Product Description:

The MDD090C-N-040-N2L-130GB0 is a synchronous servo motor built by Bosch Rexroth Indramat and placed within the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts precisely metered current into controlled rotation for axes that demand repeatable motion in assembly lines, pick-and-place gantries, and machine tool spindles. This allows the motor to support accurate positioning, steady speed control, and quick response to changing load conditions during automated operation. The 090 frame designation refers to the stator diameter, while the C length code indicates an intermediate active stack that balances torque output with overall package depth.

The motor centers on a flange with a centering diameter of 130 mm, allowing accurate radial alignment to adjacent mechanics. At standstill, it can deliver 10.4 Nm continuously, which is the maximum continuous torque available at zero speed without overheating. Under rated supply and temperature, it reaches a nominal speed of 4000 rpm, giving high surface velocity for fast cycles. Power and feedback conductors exit on the rear side because the electrical connections are located on Side B of the housing. They are terminated through a single keyed connector interface, which helps keep cable routing compact and orderly inside the machine.

Position and velocity information is returned through digital servo feedback, enabling the drive to close a high-resolution control loop without additional encoders. The rotor is supplied without a blocking brake, so applications that need holding torque must use external mechanical restraint or drive-controlled torque at standstill. The motor comes with a shaft seal, which helps limit lubricant migration and keeps contaminants out of the bearing cavity. Its plain shaft supports backlash-free coupling to pulleys, gears, or clamping hubs.
