Product Description:

The MDD071B-N-040-N2T-095PR0 is a brushless synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts electrical command signals into controlled rotary motion for positioning tables, pick-and-place axes, and other industrial automation stages. Its synchronous operating principle supports accurate speed regulation and repeatable positioning during closed-loop motion. A standard housing with internal balancing supports smooth operation, while the keyed shaft end and B-length frame permit direct coupling to moderate-inertia loads without intermediate gear reduction.

At standstill, the rotor can deliver a continuous torque of 4.4 Nm, providing holding force and low-speed process torque. During routine motion, the motor can reach a nominal speed of 4000 rpm, which is the synchronous rate at rated voltage. This operating range suits transfer, indexing, and general servo-axis movement where fast response is required. Mechanical fit is simplified by a centering diameter of 95 mm, which provides a repeatable pilot surface for flange mounting. The power and feedback plugs are positioned on the right side of the end bell, which can simplify cable routing in side-entry layouts. Position data is transmitted through digital servo feedback, allowing the drive to close high-resolution speed and position loops.

An integrated multiturn absolute encoder tracks shaft position over multiple revolutions without battery support, so the axis can retain position information after power loss. This arrangement helps reduce the need for reference travel when the machine returns to operation. The motor is supplied without a blocking brake, so vertical loads must be secured by an external locking device or by drive-held torque when power is removed. A dedicated shaft seal helps limit contamination ingress at the output end and supports cleaner bearing operation. The keyed shaft arrangement corresponds to motor size 071, which keeps inertia low while providing adequate thermal mass for moderate duty cycles.
