MDD025B-N-100-N2G-040MA0
The MDD025B-N-100-N2G-040MA0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts commanded current into precise rotary motion for positioning, metering, or small-scale actuation tasks in automated equipment. By pairing high-speed capability with feedback that is compatible with Rexroth drive modules, it serves as a rapid and accurate drive element in assembly lines, packaging machinery, and laboratory handling devices.
Its continuous mechanical output at standstill is 0.60 Nm, indicating the torque it can hold indefinitely without exceeding thermal limits when locked. During normal operation, the rotor can reach 10000 rpm, a speed that supports fast cycle times on light inertial loads. A centering diameter of 40 mm aligns the front flange with gearboxes or mounting plates and helps keep radial runout low. Position data are returned through resolver feedback, providing analog sine-cosine signals for closed-loop control even at high acceleration. Power and sensor conductors exit on Side A, allowing cable routing toward the drive cabinet while keeping the opposite side free in tight machine layouts. The motor uses a standard housing and balancing class, so no additional counterweights or special surface coatings are required.
Electrical termination is achieved through a connector that mates with prefabricated cables and shortens installation time. The ground steel shaft uses a keyway to transmit torque into couplings or pulleys without slippage, and the design is supplied without a blocking brake, so external holding mechanisms must secure vertical axes when power is off. Because it is delivered without a shaft seal, the model suits clean, dry enclosures where no liquid ingress occurs. The standard single-ended shaft and the size-025, length-code-B envelope minimize mass moment of inertia, letting the motor deliver responsive motion in compact servo stations.
