Product Description:

The MDD041A-N-100-N2G-050FA1 is a synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into tightly regulated rotation for positioning and velocity loops in automated equipment. Its size-041 frame and short A-length body fit compact packaging lines, small gantries, and other machines that need high spindle speed without consuming cabinet space. Standard rotor balancing and a standard housing let the unit mount directly to light mechanical frames while keeping vibration and thermal rise within accepted limits.

At a nominal speed of 10000 min⁻¹, the rotor supports rapid duty cycles. Continuous stall torque is 0.64 Nm, defining the load the axis can hold motionless while energized. The integrated blocking brake applies 1.2 Nm of static torque to secure the shaft when power is removed. A centering diameter of 50 mm guides accurate flange alignment, and all leads exit on Side A so cable runs can follow a single routing plane. The cast-aluminum housing cools by natural convection, and the rotor is balanced to the standard grade to limit residual vibration during high-speed service.

Electrical power and feedback lines mate through a single Connector that permits quick replacement without rewiring. Position data is delivered by Resolver feedback, giving absolute angle information even at maximum speed. Mechanical output is via a Plain shaft in the standard single-ended form, eliminating any side B projection. Because the motor ships Without shaft seal, it should be installed where liquid ingress is controlled or an external seal is provided. The compact A-length body keeps inertia low, supporting lightweight pick-and-place axes and other applications that benefit from fast acceleration.
