MDD071B-N-060-N2T-095PL1
The MDD071B-N-060-N2T-095PL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Delivered as a motor for digital drive controllers, it is intended to convert commanded current into tightly regulated rotary motion for indexing tables, automated tooling, and material-handling axes on factory lines where repeatable positioning and stable speed control are required during frequent start-stop cycles. The standard housing dissipates heat by natural convection, and standard dynamic balancing keeps vibration within ISO limits during continuous motion and rapid changes in direction. Its synchronous design allows the connected controller to regulate torque, speed, and position with the fast response expected in servo-driven automation equipment.
The motor uses a 95 mm pilot diameter for coaxial mounting, and it has a keyway shaft end to transmit torque to couplings without slippage. Electrical power and feedback are routed on the left through a plug-in connector, which can simplify cable routing where machine guards or adjacent axes limit clearance around the motor body. At the stator, the winding can sustain 4.4 Nm of continuous torque at standstill, and the rotor is rated for a nominal speed of 6000 rpm for high-cycle operation. The pilot fit and keyed shaft provide a straightforward mechanical interface for couplings, pinions, or other driven elements that require accurate alignment at the mounting face.
An integrated brake provides 3.0 Nm of holding torque, clamping the shaft when the enable signal is removed to help hold a parked axis in place. Motion feedback is handled by a compact multiturn absolute encoder, and its position data are transmitted as digital servo feedback so the controller can interpolate multi-turn positions with sub-revolution accuracy and maintain closed-loop position control after power cycling. These devices are housed in the 071 frame size with B length, which balances thermal mass against inertia for agile yet continuous motion in compact machine assemblies. Standard shaft sealing protects the internal bearings from cooling mist and airborne particulates, and the single-ended shaft configuration simplifies mechanical guarding around the drive end.
