Product Description:

The MDD041B-N-100-N2K-050GB0 is a small-frame synchronous motor engineered by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts commanded current into rapid rotary motion for pick-and-place heads, indexing tables, and other high-cycle industrial axes. Its compact 041 frame and B length code keep mass low while preserving the magnetic path needed for continuous duty. The motor is suited to tightly packed machine layouts where responsive motion and stable servo control are required in a limited installation space.

This model is mechanically balanced to the standard grade to help limit vibration at the shaft and mounting points. A centering diameter of 50 mm positions the stator accurately on mating flanges, and power and feedback cabling exits on side B, which can simplify routing when the motor is mounted deep inside a machine frame. The factory-fitted connector interface allows the wiring to be attached without hard-wiring the leads. During static operation, the motor can deliver 1.35 Nm of continuous torque, allowing it to hold a load while stopped and energized. Under rated excitation, it reaches a nominal speed of 10,000 rpm, which supports high surface velocities with small transmission ratios.

An integrated absolute encoder supplies position data, while the drive also receives resolver feedback for commutation signals. Motion is secured purely by drive torque because the unit is supplied without a blocking brake, so external holding must be provided if power-off retention is required. The output uses a plain shaft for coupling attachment, and the motor is built with a shaft seal to help keep lubricant in place and contaminants away from internal components. The shaft end follows the standard single-ended arrangement, which allows close mounting to bulkheads or gearheads without rear-side interference.
