The MDD065A-N-040-N2L-095GB1 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. This compact rotary unit is supplied for integration with digital drive controllers, where it converts electrical command signals into precise mechanical motion for positioning, indexing, and velocity-controlled axes on automated machinery.
At zero speed the motor can deliver a continuous torque of 0.8 Nm, a value that defines the sustained holding or low-speed driving capability without excessive heating. Under rated electrical frequency it reaches a nominal speed of 4000 min⁻¹, allowing fast cycle times in pick-and-place or spindle applications. Mechanical retention during power loss is provided because the unit is fitted with a blocking brake; that brake secures the shaft using a static torque of 3.0 Nm. Rotor position is monitored through digital servo feedback, enabling the controller to close high-resolution motion loops and maintain commanded trajectories during transient load changes.
The motor’s flange centers on a 95 mm pilot diameter, ensuring coaxial alignment with gearboxes or machine frames. Power and feedback conductors exit on Side B, simplifying cabinet routing when the opposite face is inaccessible. A factory-installed shaft seal blocks coolant spray and fine dust, and the drive end employs a plain shaft so radial couplings or pulleys can be mounted without keyway stress concentrations. Standard rotor balancing minimizes vibration, and the design follows size code 065, which sets the stator diameter and winding envelope for compatibility with drives sized for moderate continuous current.
