Product Description:

The MDD071B-N-040-N2T-095GA2 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit supplies commanded torque and speed to indexing tables, pick-and-place axes, and other motion modules in automated production lines. Its standard housing keeps the motor compact enough for crowded equipment bays while still providing the dynamic performance required for closed-loop servo positioning. The motor is well suited for repeated start-stop motion, where stable response and accurate repositioning are important throughout normal operation.

At standstill, the motor can deliver 4.4 Nm of continuous torque, allowing the drive to hold static loads without overheating. During stops or emergency power loss, the integrated blocking brake applies 6.5 Nm so the axis remains fixed until release. That combination is useful in applications where the load must stay in place between commanded moves. Under rated electrical frequency, the rotor reaches a nominal speed of 4000 rpm, which marks the top of the continuous operating range for velocity loops. Mechanical alignment during mounting is aided by a centering pilot of 95 mm, and all power and feedback connectors face side A for straightforward cable routing inside the machine.

Feedback is generated by the integrated multi-turn absolute encoder, so the controller retains position information across multiple revolutions after power is restored. This signal is provided through digital servo feedback (DSF), giving high-resolution data for precise speed and position regulation. A plain shaft with a factory-installed shaft seal supports couplings or pulleys while helping keep contaminants away from internal components. The motor uses size code 071 with motor length B and standard balancing, and a single connector carries both power and sensor leads. Using one connection point keeps the wiring layout compact at the motor body. There is no rear shaft extension, so the non-drive end does not require extra clearance in tight machine spaces.
