MDD071A-N-040-N2T-095PR0
The MDD071A-N-040-N2T-095PR0 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical input into rotational motion for positioning tasks in automated machinery. The unit follows the A length code and uses standard housing and balancing, which keep the form factor compact while supporting the fast response expected in multi-axis production lines. Its synchronous design supports controlled acceleration and deceleration under servo regulation. That makes it suitable for feed axes, transfer units, and indexing mechanisms that must repeat the same motion path through long production runs.
A centering diameter of 95 mm aligns the motor precisely to adjoining mechanical frames and helps reduce runout at the coupling. At standstill it delivers 2.2 Nm of continuous torque, allowing static load support without overheating. Once energized, the rotor can reach a nominal speed of 4000 rpm, which fits high-cycle indexing or spindle duties. Feedback is transmitted through Digital servo feedback (DSF), so compatible drives receive high-resolution position data for tight velocity loops. All power and signal conductors exit on the right side because the connectors are oriented in that direction, which helps when the motor is installed in compact cabinets or crowded machine sections. This layout also helps keep cable paths organized when neighboring components leave little clearance around the motor.
The shaft profile includes a keyway that helps couplings resist torque spikes during rapid reversals. Rotor position across multiple revolutions is stored by an integrated multiturn absolute encoder, so the axis can return to operation without a homing move after a power interruption. The motor is supplied without a blocking brake, so power-off holding must be provided by drive torque or an external clamp when the application needs it. A shaft seal at the output journal limits dust and coolant ingress toward the bearing set. This combination supports direct coupling to pulleys or gears on axes that need consistent restart behavior after an interruption.
