Product Description:

The MDD090A-N-030-N2M-130GR2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it provides rotational power for positioning or velocity-controlled axes in automated machinery. The model uses the 090 frame size with length code A housing and is supplied without a side-B shaft end, reducing overall length. Standard balancing keeps residual vibration low, letting the motor couple directly to gearboxes or belt drives through its plain output shaft.

The mechanical interface includes a centering pilot of 130 mm, which provides a precise reference surface for flange mounting. At standstill, the motor can deliver a continuous torque of 3.7 Nm, which is the steady load it can hold without overheating. During motion, the windings support a nominal speed of 3000 rpm, matching common 50/60 Hz drive outputs through field-oriented control. An integrated blocking brake supplies up to 11.0 Nm of holding torque so suspended loads remain secured when power is removed. The shaft is a plain shaft, allowing couplings or pulleys to slide on without keyways and helping reduce runout in high-cycle applications.

Position information comes from an integrated multiturn absolute encoder, and the winding signals are returned to the drive through digital servo feedback so the controller can close position and velocity loops with high bandwidth. Power and feedback conductors terminate through a single connector that faces the right side of the housing, which can simplify cable routing inside compact enclosures. A shaft seal helps prevent coolant or oil ingress at the output end. The housing is suitable for typical shop contaminants. This motor is used on packaging heads, loading slides, and indexing tables that require repeatable closed-loop motion.
