Product Description:

The MDD090A-N-030-N2L-110GL2 is a synchronous servo motor built by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the motor converts electrical command signals into precise rotary motion for positioning, feed, and spindle axes in automated machinery. Its synchronous design supports accurate speed regulation and repeatable motion in applications that cycle frequently or require stable response across changing loads. It also incorporates mechanical features that allow direct integration into enclosed machine frames while maintaining consistent velocity and torque delivery during operation.

At standstill, the motor can deliver 3.7 Nm continuously; this is the sustained torque available for holding or slow-speed moves without overheating. During dynamic deceleration, a blocking brake supplies up to 11.0 Nm, helping retain the load when power is removed. Velocity control centers on a nominal speed of 3000 rpm, which suits common servo operating ranges. Position feedback is generated through digital servo feedback, enabling closed-loop regulation with precise position tracking. Mechanical alignment is aided by a 110 mm centering diameter that seats the housing concentrically at the drive end. The driven element connects through a plain shaft, which accepts standard couplings without keys or splines.

Installation is simplified because the power and encoder connectors are mounted on the left side. This arrangement allows parallel cable routing when several motors share a machine column. With a frame size of 090 and a length designation of A, the unit keeps a short body within the dimensional envelope used for medium-torque axes. Standard dynamic balancing limits residual vibration, a shaft seal helps prevent lubricant escape, and the housing remains in the standard protection category for use in dry zones or sealed cabinets.
