Product Description:

The MDD090C-N-020-N2M-130PA2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it delivers position-controlled rotary motion to axes on automated machinery and transfer lines. The unit uses a standard housing with standard dynamic balancing, so it can be mounted directly to a machine frame without added vibration hardware. Its mechanical interface matches common series mounting arrangements, which helps it integrate into compact servo-driven equipment.

During continuous duty, the motor reaches a nominal speed of 2000 rpm, which gives the connected drive a practical operating range for indexing and feed applications. At standstill, it can provide 10.4 Nm of continuous torque, allowing the axis to hold steady loads without overheating. Position and velocity data are returned through Digital servo feedback (DSF) generated by an integrated multiturn absolute encoder, so the controller can track shaft movement over multiple revolutions after startup. A centering diameter of 130 mm keeps the flange aligned with the driven machine element. Power and feedback leads exit on side A through a sealed connector, which helps keep cable routing orderly and protects the connection area from splash and dust.

For emergency stops and vertical axes, the motor is supplied with a blocking brake; this spring-applied element clamps the shaft with 11.0 Nm of torque when power is removed. The output shaft uses a keyway profile so couplings can transmit torque without slip, and the front end is fitted with a shaft seal to reduce coolant entry. Because the rotor is single-ended, there is no shaft extension on side B, which reduces the space needed behind the motor. Frame size 090 and length code C indicate the motor’s active core length, while the standard housing finish matches other MDD motors used in shared enclosures.
