Product Description:

The MDD071B-N-030-N2T-095GL0 synchronous motor is manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Built as a motor for digital drive controllers, it converts controlled AC from the inverter into accurate rotary motion for axes that demand repeatable positioning in automated assembly, pick-and-place stations, and web-handling lines. By integrating feedback hardware inside the stator, the unit reduces external components and supports compact machine layouts where space and cable routing are constrained.

At the mechanical interface, a centering diameter of 95 mm aligns the flange to adjoining machine frames, while standard balancing keeps residual vibration within industrial limits. The electromagnetic core supplies a continuous standstill torque of 4.4 Nm, allowing the axis to hold static loads without excess heating. Under rated excitation, the rotor reaches 3000 rpm, providing suitable surface speed for medium-inertia applications. Position information is delivered by an integrated multi-turn absolute encoder that retains turn count during power loss, eliminating homing cycles. Power and feedback conductors exit on the left side through a sealed connector, and because the unit is supplied without a blocking brake, any holding action must be furnished by the drive or an external mechanism.

Feedback signals are transmitted as Digital servo feedback (DSF), enabling high-resolution position data for tight loop gains and smooth velocity control. The plain output shaft includes a shaft seal that restricts lubricant migration into the motor interior, and the design omits a side-B extension so only the main face carries load. Geometric proportions correspond to size 071, and the active magnetic stack follows length code B. These values set the mounting pattern and thermal capacity within the MDD product line, while the left-side connector orientation permits short cable runs to cabinet-mounted inverters.
