Product Description:

The MDD093A-N-040-N2L-110GL1 is a synchronous servo motor produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated electrical energy into mechanical rotation for positioning or speed-controlled axes in automated machinery. The single-ended plain shaft, internal rotor construction, and integrated feedback components allow direct connection to a matching drive for precise closed-loop motion in packaging, handling, and general industrial equipment. This arrangement supports accurate speed regulation and repeatable axis response during start, stop, and dwell cycles.

Under continuous stall conditions, the motor can supply 9.2 Nm of torque, helping the drive maintain holding force without unnecessary current limiting. Its nominal operating speed is 4000 rpm, enabling high peripheral velocities on compact linear stages or spindle heads. A blocking brake rated for 11 Nm is built in, and this spring-applied device secures the axis against back-driving when power is removed. This is useful on vertical or suspended loads that must remain stationary during power loss. Position data are returned through digital servo feedback, giving the controller rotor position data for loop closure and electronic commutation. Mechanical alignment to adjacent components is guided by a centering diameter of 110 mm, which supports an accurate pilot fit at the front flange.

The power and feedback leads exit on the left side because the connection hardware is a keyed circular connector fixed in that orientation, which can simplify cable routing in multi-axis cabinets. Contaminants are kept out of the bearing cavity by a shaft seal, allowing the standard housing to maintain its sealing performance when mounted to gearboxes or couplings. The rotor uses a plain shaft, avoiding keyway stress concentrations and supporting shrink-fit transmission elements. With a frame size code of 093, the motor balances moderate inertia with the shorter A-length variant, which helps support responsive acceleration while preserving a compact installation footprint. The connector position can also help keep bending stress away from nearby moving machine elements.
