MDD041B-N-100-N2G-050MB0
The MDD041B-N-100-N2G-050MB0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts command signals into controlled rotary motion for industrial positioning axes. Its design supports high-speed cycles and tight torque regulation required in pick-and-place units and light-duty tooling spindles. It is intended for digitally controlled motion systems where repeatable starts, stops, and speed changes are required within a limited installation space. This layout suits compact machine sections where the motor must deliver precise motion without adding unnecessary bulk to the axis.
A nominal operating speed of 10,000 rpm enables fast indexing, while the continuous standstill torque of 1.35 Nm allows the axis to hold load without overheating. The rotor is balanced to a standard grade to reduce residual vibration, and the housing uses the standard enclosure style for uniform mounting surfaces. Accurate centering is provided by a 50 mm pilot diameter, which helps align the motor with couplings or gearboxes. Power and feedback connections exit on side B, which can simplify cable routing and reduce bend stress near the motor face. That combination fits light axes that need quick acceleration and stable alignment during repeated indexing cycles.
Electrical integration is simplified because the unit uses resolver feedback for rotor position reporting through a single multifunction cable terminated by a connector. For applications that use external locking devices, the motor is supplied without a blocking brake, which eliminates added drag during rapid acceleration. The shaft is configured without a shaft seal, making it better suited to clean, dry environments where low friction is preferred. Torque is transmitted through a keyway, and the compact size code 041 with length code B helps keep installation depth low behind the machine frame. The single-cable arrangement also keeps the connection area compact at the motor body.
