MDD071B-N-030-N2S-095PL0
The MDD071B-N-030-N2S-095PL0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into controlled mechanical rotation for positioning and speed tasks in industrial automation equipment. Because it is intended for use with a digital drive controller, current, speed, and position loops can be coordinated by the external control system during start, run, and stop conditions. This arrangement supports repeatable motion in packaging, handling, and general automation equipment. Its housing follows the standard configuration and the unit is supplied without a blocking brake, so any holding function must come from the drive or external mechanical components.
The size code 071 places the motor in a mid-range frame suitable for moderate-load axes. At a nominal speed of 3000 rpm, it can run with common drive settings while maintaining stable velocity through electronic regulation. A continuous standstill torque of 4.4 Nm gives the motor usable force for static holding under drive control and for low-speed feed moves. Power and feedback conductors exit on the left side through a plug-in connection, which can simplify cable routing where space is limited near guards or machine structures. Rotor position is reported through digital servo feedback (DSF), allowing high-resolution commutation and responsive speed control during acceleration and deceleration.
Mounting accuracy relies on a centering diameter of 95 mm that aligns the motor face to the machine frame. Electrical terminations are made through a keyed connector, which helps keep installation orientation consistent at the interface. A fitted shaft seal helps block coolant spray and dust during washdown use, and the output shaft uses a keyway so torque is transferred without slip under reversing loads. The centering feature also helps maintain concentric alignment between the motor and the driven assembly, which can reduce coupling stress during continuous operation. The motor uses a single-ended shaft layout and standard balancing, which helps maintain smooth rotation while keeping the overall package compact.
