MDD071B-N-040-N2S-095PL1
The MDD071B-N-040-N2S-095PL1 is a synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts commanded current into precise rotary motion for positioning, conveying, and tooling axes in industrial automation. Its standard housing and integrated shaft seal allow installation in typical machine-frame or cabinet locations without requiring an added protective enclosure.
The motor delivers a continuous standstill torque of 4.4 Nm, so it can hold or slowly move loads for long periods without overheating. Once in motion, it can reach a nominal speed of 4000 rpm, which is the rated operating speed of the motor. A blocking brake inside the endbell provides 3.0 Nm of holding torque when power is removed, which helps prevent back-driving on vertical or suspended axes. Position and velocity signals are returned through digital servo feedback (DSF), allowing the connected drive to regulate motion in a closed loop. Mechanical alignment is assisted by a centering flange diameter of 95 mm, which helps the motor seat accurately against standard mounting surfaces and couplings.
Cables exit on the left side, which can simplify routing where nearby components limit access around the motor body. The power connection uses a keyed industrial connector, so the motor can be connected without hardwiring the power leads directly into the housing. Torque is transmitted through a single-ended shaft with a precision-ground keyway, which helps couplings and pulleys resist slip under load. The housing uses length code B, giving the motor a consistent body length for installations with limited mounting depth. Standard dynamic balancing helps reduce vibration during operation, and the shaft seal helps keep coolant and dust away from internal components.
