Product Description:

The MDD090A-N-040-N2L-110GL1 is a servo unit manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is a motor for digital drive controllers, so it converts drive commands into controlled rotation for positioning tables, pick-and-place heads, or packaging spindles. Its standardized mechanical length code, centering features, and connector interface align with other modules in the Rexroth drive platform, allowing straightforward installation in existing machine layouts. This arrangement supports repeatable speed and position control in automated equipment that runs frequent starts, stops, and direction changes.

With a continuous standstill torque of 3.7 Nm, the motor can hold static loads or accelerate lightweight mechanisms without gearbox assistance. During operation it reaches a nominal speed of 4000 rpm, which suits high-cycle packaging or textile lines that require rapid reversals. A blocking brake integrated at the non-drive end supplies up to 6.5 Nm of holding torque for vertical axes when power is removed. Position data is returned through digital servo feedback, allowing the drive controller to maintain closed-loop motion with accurate response during acceleration and dwell periods. The centering shoulder has a diameter of 110 mm, which helps seat the motor concentrically against mating machine surfaces. The housing uses aluminum construction and standard dynamic balancing to support smooth running during continuous motion.

The electrical power and feedback connectors exit on the left side, which can simplify cable routing when the motor is installed on gantry beams or inside guarded machine sections. A plain shaft without a keyway is supplied, so torque is transferred through friction-fit couplings that help reduce backlash at the connection point. To protect the bearing grease and stator windings from airborne coolant or dust, a shaft seal is fitted at the output end. The frame is assigned size 090, keeping the overall diameter moderate while leaving enough core length for the A-length stack and its related thermal capacity. This combination supports compact mounting where surrounding space is limited but precise servo motion is still required.
