Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-040-N2M-110GA2 as part of the MDD Synchronous Motors series. Intended for digital drive controllers, this synchronous AC motor converts electrical commands into controlled rotation for positioning tables, feeders, and pick-and-place axes in automated lines. The motor uses the 090 frame, carries the B length code, and comes in a standard housing that fits existing Rexroth mounting kits used on compact servo axes.

Key performance limits describe how the motor behaves under load. At standstill it can deliver 7.2 Nm, so fixtures can be held without overheating when motion is paused. During normal operation the rotor reaches 4000 rpm, a speed that matches high-throughput servo axes driven by 8 kHz current loops. The integrated blocking brake supplies 11.0 Nm of static torque to prevent drift once power is removed. A centering shoulder of 110 mm ensures concentric alignment to gearboxes or flanges, which helps reduce radial runout. Position data are returned through digital servo feedback (DSF), allowing the drive to read multi-turn absolute information from the embedded encoder and close the loop without additional measuring systems.

Mechanical interfaces support quick installation. Power and feedback leads exit on Side A, and factory-fitted Connector terminations eliminate hard wiring inside the cabinet. Keeping both electrical connections on one end can simplify cable routing in compact machine layouts. A plain shaft with a shaft seal prevents lubricant leakage while still allowing direct coupling. The model omits a side-B shaft end to save space near adjacent components or guards. Standard balancing limits residual vibration to levels appropriate for bearing service life. The housing has a standard finish, and the motor has no pole-face modifications.
