Product Description:

The MDD090C-N-030-N2L-130GA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies closed-loop motion in production lines, pick-and-place stations, and other axes that need precise velocity and position control. The unit uses a standard housing with standard rotor balancing, so it can be mounted without additional counterweights, and its plain shaft transmits torque directly to couplings or gear stages. In automated equipment, this layout supports repeatable starts, stops, and speed changes during continuous duty. It is suited to axes that must alternate between steady running and short positioning moves without losing control accuracy.

At standstill the motor delivers a continuous torque of 10.4 Nm, allowing it to hold process loads without overheating. During normal operation it reaches a nominal speed of 3000 rpm, which supports high cycle rates in automated axes. Frame size code 090 indicates the stator diameter, while length code C indicates the active stack height. Together, these dimensions set the motor's thermal capacity and output class. All electrical terminations are brought out on the front because the connections are on Side A, and a molded connector simplifies cabling in compact machine layouts. Standard dynamic balancing helps limit vibration at top speed, and the housing style matches other MDD motors used on the same machine platform.

For power-off holding, a blocking brake is integrated and supplies a torque of 11.0 Nm, which helps prevent axis drift on vertical loads. Precise flange alignment is aided by a centering diameter of 130 mm, and a factory-installed shaft seal protects the bearing cavity from coolant splash or airborne dust. Position data are returned through digital servo feedback (DSF), allowing the drive to correct position errors within one control loop. The motor uses a single-ended shaft on the working side only, leaving space behind the rotor for the brake and feedback components. This arrangement keeps the rear section dedicated to internal motor elements instead of an additional shaft extension.
