Product Description:

Bosch Rexroth Indramat manufactures the MDD093A-N-040-N2M-130GA0 in the MDD Synchronous Motors series. The unit is a motor for digital drive controllers that supplies controlled torque and speed to automated axes in packaging lines, pick-and-place modules, and light machining centers. Its compact stator and internal rotor convert drive current into mechanical rotation while exchanging position information with the associated controller. It is intended for servo applications in which the drive controller regulates current continuously rather than using open-loop operation. That operating method helps the motor respond quickly to command changes and load variation during indexing, feeding, and transfer moves.

A centering diameter of 130 mm aligns the flange for accurate mounting on the machine. The power and feedback conductors exit on Side A, and the Connector interface keeps the electrical connection compact. The rotor is balanced to a standard grade to limit vibration when the housing is fixed to the machine frame. During continuous stall conditions, the motor can deliver 9.2 Nm of torque, and the windings support a nominal speed of 4000 rpm for fast positioning cycles. The unit is supplied without a blocking brake, so any load that must remain fixed with power removed needs external holding. Cable routing from one side can also simplify layouts in compact machine sections.

Position data are transmitted through Digital servo feedback (DSF), which works with the drive to provide precise closed-loop control. The integrated multiturn absolute encoder retains position information across multiple revolutions, which supports immediate position reference after startup. Because feedback is integrated, no separate external measuring device is required for standard closed-loop operation. The motor uses a plain shaft with a radial shaft seal, allowing direct coupling to pulleys or couplings while helping limit contaminant entry at the shaft opening. There is no shaft extension on side B, which keeps the non-drive end compact and leaves the main output interface on the drive side.
