Product Description:

The MDD090C-N-020-N2L-110PA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where commanded current is converted into precise rotary motion for industrial automation axes, material-handling modules, and machine-tool feeds. Because it is a synchronous design, rotor motion stays coordinated with the controlled stator field during normal operation. This helps the motor support accurate speed regulation and repeatable positioning in closed-loop motion systems.

This motor can sustain a continuous standstill torque of 10.4 Nm, allowing it to hold static loads without overheating during rated operation. Under rated excitation, it reaches a nominal speed of 2000 rpm, providing a stable operating point for applications that require controlled motion. The integrated blocking brake supplies 6.5 Nm of torque to hold the shaft when power is removed. A centering diameter of 110 mm aligns the flange with machine housings, while a keyway shaft supports torque transmission through keyed couplings. The motor uses standard balancing and a standard housing configuration for the 090 frame size, and it has a single-ended shaft with no extension on side B to save space.

Power and feedback conductors are routed on the motor's A-side through a keyed connector, which keeps the electrical interface compact and secure. Position information is supplied by digital servo feedback (DSF), allowing the drive to monitor rotor movement continuously during speed and position control. A factory-installed shaft seal helps limit the entry of dust or lubricants at the coupling point. Routing both electrical interfaces on one face can simplify cable management in compact machine layouts. This arrangement is useful where the motor is mounted close to guards, slides, or gearbox housings.
