Product Description:

The MDD093D-N-040-N2M-110PB1 synchronous servo motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, this motor translates regulated three-phase current into controlled torque and velocity for positioning tables, packaging stations, and machining centers in industrial automation. Its electromagnetic design supports cyclic acceleration, deceleration, and stall holding required in indexing or contouring tasks, while the integrated position sensor allows the drive to verify motion without external encoders. Because it is intended for digital control, it suits applications that require repeatable motion during frequent starts, stops, and speed changes.

The motor’s nominal speed is 4000 rpm, enabling short cycle times on linear transfer systems. At standstill it can exert 24.0 Nm of continuous torque, so the axis can hold demanding loads at zero speed without overheating. A centering diameter of 110 mm aligns the flange accurately to the machine frame, reducing radial runout during coupling. Frame size 093 with length code D gives the motor a larger active core for this housing class and supports the thermal capacity needed for cyclic duty. Residual vibration is limited by standard dynamic balancing, and the housing follows the standard enclosure outline for this family. All power and feedback plugs exit on Side B through a sealed connector, which helps keep cable routing clear when the motor is installed near guards or machine frames. The shaft is present only on the drive end, and a factory-installed shaft seal keeps grease inside the bearing cavity while helping block contaminants.

The integrated multiturn absolute encoder reports rotor angle and revolution count, and its data is carried on the digital servo feedback interface for closed-loop regulation. This arrangement allows the controller to retain position information after a power cycle and supports accurate commutation as motion restarts. A blocking brake secures the shaft with 11 Nm of static torque during power-off conditions, which helps keep vertical or indexed loads from drifting. The drive-side shaft carries a machined keyway, allowing a rigid, slip-free connection to pulleys, couplings, or gears.
