MDD071A-N-040-N2S-095PR1
Bosch Rexroth Indramat builds the MDD071A-N-040-N2S-095PR1, a member of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into controlled torque and speed for automated pick-and-place heads, light conveyors, or auxiliary tooling axes. It is well suited for applications that need accurate starts, stops, and short positioning moves during repeated machine cycles. The A-length housing keeps installation depth low while leaving room for the internal encoder, blocking brake, and keyed shaft used in industrial machinery. When paired with a compatible drive, the motor provides position-regulated motion, and the integrated brake helps hold vertical or suspended loads after power is removed.
The unit supplies a continuous standstill torque of 2.2 Nm, allowing it to hold loads without motion as long as rated current is maintained. For emergency stops or power-off conditions, the blocking brake provides an additional 3.0 Nm of static torque to lock the rotor. A nominal operating speed of 4000 rpm suits medium-speed indexing tasks in assembly cells and similar automated equipment. Rotor position is reported through digital servo feedback (DSF), giving the drive real-time data for closed-loop velocity and torque control during changing loads. All power, signal, and brake lines are routed through a single connector, which helps keep cable routing compact and reduces the number of separate machine connections.
Mechanical integration is aided by the 95 mm centering diameter that aligns the flange to standard motor mounts. Torque is transmitted through a keyway shaft that works with conventional pulleys or couplings. A factory-installed shaft seal helps keep coolant splash and dust away from the front bearing area during normal machine operation. Vibration is controlled by standard balancing, which supports smooth rotation at rated speed. Cables exit on the right side to suit machines that route harnesses along that path, and the compact frame still accommodates both the brake mechanism and the encoder assembly.
