Product Description:

The MDD090A-N-040-N2L-110PL1 is a synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts electrical input into controlled rotary motion for positioning tables, packaging spindles, and general automation axes. Its electromagnetic circuit supports rapid current response, helping closed-loop systems maintain repeatable motion during short cycle operations and frequent speed changes. This makes the motor suitable for packaging equipment, indexing devices, and servo-driven machine modules that must repeat the same path with little deviation. The design also supports steady low-speed behavior and responsive acceleration in compact machine layouts.

At installation, the motor centers on a flange that measures 110 mm in diameter, which helps keep the housing aligned with connected machine parts. Standard dynamic balancing helps reduce vibration that could influence encoder performance at higher speeds. A continuous standstill torque of 3.7 Nm allows the axis to resist static load without excessive heat buildup, and the rotor reaches a nominal speed of 4000 rpm for fast travel moves. Position and velocity data are supplied through digital servo feedback, so the drive can monitor rotor motion directly. For mechanical coupling, the shaft uses a keyway and includes a fitted shaft seal to help keep lubricants and contaminants separated from internal components. The motor has a standard single-ended shaft, so there is no side-B shaft extension.

Holding is provided by an integral blocking brake with 6.5 Nm of static torque when power is removed. Power and feedback leads exit on the left side through a multi-pin connector, which can simplify cable routing where several axes are mounted closely together. The frame is motor size 090 with length code A, giving the motor a compact housing for machines with limited mounting space. This housing size fits narrow columns and transfer units where cable clearance is restricted. The brake is intended for holding at standstill rather than for routine stopping during normal motion.
