Product Description:

The MDD090C-N-040-N2M-130GA0 is a synchronous motor built by Bosch Rexroth Indramat for installation in digital drive systems. It belongs to the MDD Synchronous Motors series and is designed for digital drive controllers. Within automated machining cells or material-handling axes, the unit converts electrical input from the drive into precise rotary motion that can be coordinated with servo loops. Its C-length frame and 090 size stator suit medium-inertia applications that need quick acceleration without excess mass.

At rest, the motor can deliver a continuous torque of 10.4 Nm, allowing it to support static loads without overheating. When energized at rated frequency, it reaches a nominal speed of 4000 rpm, so linear travel can be synchronized closely with cycle timing in pick-and-place systems. Mechanical mounting is based on a centering pilot of 130 mm, and its rotor and shaft use standard dynamic balancing to minimize vibration. Power, feedback, and brake leads exit on side A through a single industrial connector, a layout that simplifies cabinet wiring in compact machines. The C-length housing keeps overall mass moderate while the standard enclosure protects the winding set from shop contaminants.

Position data are generated by an integrated multi-turn absolute encoder and transmitted as digital servo feedback (DSF), letting the controller index the rotor without loss of count after power cycles. The drive side uses a plain shaft with a fitted shaft seal to keep lubricant in and coolant spray out, while the rear of the rotor is left without a side B shaft end to reduce tooling interference. Because the unit is supplied without a blocking brake, axis holding torque during power-off must be provided by the drive or an external clamp. The standard aluminum housing helps dissipate heat during operation.
