Product Description:

The MDD090B-N-030-N2L-110PA1 is an AC synchronous servomotor built by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into precise motion for positioning and cyclic tasks in automated machinery. The design integrates electronic commutation and feedback so the servo loop inside the drive can regulate torque and velocity with minimal delay. This makes the unit suitable for axes that need accurate starts, stops, and repeated speed changes during automated production. Its 090 frame geometry keeps the motor compact for machines that use this housing size.

For continuous duty at standstill, the motor develops 7.2 Nm of electromagnetic torque, allowing stable holding or low-speed feed operations without overheating. When spinning, it reaches a nominal mechanical speed of 3000 rpm, matching drive settings used in pick-and-place axes and packaging stations. Position retention during power loss is provided by an integrated brake rated at 6.5 Nm, which clamps the shaft when the coil is de-energized. Closed-loop accuracy comes from its digital servo feedback (DSF) encoder, which returns position data directly to the controller for continuous correction. Mechanical centering against the machine flange is secured by a 110 mm pilot diameter, helping keep shaft alignment accurate during repetitive motion.

All power, brake, and feedback lines exit on side A through a keyed connector, which helps simplify cable routing in compact cabinets. The output shaft has a keyway for slip-free coupling to pulleys or gearboxes, and a shaft seal helps keep lubricant inside the housing when the motor is installed in oil-mist environments. The rotor uses standard balancing, which minimizes vibration at full speed and helps the servo maintain commanded profiles. The balanced rotor helps reduce oscillation during rapid acceleration and deceleration. Grouping the electrical interfaces on one end of the motor can reduce cable crossing near adjacent machine elements.
