Product Description:

The MDD115B-N-015-R2L-130GL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, the unit converts commanded current into tightly regulated mechanical rotation for gantry axes, indexing tables, and transfer modules in automated plants. Its standard housing supports straightforward installation, and the 115 frame with B length provides a useful balance between thermal capacity and installation depth. That combination suits closed-loop motion tasks that require repeatable acceleration, stable speed control, and accurate positioning during frequent start-stop cycles.

A continuous standstill torque of 38.0 Nm can be delivered indefinitely when the stator temperature remains within the rated limit. During operation, the rotor reaches a nominal speed of 1500 rpm, which suits direct coupling to slower process screws and rollers. Mounting accuracy is supported by the 130 mm centering pilot, and balance class R helps keep residual forces low for smooth running. Power is transmitted through a plain shaft, so backlash-free clamping hubs can be used without the stress concentration associated with a keyway.

Electrical interfaces are routed on the left end shield, where a single angular connector carries phase conductors and Hall lines to reduce cable loops inside the machine frame. Motion feedback is supplied by the integrated digital servo feedback (DSF) module, allowing the drive to read rotor position directly for closed-loop control. The motor is supplied without a blocking brake, so holding force must be provided by motor excitation or the driven mechanism when the axis is stationary. A shaft seal is fitted to help prevent lubricant migration into the stator chamber and to protect internal components during normal machine operation.
