Product Description:

The MDD090C-N-040-N2M-130GB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use with digital drive controllers in industrial automation, it converts controlled armature current into precisely regulated rotary motion for positioning, indexing, and speed-regulated tasks. This motor is suited for machine axes that require repeatable starts, stops, and speed changes during automated operation. Its size 090 frame with length code C provides a compact form while retaining the standard housing and standard balance used for direct installation on machinery.

At its nominal operating point, the rotor reaches 4000 rpm, a speed that supports fast production cycles on servo-driven equipment. The continuous torque available with the shaft locked is 10.4 Nm, which provides solid holding force during dwell periods. Mechanical alignment is simplified by a centering spigot that measures 130 mm in diameter, while the output interface is a plain shaft for couplings or pulleys without keyways. Position data are supplied by an integrated multi-turn absolute encoder, and the circular connector on the rear face helps keep cable routing compact around the motor body. This combination of speed, torque, and feedback supports accurate motion on indexing tables, feed axes, and similar automated assemblies.

The feedback channel uses digital servo feedback, allowing the drive to receive high-resolution position data over a single serial line without separate tachometer wiring. A shaft seal helps protect the motor from lubricant leakage, and the unit is supplied without a blocking brake, so holding torque must come from the driven mechanism or an external clamp when the axis is stopped. All connectors are located on Side B, which leaves the opposite face clear for attachment to gearheads or guards. This layout supports cleaner harness routing and helps keep surrounding machine components unobstructed during installation.
