MDD071B-N-040-N2T-095GR1
The MDD071B-N-040-N2T-095GR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Supplied for use with digital drive controllers, it converts controlled current into precise rotary motion for industrial automation axes. This motor type is suited for positioning and speed-controlled applications that require repeatable motion during continuous machine operation. The motor has a 071 frame size with B length, which gives it the mounting pattern and active stack height used for this housing format.
At standstill, the rotor can deliver a continuous torque of 4.4 Nm, which supports sustained load within the motor's thermal capability. Under nominal excitation, the shaft reaches 4000 rpm, providing the speed range needed for rapid indexing and positioning moves. A blocking brake is installed, and its static holding capacity is 3.0 Nm to help prevent axis drift when power is removed. Standard dynamic balancing helps reduce vibration during rotation. A centering pilot of 95 mm maintains coaxial alignment with machine interfaces. Power and feedback lines terminate through a keyed connector, which provides a secure electrical interface, and the housing uses the standard sealed version for convection cooling.
All electrical ports are oriented to the machine's right side, with a connection direction of Right. Position data are transmitted as digital servo feedback (DSF), and rotor angle is measured by an integrated multi-turn absolute encoder, so the drive can identify position after power-up. A shaft seal is fitted to limit lubricant migration, and the motor uses the series' standard shaft end without an extension on side B. Drive torque is transmitted through a plain shaft, which supports clamp couplings and avoids keyway stress concentrations.
