Product Description:

Bosch Rexroth Indramat supplies the MDD071C-N-040-N2S-095GB1, a synchronous servo motor in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise rotary motion for positioning, conveying, or tooling axes in automated machines. The model integrates with Indramat drive electronics and uses internal feedback to support closed-loop speed and torque control. Its mechanical format suits compact multi-axis layouts, and the motor is intended for medium-inertia loads that need fast acceleration and accurate stopping.

The motor’s continuous stall capability is 6.6 Nm, allowing it to hold load at standstill without exceeding its continuous thermal limit. During motion it can reach a nominal speed of 4000 rpm, which supports fast cycle times on indexing and transfer axes. Power and encoder leads exit on side B, and a single circular connector simplifies wiring while helping keep the stator enclosure closed. A centering pilot of 95 mm locates the flange concentrically to the driven equipment, which helps reduce misalignment during installation. Standard dynamic balancing helps limit vibration and bearing load at higher shaft speeds.

A blocking brake rated at 3.0 Nm secures the shaft when drive power is removed, which is useful on vertical axes and other applications that must resist drift at rest. Position data are returned through digital servo feedback (DSF), so the controller receives the rotor information needed for precise regulation. The frame designation 071 identifies the motor size, and a plain shaft with a shaft seal supports direct coupling while helping keep contaminants away from the bearing area. The C length code gives the motor a medium body length in this series, and the rear side is built without a second shaft end.
