Product Description:

The MDD071B-N-060-N2T-095GA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts commanded current into precise rotary motion for indexing tables, gantry axes, and other automated machinery. Its compact 071 frame and B-length body suit installations that need rapid acceleration and tight position control without taking excessive space. Because it is a synchronous design, it supports accurate speed regulation and repeatable positioning when paired with a compatible control loop.

In continuous stall conditions, the motor can supply 4.4 Nm of torque without exceeding rated winding temperature, giving stable force for holding or slow moves. A nominal speed of 6000 rpm gives the drive a high operating speed for matching gear ratios and load inertia. The flange’s centering diameter is 95 mm, providing a reference surface for concentric mounting. Power and feedback conductors exit on side A, and termination is made through a single circular connector to simplify cable routing. This arrangement keeps the electrical connection concentrated at one outlet point for cleaner cable management. Standard rotor balancing helps reduce vibration at high speed, and the housing is supplied in a standard uncooled form for applications that do not require forced cooling.

A blocking brake rated at 6.5 Nm is fitted to hold the load when the drive is disabled, and a shaft seal helps limit contaminant entry. Position data are supplied by an integrated multi-turn absolute encoder, and the drive reads this through digital servo feedback (DSF) for closed-loop control without external resolvers. The encoder system gives the controller position information immediately after power-up, which is useful on axes that must resume motion without a homing cycle. Mechanical power is transmitted through a plain shaft without a side-B extension, which suits clamping hubs or pulleys. This arrangement is appropriate for direct machine integration where a second shaft end is not needed.
