Product Description:

The MDD090A-N-020-N2L-110PR1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded electrical output from the drive into mechanical rotation for positioning tasks, conveying elements, or indexing stations in automated equipment. Standard balancing and housing features support direct machine mounting, while the built-in blocking brake keeps axes stationary when power is removed, making the unit suitable for vertically oriented loads in packaging, printing, and material-handling lines.

The motor seats against a register that measures 110 mm in diameter, ensuring precise concentricity with gearboxes or flange adapters. During static operation, it delivers a continuous holding capability of 3.7 Nm, allowing tight position control without overheating. Under rated excitation, it reaches a nominal speed of 2000 rpm, matching drive controllers used in typical industrial motion systems. When deceleration or gravity attempts to back-drive the axis, the integrated brake applies up to 6.5 Nm of countertorque to prevent motion. Rotor position is reported through digital servo feedback, which supplies high-resolution signals to the controller for fine velocity and torque loops. Power is transferred through a shaft that features a keyway, simplifying rigid coupling to pulleys, pinions, or flexible couplings without relying on friction alone.

All electrical and feedback connectors are oriented on the right side of the frame so cabling can follow machine layout without tight bends. Length code A designates the shortest stack in the 090 family, reducing mass and moment of inertia while still using the same 110 mm centering pilot. A built-in shaft seal protects the bearing set from coolant splash and dust, and the standard shaft end omits an extension on side B to maintain compact depth.
