C-N-100-N2G-040MA1 is a synchronous servomotor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts commanded electrical input into controlled mechanical rotation for positioning and velocity tasks in industrial automation cells and packaging lines. The compact design suits lighter gantry axes where high speed and low inertia are important. It can also be used in small transfer units, feeders, and indexing mechanisms that need quick response without the bulk of a larger motor frame. This operating profile makes it suitable for compact motion systems that need accurate starts, stops, and repeated direction changes.
In operation, the motor delivers 0.90 Nm of continuous torque at standstill, which is the available holding torque while the shaft remains energized and stationary. When rapid cycling is required, its nominal speed of 10000 rpm supports high-throughput spindle or indexing axes with short move times. A built-in blocking brake supplies 1.0 Nm of static torque to hold the shaft when power is removed, which is useful on axes that must stay in place during a stop. Rotor position is reported through resolver feedback, allowing sinusoidal commutation and stable speed regulation under digital drive control. The centering flange measures 40 mm in diameter and provides the alignment interface for gearboxes or mounting plates.
Power and feedback lines terminate on a connector located on Side A, allowing the cable bundle to run parallel to the machine frame and helping in tight layouts. The motor is supplied without a shaft seal, so the machine interface should be protected from coolant or heavy splash when needed. Torque is transmitted through a keyway shaft, and the standard shaft end on the drive side avoids the need for a rear shaft extension. Standard dynamic balancing helps keep vibration low at high rotational speed. The C length code indicates the overall stack height within the 025 frame size.
