Product Description:

The MDD093A-N-040-N2M-110GR2 is a synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Intended for digital drive controllers in industrial automation, the unit converts regulated current into rotary motion for indexing tables, pick-and-place axes, and similar closed-loop positioning tasks. Its standard housing eases cabinet integration, and a factory balancing grade keeps vibration within permissible limits during high-speed operation.

At the mechanical level, the rotor is dynamically balanced to the manufacturer’s standard grade, and the shaft terminates in a plain shaft so couplings can be mounted directly. The centering spigot measures 110 mm, providing a precise fit against gearboxes or machine frames. Electrical terminations are handled through a sealed connector oriented to the right, a layout that keeps cables clear of moving assemblies. The motor delivers a continuous standstill torque of 9.2 Nm and can accelerate loads to its nominal speed of 4000 rpm without exceeding thermal limits. Position retention during power-off is handled by a blocking brake that applies 22 Nm of holding torque. A standard housing encloses the windings, and the absence of a secondary shaft end on side B reduces overall length while retaining IP integrity.

The feedback system is an integrated multi-turn absolute encoder that tracks shaft angle over multiple revolutions, and its signals are transmitted as digital servo feedback (DSF) to the drive controller for closed-loop regulation. A shaft seal is installed at the outlet to protect internal bearings; this lip seal is specified as with a shaft seal to confirm the barrier against coolant or dust ingress. The compact A-length construction, identified by motor length code A, joins the 093 frame size to keep mass low while preserving magnetic torque density.
