Product Description:

The MDD090A-N-040-N2M-130PB1 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it supplies rotational power to automated axes that require closed-loop velocity and position control. The unit’s 090 frame size, A length code, and standard housing support use in machinery that accommodates this motor family, while factory balancing in the standard class allows direct coupling to precision loads without additional correction.

The mechanical interface uses a centering diameter of 130 mm, which aligns the stator flange concentrically with the machine frame. Output speed tops out at 4000 rpm, a value matched to high-throughput packaging and handling tasks. At standstill, the motor can deliver 3.7 Nm continuously, providing stable torque for static holding or low-speed indexing. Power and feedback conductors exit on Side B through a sealed connector, keeping the opposite face free for mounting. Precise multi-turn position data comes from the integrated multiturn absolute encoder, so the controller always knows rotor position even after power loss.

For power-off restraint, a blocking brake supplies 6.5 Nm of mechanical holding torque, letting vertical axes remain stationary without external clamps. Commutation and position loops are closed with digital servo feedback, which transmits high-resolution signals that are not affected by analog drift. The single-ended output shaft is machined with a keyway that locks pulleys or couplings against slip, and a fitted shaft seal limits lubricant migration as well as particulate ingress. Standard housing and connector styles keep the mechanical layout consistent, while the absence of a shaft extension on the non-drive side shortens the overall length for compact enclosures.
