Product Description:

The MDD115D-N-020-N2L-180GB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers in automated machining centers, material-handling gantries, and other multi-axis systems. By translating regulated three-phase power into precise rotary motion, the motor supplies controllable torque and speed so production equipment can execute repeatable positioning and cycle sequences in industrial automation. This type of closed-loop motor is suited to axes that require stable response during acceleration, deceleration, and repeated positioning moves.

The motor delivers a continuous standstill torque of 57.0 Nm, so it can hold or slowly index substantial loads without thermal derating. When driven at its rated electrical frequency, the rotor reaches a nominal velocity of 2000 rpm, which supports medium-speed direct-drive layouts. A centering pilot of 180 mm ensures concentric alignment to adjacent mechanical components, while power and feedback cables exit toward Side B so cable routing can be kept away from tooling zones. Both conductors terminate on a single industrial Connector, which keeps the motor interface compact and directs both connections through one entry point.

Dynamic accuracy is enhanced by integrated digital servo feedback, which reports high-resolution position data to the controller for closed-loop regulation. The output element is a plain shaft that mates with standard couplings, and a shaft seal helps limit lubricant escape at the rotating interface. Built on frame size 115 with a D-length lamination stack, the model offers increased active copper for higher torque density. Because the unit is supplied without a blocking brake, any requirement for mechanical holding under power-off conditions must be handled by an external clamp or by drive-generated holding torque. The sealed shaft area also supports use in machines where the coupling end may be exposed to dust or light contamination.
