MDD041A-N-100-N2G-050GA1
The MDD041A-N-100-N2G-050GA1 is a synchronous servo motor engineered by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical power into precise rotary motion for feed axes, pick-and-place heads, and indexing tables in automated machinery where repeatable motion is required. Its compact frame and high base speed allow integration into assemblies where space is limited, while still supporting fast response and accurate positioning during frequent start-stop cycles. The motor is well suited to applications that need short move times, stable low-speed control, and repeatable stops over long production runs with minimal settling time.
A 50 mm centering diameter mates with standard flange bores, and the connections exit on side A through a front-face connector interface that keeps cable routing accessible. A shaft seal guards the housing against oil spray and helps protect internal parts during continuous operation. Under continuous stall, the motor delivers 0.64 Nm of torque, while a nominal speed of 10,000 rpm permits rapid positioning without gear reduction. Position retention during power loss is handled by an integrated blocking brake that applies 1.2 Nm of holding torque, which helps keep the axis from drifting at standstill. Motion feedback is generated by resolver feedback, providing rotor angle information for current vector control and stable velocity regulation.
The standard housing uses the normal enclosure style of the series and fits compact machine layouts without adding unnecessary bulk. Size code 041 gives a narrow stator diameter suited to light-load axes, while length code A keeps the body short and helps reduce moving mass. The short body is useful where the motor must fit beside guards, sensors, or transfer mechanisms in tightly packed machine zones. Electrical and mechanical terminations are pre-sealed to limit dust or coolant ingress during continuous operation. Compatible digital controllers can use the motor in closed-loop axis applications that require quick, repeatable motion.
