Product Description:

The MDD090C-N-020-N2M-130PR1 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 delivers closed-loop rotary motion to automated axes that need accurate velocity and position control. In packaging machines, material-handling stations, and other cyclic equipment, it converts commanded current from an inverter into stable mechanical output while returning position data to the drive. This arrangement supports repeatable motion in applications that depend on steady acceleration, controlled deceleration, and accurate positioning over repeated cycles.

Its continuous torque at standstill is 10.4 Nm, allowing the shaft to hold loads without movement while thermal limits are observed. The motor has a nominal operating speed of 2000 rpm, which is the rated rotation when voltage, current, and cooling are at design values. The unit carries an integrated multi-turn absolute encoder that records shaft angle across multiple revolutions. Data are transmitted through digital servo feedback (DSF) for precise current, speed, and position control. When incoming power is removed, a blocking brake supplies 6.5 Nm of static torque to keep the axis stationary. A shaft machined with a keyway accepts standard couplings, and alignment in the mounting interface is provided by a 130 mm centering diameter. Power, brake, and feedback conductors exit to the right, which supports layouts where the drive is positioned to the left of the motor.

The motor uses length code C within size 090, which suits medium-torque applications without requiring a larger frame. Dynamic forces are balanced to the manufacturer’s standard grade, and the housing uses a standard cooling surface to remove heat during regular operation. A shaft seal is fitted to help restrict contaminant ingress, and the side B end is left blank to save space near adjacent machine parts. Electrical terminations are completed through a connector, which allows quick attachment of the cable assembly without rewiring individual conductors.
