Product Description:

The MDD041A-N-100-N2K-050MB1 is a brushless synchronous servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers precise torque and speed for automated pick-and-place modules, light conveying sections, and compact indexing stations. Frame code 041, the A length, and a standard housing keep external dimensions minimal, while connector-style power and feedback terminations simplify cabinet layout. Standard rotor balancing reduces vibration at elevated operating speeds so adjacent sensors and mechanical components remain stable during long production shifts.

This motor supplies a continuous standstill torque of 0.64 Nm, allowing the drive to hold light loads without thermal overload when airflow is limited. Its nominal mechanical speed reaches 10000 rpm, supporting high-rate positioning cycles when paired with a suitable inverter. Power and feedback leads are routed to the rear because the electrical interface is mounted on side B. Accurate centering against gearbox or coupling hardware is provided by a 50 mm pilot diameter, which helps prevent radial runout at the maximum rated speed. A standard shaft end is supplied on the drive side only, which avoids unnecessary overhang mass on the non-drive end.

For static holding or emergency stops, an integrated blocking brake develops 1.2 Nm of torque and is released when the controller energizes it. Position feedback during motion uses resolver feedback, and an integrated absolute encoder provides multi-turn position data at power-up so homing routines are not required. The output shaft uses a keyway profile so torque can be transmitted without slip during rapid reversals. The housing is supplied without a shaft seal, so the coupling area should remain clean during operation.
