Product Description:

The MDD090A-N-040-N2L-130GR2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is categorized as a motor for digital drive controllers and is installed in industrial automation axes where electronic drives regulate velocity and position. By combining permanent-magnet excitation with real-time current control, the unit converts electrical energy into precise rotary motion for packaging, material handling, and assembly equipment.

Mechanical and mounting parameters describe how the motor is integrated. A continuous standstill torque of 3.7 Nm indicates the load it can support without rotation while energized. The rotor can reach a nominal speed of 4000 rpm, providing a balance between rapid indexing and thermal limits. A centering diameter of 130 mm aligns the flange to machine frames and maintains concentricity. Power and feedback leads exit to the right of the housing so cable trays can be planned on that side. The drive end uses a plain shaft, permitting clamp couplings or friction hubs instead of keyed interfaces and minimizing stress concentrations on the journal.

Additional features support controllability and safety. An integrated brake supplies 11.0 Nm of holding torque, allowing vertical or suspended loads to remain stationary when power is removed. Position information is returned through digital servo feedback, which delivers absolute and incremental data for closed-loop control with high resolution. Motor terminals are realized through a sealed connector, simplifying exchange without rewiring. Vibration is limited by standard balancing, keeping residual imbalance within ISO criteria and reducing bearing load during high-speed operation. The brake and feedback system supports axes that must stop accurately and remain stationary between moves.
