MDD071B-N-040-N2S-095GL2
The MDD071B-N-040-N2S-095GL2 is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Intended for digital drive controllers, it converts commanded currents into precise rotary motion to position or accelerate machine elements in automated cells, gantries, and machine-tool spindles. Closed-loop operation is supported through its integrated feedback interface, letting Indramat drive modules regulate torque and velocity for consistent process quality. This makes the motor suitable for servo-driven axes that require repeatable starts, stops, and speed changes during normal machine operation.
The motor delivers a continuous standstill torque of 4.4 Nm, which indicates how much load it can hold without overheating when the rotor is stationary. Under rated conditions, it reaches 4000 rpm, offering high cycle rates for light- to medium-inertia axes. A 95 mm centering diameter aligns the housing with the mounting flange so radial forces pass into the machine frame. Rotor vibration is controlled by standard balancing, which meets general industrial limits without additional grading. Power and signal leads exit on the left side through a single circular connector, simplifying cabinet wiring. Position data is returned through digital servo feedback (DSF), allowing the controller to correct speed and position errors in real time.
An integrated blocking brake rated at 6.5 Nm locks the rotor during power-off conditions and helps prevent drift on vertical axes. The output end uses a plain shaft with a shaft seal that keeps lubricants inside the housing while helping block dust and coolant splash. The motor has size code 071 and length code B, which keep mass and inertia moderate in tightly spaced multi-axis systems. Connectorized cabling and the standard housing support a compact installation in automated production lines.
