Product Description:

The MDD071B-N-030-N2T-095PB1 is a synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended to act as the rotary actuator for digital drive controllers, converting drive current into precise shaft motion for pick-and-place axes, conveyor segments, or tool spindles on automated lines. The motor's mechanical footprint and electrical interface are optimized for installation in multi-axis assemblies.

It develops a continuous standstill torque of 4.4 Nm, allowing the shaft to hold load without movement while current stays within thermal limits. During acceleration or emergency stopping, a built-in blocking brake supplies a static holding capacity of 3.0 Nm, preventing back-drive when power is removed. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, which suits medium-speed positioning tasks. Accurate mechanical alignment is supported by a centering diameter of 95 mm, which seats the front flange concentrically to connected machinery. Power and feedback conductors are routed on side B, simplifying cabinet layout when multiple motors share a common mounting face.

The shaft end has a keyway for positive torque transmission, which reduces reliance on clamp-style couplings. Closed-loop operation is achieved with an integrated multiturn absolute encoder that reports position over digital servo feedback channels, so the drive can retain position information after power loss. The motor has a size code of 071 and a length code of B, which indicate the laminated core dimensions, while the standard housing and balancing class help limit vibration. A shaft seal protects the output bearing area, and the connector-based connection type supports quick cable attachment. Because the shaft is present only on the drive side, the rear remains clear for cable routing and cooling airflow.
