Product Description:

The MDD090B-N-040-N2L-130PA2 synchronous motor is produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. This AC servo motor is intended for digital drive controllers that require fast positioning and stable speed control in packaging lines, pick-and-place units, and material-handling stations. In operation, it converts controlled electrical input into repeatable rotary motion, while its internal sensing system helps the connected drive correct load changes and maintain the commanded path. The design is suited to compact machine axes that need accurate acceleration, deceleration, and steady running during repeated production cycles.

Its nominal speed of 4000 rpm supports applications that need high cycle rates and quick motion sequences. During stationary clamping or low-speed creep, the motor can deliver 7.2 Nm of continuous torque, which suits the thermal capacity of the B-length housing. A blocking brake at the non-drive end provides 11.0 Nm of holding torque so the axis can remain fixed when the DC bus is switched off. Closed-loop control is supported by digital servo feedback, which sends position data to the controller for accurate velocity and torque regulation. Mechanical output is transferred through a keyway shaft, allowing a positive connection to pulleys, couplings, or gearboxes.

Mounting accuracy is supported by a 130 mm centering diameter that helps align the flange with the machine surface. Power and encoder leads exit on side A, and a sealed connector system routes both interfaces without terminal blocks. A shaft seal protects the front bearing area from lubricants and fine particulates during operation. The 090 frame size with B length keeps the motor compact while still allowing stable running and standard balancing. The single-ended shaft leaves no projection on side B, which helps reduce the total installation depth in confined machine layouts.
