Product Description:

The MDD090C-N-040-N2L-130GA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive commands into rotational motion for positioning and speed-regulated axes in automated machinery. In service, the motor works with closed-loop control so the drive can correct speed and position as operating conditions change. The unit uses the standard housing and balancing for this product line, and its C length with the 090 frame size creates a compact actuator for installations where mounting space is limited.

At the mechanical interface, the centering pilot has a diameter of 130 mm. This surface registers the motor precisely against a gearbox or machine plate so concentricity errors remain low. During static operation, the rotor can generate 10.4 Nm of continuous torque, which is the steady load the motor can hold without additional cooling. When power is removed, a blocking brake rated at 11.0 Nm clamps the shaft to secure suspended or driven masses. Under rated electrical frequency, the rotor reaches a nominal speed of 4000 rpm, allowing high cycle rates in servo loops. Contaminants are excluded by a shaft seal, which helps keep lubrication intact during prolonged duty.

Electrical and feedback conductors exit on Side A through a keyed connector. This arrangement simplifies cable runs when the motor is mounted deep inside a machine frame and keeps the connection point accessible from one side. Power is transmitted through a plain shaft that omits a secondary shaft on side B, reducing space requirements and limiting potential leak paths around the front seal. Position data is returned to the drive by digital servo feedback, enabling quick commutation adjustments as torque demand fluctuates. Because the feedback device is integrated into the motor, the connected controller can monitor rotor position continuously during acceleration, holding, and speed regulation.
