Product Description:

The MDD071B-N-040-N2T-095PL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for use with digital drive controllers. As a member of the MDD Synchronous Motors series, it provides regulated rotary motion in automated machines that require consistent velocity tracking and precise position feedback. The integrated multiturn absolute encoder supplies real-time rotor angle data to the drive through its digital servo feedback channel, allowing closed-loop control of speed and torque in packaging lines, material-handling axes, and light machining centers. Because the encoder is absolute and multi-turn, the controller can continue to track shaft position across multiple revolutions without relying on a separate external feedback device.

The motor uses a centering diameter of 95 mm, which helps align the housing accurately to the machine frame. When energized, it can deliver a continuous standstill torque of 4.4 Nm for static positioning duty. The rotor reaches a nominal speed of 4000 rpm, matching drive systems that require fast commanded motion. For emergency stops, a blocking brake provides 3.0 Nm of holding torque after power is removed. Frame size 071 sets the motor envelope, flange pattern, and thermal capacity for this model.

Length code B indicates the second housing depth available in this series, adding winding space without changing the 071 frame size. Power and feedback plugs exit on the left side, which can simplify cable routing when the cabinet is mounted to the right of the axis and can help keep cable bends away from nearby machine structures. The motor includes a shaft seal that helps limit lubricant escape and particle ingress at the keyed shaft end. Dynamic operation remains stable because the rotor is balanced to the standard grade in DIN ISO 21940, and the keyed shaft transfers torque directly to couplings without slip.
