MDD065A-N-040-N2M-095GL1
Bosch Rexroth Indramat manufactures the MDD065A-N-040-N2M-095GL1, a member of the MDD Synchronous Motors series. This motor is intended for digital drive controllers where closed-loop motion is required on packaging lines, assembly cells, or handling modules. Its job is to translate drive current into precise rotary motion so that automated axes can follow commanded positions and velocities with accurate repeatability. The compact synchronous design makes it suitable for installations where responsive speed control and reliable position tracking are needed within a limited machine envelope.
The motor delivers a continuous standstill torque of 0.8 Nm, meaning it can hold that load indefinitely without exceeding its thermal limits. During operation, it can rotate at a nominal speed of 4000 rpm, which suits high-speed positioning tasks driven by modern servo inverters. Accurate mechanical alignment is supported by a centering diameter of 95 mm, allowing repeatable mounting on gearboxes or machine frames. Power and feedback conductors exit on the left side, which can simplify cable routing in cabinets arranged for that orientation. For multi-cycle positioning without homing, an integrated multiturn absolute encoder tracks revolutions even when the supply is removed and sends position data directly to the drive. This feedback arrangement helps the controller maintain stable motion during indexing, speed changes, and short settling movements.
Dynamic stopping capability is provided by a blocking brake rated at 3.0 Nm, so vertical or load-holding axes remain secure when power is off. A plain shaft couples to couplings or pulleys without keyways, which can help reduce runout and simplify assembly. Electrical termination uses a sealed connector, protecting the internal connection points from contamination while keeping installation straightforward. Position information reaches the controller through digital servo feedback (DSF), enabling high-resolution control and stable velocity regulation. The motor also includes a shaft seal, a standard housing, motor length code A, and standard balancing for regular factory operation.
