MDD041B-N-100-N2G-050PB1
The MDD041B-N-100-N2G-050PB1 servo motor comes from the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. As a motor for digital drive controllers, it converts electrical power from the drive into mechanical rotation so that compact pick-and-place stations, small indexing tables, and other automated axes can reach repeatable target positions at high speed. Its resolver-based position loop makes the unit appropriate for applications that depend on continuous feedback to maintain tight velocity and position tolerances during frequent starts, stops, and short positioning moves. This makes it suitable for motion tasks that require smooth response and stable tracking through repeated operating cycles.
At standstill, the motor provides a continuous torque of 1.35 Nm, which is the sustained load it can hold during precision dwell periods. A maximum operating speed of 10,000 rpm allows rapid traverse in short-stroke mechanisms without gearing. The centering diameter measures 50 mm, matching standard flanges for accurate alignment to gearboxes or machine frames. All power and feedback conductors exit on Side B, a layout that keeps the cable bundle away from moving parts when the shaft faces the process. Position information is generated through resolver feedback, enabling sinusoidal commutation and good resistance to electrical noise in industrial environments.
The blocked-rotor brake supplies 1.2 Nm of holding torque so loads remain stationary during power-off conditions or emergency stops. Sealing elements include a shaft seal that helps limit lubricant loss and particulate ingress at the output journal. A keyway shaft type simplifies coupling to timing pulleys or precision hubs, while standard balancing helps keep residual vibration within common ISO limits for low-mass rotors. The housing uses the series' standard enclosure, and the motor size is coded 041 with a compact B length for installations with limited depth. A molded connector handles both power and signal conductors, and the shaft is provided only on the drive side to avoid side-B overhang loads in narrow mechanical packages. This arrangement also helps keep the rear end compact in tightly spaced machinery.
