Product Description:

The MDD090B-N-040-N2L-130GR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts electrical energy into controlled rotary motion for positioning axes, feed systems, and speed-regulated mechanisms in automated machinery. The size 090 construction and B length give it a mid-frame envelope that fits compact machine spaces while still supporting stable mounting and everyday industrial motion tasks. This makes it suitable for packaging equipment, transfer systems, and other servo-driven assemblies that rely on accurate speed and position response.

The motor provides a continuous standstill torque of 7.2 Nm, allowing closed-loop control to hold loads without overheating during stationary operation. During motion, the rotor reaches a nominal speed of 4000 rpm, which suits fast indexing cycles and responsive axis movement. Accurate mounting is supported by a centering diameter of 130 mm, which helps seat the motor correctly against the mating machine plate. Position data is returned through digital servo feedback (DSF), so the drive can adjust current in real time as load conditions change. The motor uses a plain shaft, and the rotor has standard dynamic balancing to reduce residual vibration during repeated starts, stops, and reversals.

Power and feedback lines exit to the right through a keyed connector, which helps organize cable routing where side access is preferred and keeps electrical connections grouped at one outlet point. The motor has a shaft seal that helps keep splash away from the bearing cavity during normal machine operation. It is supplied without a blocking brake, which reduces rotor inertia and leaves static holding to an external brake or drive-generated holding torque when the axis must remain fixed. The shaft is single-ended at side B, so pulleys, couplings, or gearboxes can be mounted directly on the standard output end without an additional extension.
