Product Description:

The MDD071B-N-040-N2S-095PA1 is a brushless AC servo motor built by Bosch Rexroth Indramat and part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into precise rotary motion for handling modules, packaging equipment, and machine-tool axes. The brushless design supports repeatable response during frequent start-stop motion, and the standard housing and balancing arrangement helps the motor fit machinery that is already arranged for this product line.

The motor provides a continuous standstill torque of 4.4 Nm while the stator remains energized. Its maximum speed is 4000 rpm, which gives the axis a broad operating range for rapid moves and short positioning cycles. Position information is returned through digital servo feedback, allowing the connected drive to maintain closed-loop control with precise speed and position correction. A centering diameter of 95 mm aligns the motor accurately on the machine interface, and a plug-in connector allows cable attachment without opening the housing. The housing uses frame size 071 with length code B, which keeps the motor within the expected envelope for this model.

Power and feedback connections are arranged on Side A, which helps when cable routing approaches the motor from one direction. A holding brake rated at 3.0 Nm keeps the axis in place when power is removed, which is useful on vertical or suspended loads. The output shaft uses a keyway for positive torque transmission to couplings or driven elements, and the shaft is built in a single-ended form to avoid interference on the opposite side. A shaft seal helps keep coolant, dust, and other contaminants away from the bearing chamber. This helps protect the bearing area during operation in enclosed industrial machinery.
