Product Description:

The Bosch Rexroth Indramat MDD071C-N-040-N2T-095PB1 is a synchronous servo unit in the MDD Synchronous Motors series. Built for digital drive controllers, it converts commanded current into precise rotary motion for pick-and-place modules, packaging axes, and other positioning tasks. The 071 frame and C length code provide a compact motor body with useful torque output for dynamic axes. Its synchronous design supports closed-loop motion where repeatable speed and position response are required during frequent starts, stops, and direction changes.

Mechanical alignment is supported by a 95 mm centering diameter, which helps position the flange accurately on gearboxes or mounting plates. Power and feedback conductors exit on side B, so cable routing can stay clear of moving parts, and a keyed connector helps prevent incorrect mating. At standstill, the motor produces 6.6 Nm of continuous torque, allowing stable holding or low-speed feed rates without overheating. Position reporting comes from an integrated multi-turn absolute encoder, and data are transferred as digital servo feedback (DSF) for direct communication with the drive. This feedback arrangement allows the connected controller to monitor rotor position continuously during acceleration, deceleration, and dwell periods. During motion, the rotor reaches a nominal speed of 4000 rpm, matching applications that need fast positioning without requiring an oversized motor.

Additional features support installation on axes that must remain secure at rest. A blocking brake supplies 3.0 Nm of static torque, allowing vertical axes to remain locked when power is removed. There is a shaft seal, so splash coolant cannot migrate along the keyed shaft and contaminate internal bearings. The keyway shaft end supports standard couplings, and the lack of a second shaft extension on side B keeps the rear of the motor compact. This layout helps the motor fit tightly spaced machine frames and enclosed drive assemblies.
