Product Description:

The MDD041A-N-100-N2G-050PB1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive commands into precise high-speed rotation suited to assembly stations, pick-and-place axes, and similar repetitive automation duties. Its combination of high speed and an integrated blocking brake supports rapid cycles while still holding the axis in place between moves. In automated equipment, the motor supports quick acceleration and accurate stopping on axes that repeat the same motion profile throughout a production cycle.

At its rated operating point, the rotor can reach 10,000 rpm, giving the axis the high velocity needed by lightweight tooling. At standstill with current applied, it can sustain 0.64 Nm of continuous torque before thermal limits are reached. The blocking brake adds a holding torque of 1.2 Nm, so the load can remain fixed after power removal. Alignment of the housing to a gearbox or flange is simplified by a 50 mm centering diameter. Power and feedback leads exit on side B, which keeps the front face clear for tight mounting inside multi-axis assemblies. This arrangement also helps simplify cable routing when several axes are installed close together in a compact machine section.

The motor uses a connector for the electrical connection, which supports quick cable attachment. A shaft seal is included to limit coolant splash and dust ingress, and the output end uses a keyway shaft profile for conventional pulleys or couplings. The motor uses length code A, which indicates the shortest housing in this frame size and helps conserve installation space. Feedback is supplied by resolver feedback, which provides robust rotor position signals for commutation and stable speed control. The compact housing can be useful where available mounting depth is limited by guards, transfer mechanisms, or densely packed axis layouts.
