Product Description:

The MDD090A-N-030-N2M-130PB2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise rotary motion for positioning, speed, and torque control in automated equipment. Its housing and rotor layout follow the standard format used in this product line, so the unit fits typical machine installations without extra external hardware. This type of motor is commonly applied to feed axes, indexing units, and other servo-driven mechanisms that require repeatable motion from a compact drive package.

The centering shoulder measures 130 mm, giving the flange a fixed locating reference against the machine face. Power and feedback conductors exit on side B through a connector, which helps keep cable routing orderly while preserving a sealed interface. At standstill, the motor can deliver 3.7 Nm of continuous torque for axes that hold a load or move at low speed. Position data comes from an integrated multi-turn absolute encoder, so shaft angle remains available after power is restored. Torque is transmitted through a ground shaft with a keyway, which provides a positive mechanical connection to the driven element. The locating shoulder and shaft arrangement also support accurate alignment between the motor and the coupled load.

An internal blocking brake provides 11.0 Nm of holding torque during power-off conditions, which is useful on vertical or suspended axes. Under rated excitation, the rotor reaches 3000 rpm for applications that require steady speed at moderate inertia. Feedback is exchanged as digital servo feedback, allowing the drive to process position and motion signals with high resolution. The motor uses frame size 090 with an A stack length, balancing compact dimensions with thermal capacity. A shaft seal limits ingress, the motor has a single drive-side shaft end, and the housing uses a standard finish for general industrial service.
