Product Description:

The MDD093A-N-040-N2M-130PB2 is an AC synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts electrical energy into controlled rotary motion for positioning axes, gantries, or packaging equipment in automated plants. Its standardized housing and balancing grade match the dynamic requirements of mid-range servo applications, and the coordinated mechanical interface, electrical terminations, and feedback device allow straightforward integration into automated systems. This motor is suited for applications that need repeatable speed control and accurate position response during frequent starts, stops, and direction changes.

The motor’s flange includes a centering bore of 130 mm. This dimension aligns the stator precisely on the machine frame and helps minimize radial runout during high-speed operation. Power and feedback conductors exit on Side B, a layout that keeps cabling clear of the driven load when the shaft points forward. Under continuous stall conditions, the winding can deliver 9.2 Nm of torque, providing stable force even when the axis is held motionless. Position data are captured by an integrated multiturn absolute encoder, which records revolutions without battery support and sends them to the controller so startup can occur without a homing cycle. During motion, the rotor can reach a nominal velocity of 4000 min⁻¹, matching applications that need fast indexing with low-inertia components.

For static safety, a blocking brake rated at 22 Nm engages automatically when power is removed, holding vertical or suspended axes without additional clamps. The feedback channel uses Digital servo feedback, enabling high-resolution velocity loops and simplified signal handling between the motor and drive. Mechanical power is transmitted through a keyway shaft, a form that mates with standard coupling hubs and helps prevent slip under peak load. Contaminants are kept out by a dedicated shaft seal, which helps protect internal bearing areas during operation in typical industrial environments. The motor layout supports stable axis behavior during repeated motion cycles, and the enclosed feedback and shaft interface reduce the need for auxiliary external components.
