Product Description:

The MDD090A-N-020-N2M-110GB1 belongs to the MDD Synchronous Motors series from Bosch Rexroth Indramat and is used with digital drive controllers in automated machinery. The unit converts drive current into controlled mechanical rotation, allowing closed-loop positioning and speed regulation when paired with a compatible Indramat drive. Typical applications include packaging axes, pick-and-place modules, and material-handling equipment that require repeatable motion profiles. This makes it suitable for axes that must start, stop, and reverse with predictable motion behavior during repeated machine cycles.

The motor delivers a continuous standstill torque of 3.7 Nm, giving the drive system enough static force for holding or low-speed indexing tasks. Its nominal operating speed is 2000 rpm, so the shaft can reach that speed during normal operation. An integrated blocking brake supplies 6.5 Nm of holding torque to secure vertical loads when power is removed. Mounting accuracy is supported by a 110 mm centering diameter that fits the flange geometry of this frame size. Position and velocity data are transmitted through digital servo feedback, allowing fast closed-loop response during acceleration and speed changes. Standard balancing helps limit radial vibration, and the A length keeps moving mass relatively low for applications that benefit from reduced inertia.

An integrated multiturn absolute encoder stores position over multiple revolutions, so a reference run is not required after a power cycle. Power and feedback conductors exit on Side B through a keyed connector, which keeps cable routing organized at the connection point. A dedicated shaft seal protects the interior bearing area from coolant mist and similar contamination. The output end uses a plain shaft without a keyway, which suits backlash-free clamping hubs on precision couplings. The motor uses standard protection and cooling arrangements, and its single-ended design omits a rear shaft to keep the overall depth compact while leaving more clearance behind the motor in tight machine layouts.
