MDD025A-N-100-N2G-040MF1
The MDD025A-N-100-N2G-040MF1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into precise rotary motion on light-duty axes, indexing tables, or compact pick-and-place modules. The model follows the series standard housing profile, carries a standard dynamic balancing grade, and includes an internal blocking brake so it can hold position when power is removed. This layout suits compact automation equipment where repeatable motion and secure standstill holding are both required.
The centering diameter is 40 mm, giving a rigid reference surface that improves alignment between the stator and the mounting flange. At standstill, the motor supplies a continuous torque of 0.33 Nm, which is useful for light-duty positioning tasks and steady holding under normal thermal conditions. During operation, the rotor can reach 10000 rpm, allowing short cycle times in fast-moving stations. When the axis is idle, a blocking brake rated at 1.0 Nm helps secure the load against drift. Mechanical power leaves the unit through a keyway shaft, which supports positive torque transfer to pulleys or couplings and helps reduce slip under changing load.
Feedback is supplied by resolver feedback, permitting position sensing over the electrical cycle without battery-backed memory. Cabling exits on the right side, and the motor is delivered with a connecting cable with a coupling unit so the electrical interface is ready for direct installation. The frame corresponds to size 025, and the A length code keeps the body short for rapid start-stop motion. Because there is no shaft seal, the motor is better suited to clean installation areas that are protected from direct fluid exposure. The shaft is provided only on side A, which helps keep the rear of the motor compact for tight machine layouts.
