MDD041B-N-100-N2K-050MB1
The MDD041B-N-100-N2K-050MB1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts electrical commands into controlled rotation for indexing tables, pick-and-place heads, and light conveyor stations. The motor has integrated feedback, uses standard housing and rotor balancing, and mounts directly to machine frames without special adapters, providing precise speed and torque for axes that must start, stop, and reverse rapidly. Its compact format suits machine sections where installation space is limited but repeatable servo response is still required. That makes it well suited for short, repetitive moves with frequent acceleration and deceleration.
A nominal speed of 10,000 rpm permits high cycle rates in lightweight mechanisms, while the continuous torque at standstill reaches 1.35 Nm, allowing the shaft to hold position without thermal overload. An internal blocking brake adds a holding torque of 1.2 Nm, so vertical or suspended axes can remain secure when the drive is disabled. Power and feedback plugs face side B, directing cables away from the driven element, and a single industrial connector combines phase conductors with low-level signals to simplify routing. This layout helps keep wiring organized in compact machine sections and reduces interference between moving parts and cable runs.
The flange centers in a pilot recess measuring 50 mm, which helps maintain repeatable alignment during installation and service. Speed and position data are generated through resolver feedback, which tolerates electrical noise and elevated temperatures common near actuators. Output torque is transmitted through a shaft machined with a keyway, providing slip-free coupling to gears or pulleys. The front bearing area is without a shaft seal, so the motor should be installed where cutting fluids or coolant cannot reach the shaft surface. In clean, dry installations, this arrangement supports direct coupling to standard mechanical components while keeping the shaft end uncomplicated.
