Product Description:

The MDD041B-N-100-N2G-050GB1 is a permanent-magnet synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for direct integration with digital drive controllers, the unit converts three-phase electrical input into precisely regulated shaft rotation for automated pick-and-place stations, small transfer lines, and indexing tables. Its internal blocking brake supports accurate positioning and secure load holding when power is removed. The slim B-length housing also helps the motor fit installations where adjacent axes leave limited clearance.

At a nominal speed of 10,000 rpm, the rotor maintains high peripheral velocity for rapid indexing without external gearing. Continuous torque at standstill is 1.35 Nm, which provides the force needed to resist static loads during dwell periods. The integrated brake delivers 1.2 Nm of torque so the shaft stays fixed when the controller is de-energized. Dimensional alignment is provided by a 50 mm centering diameter that fits standard spigots, and all conductors exit on side B, which can simplify cable routing in right-hand mounting positions. Power and feedback connections are carried through a sealed connector, and the rotor is balanced to the standard grade to reduce vibration during extended high-speed operation.

The mechanical interface uses a plain shaft, allowing clamp couplings that minimize backlash and accommodate frequent reversals. Angular position data is supplied through resolver feedback, giving the drive continuous rotor information across the full speed range. This feedback method helps the controller maintain stable commutation during acceleration, deceleration, and standstill. Contaminant ingress is reduced by construction with a shaft seal, which helps block coolant and dust from the bearing cavity. The design omits a shaft extension on the rear face, so there is no side B shaft end. The motor belongs to size 041, and its standard housing finish supports heat transfer to ambient air while providing a durable exterior surface for routine industrial use.
