Product Description:

The MDD090C-N-020-N2L-110GR2 is a synchronous servo motor from Bosch Rexroth Indramat that belongs to the MDD Synchronous Motors series. As a motor for digital drive controllers, it is installed in production lines, packaging units, and material-handling axes where closed-loop speed and position control are required. Its electromagnetic profile is tailored for medium inertia loads commonly found in indexing tables, gantry drives, and automated storage equipment. It is intended for machine axes that must start, stop, and reverse smoothly while staying synchronized with the commanded motion profile. That makes it suitable for applications that need responsive motion without using an oversized frame.

The motor’s mechanical envelope follows size 090 and length code C. The standard housing and balancing allow direct mounting on gearboxes or machine frames through the centering pilot of 110 mm. All power and feedback leads exit on the right side, and the motor uses a keyed plug-in connector for straightforward cable routing. Speed reference is maintained with the integrated Digital servo feedback (DSF), which transmits position data to the drive for closed-loop control. The feedback channel allows the controller to monitor rotor position and speed throughout operation. Under rated excitation, the rotor reaches a nominal speed of 2000 rpm. At standstill, the electromagnetic design sustains a continuous torque of 10.4 Nm without exceeding thermal limits.

For holding and emergency stop duties, the motor is supplied with a blocking brake that delivers 11.0 Nm of static torque when 24 V is applied. The brake assists with load holding when motion is stopped and power to the axis is removed. The power interface uses a sealed connector, and the rotor journal uses a plain shaft without a secondary end on side B. A molded elastomer barrier is fitted at the bearing area, so the unit is supplied with a shaft seal. This arrangement helps limit lubricant loss and protects the bearing area after installation.
