MDD071B-N-060-N2S-095GA1
The MDD071B-N-060-N2S-095GA1 synchronous servo motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a rotary actuator, it works with digital drive controllers to convert electrical commands into precise shaft movement inside automated cells. The frame size 071 and B-length housing provide a compact option for medium-inertia axes that need repeatable speed tracking in packaging, handling, and small machining stations. This motor is suited for feed axes, indexing tables, and transfer units where controlled acceleration and accurate stopping are important. It is commonly used where smooth motion and stable positioning are required through repeated operating cycles.
At standstill, the rotor can supply a continuous torque of 4.4 Nm, letting the axis support static loads without excessive heating. Under dynamic conditions, it reaches a nominal speed of 6000 rpm, so positioning cycles remain short while staying within rated flux. An integrated blocking brake delivers 3.0 Nm of holding torque when power is removed, which helps secure vertical or safety-related axes. Accurate mounting is aided by a centering diameter of 95 mm, which registers the flange to gearboxes or machine plates. Rotor position is returned to the controller through digital servo feedback, allowing tight velocity and position loops during acceleration and deceleration.
The connectors are oriented on Side A, which can simplify cable routing when multiple drives share a common cabinet wall. Power and feedback conductors connect through a sealed connector, and standard dynamic balancing helps limit vibration transfer to adjacent structures. The drive end uses a plain shaft suited for clamp or collet couplings, while a shaft seal helps block oil ingress into the stator air gap. With frame code 071, the motor keeps mass and inertia low for responsive motion in compact machine layouts. The compact housing also helps when the motor must fit near guarding, tooling, or neighboring axis modules.
