Product Description:

The MDD065B-N-040-N2L-095PL1 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Intended for use with digital drive controllers, the unit converts drive current into mechanical motion so closed-loop axes can maintain precise position and speed in automated machinery. Its B-length housing, standard balancing, and single-ended shaft make it suitable for compact installations where accurate feedback and repeatable torque delivery are required.

A centering shoulder of 95 mm aligns the motor to the machine frame, helping minimize runout during high-speed rotation. At standstill, it can provide 1.5 Nm of continuous torque, which is the thermal limit for uninterrupted holding or low-speed indexing. Under rated electrical excitation, the rotor reaches 4000 rpm, allowing rapid cycle times on light to medium-load axes. Power and feedback conductors exit on the left side through a sealed connector, which can simplify cable routing in machines with a consistent layout. The shaft is machined with a keyway, giving positive mechanical engagement with pulleys or couplings and helping prevent slip during acceleration or braking.

Dynamic stopping capability is handled by an internal holding device that applies 3.0 Nm of torque. The integrated blocking brake allows vertical or overhung loads to remain stationary when power is removed. Contaminant ingress at the rotating interface is limited by a fitted shaft seal, which helps protect the bearings in dusty or oily environments. The motor uses frame size 065, which helps keep mass and inertia low for fast response while still supporting the rated output. Standard housing surface finish and rotor balancing support use in multi-axis packaging stations, small gantries, and material-handling equipment.
