Product Description:

The MDD071A-N-030-N2S-095GA0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied for use with digital drive controllers and is intended to deliver closed-loop rotary motion to machine axes and actuators in automated equipment. The design follows the short A length code, which gives the motor a compact stator section for installations with limited space. This motor type is suitable for positioning and speed-controlled tasks where accurate feedback and compact mechanical packaging are needed. Its single-ended plain shaft allows direct coupling to gearboxes or driven elements without a second shaft extension on side B.

At standstill, the motor can deliver a continuous torque of 2.2 Nm, which is the continuous locked-rotor torque the winding can support thermally. Once driven by the controller, it reaches a nominal mechanical speed of 3000 rpm, providing a balance between quick positioning and steady running. Precise rotor position is relayed to the drive through digital servo feedback so the current and velocity loops stay synchronized during operation. This feedback arrangement lets the controller monitor motion continuously during acceleration, holding, and speed changes. A centering diameter of 95 mm aligns the flange with machine mounting faces, while the power and signal leads exit on side A through a connector that keeps the electrical interface compact.

The rotor uses standard balancing, which supports smooth operation with moderate-mass loads. Protection at the drive interface is provided by a shaft seal, helping limit lubricant or coolant ingress when the plain shaft is installed in a gearbox or enclosed drive train. Because the unit is supplied without a blocking brake, any holding function must be provided by the drive or by external clamping hardware. The 071 frame code indicates the motor size used for this housing, and the side A connection layout leaves side B open for airflow around the stator. The standard housing form is suited to enclosed machine assemblies where compact motor placement is important.
