Product Description:

The MDD021B-N-100-N2K-032MB0 is a compact AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to pair with digital drive controllers, it converts commanded current into precise rotary motion for indexing tables, pick-and-place heads, and other high-speed axes in automated equipment.

This model delivers a continuous standstill torque of 0.30 Nm, giving light mechanisms reliable static holding force with minimal heat rise. A nominal speed of 10000 min⁻¹ supports fast cycle times, while the 32 mm centering diameter simplifies alignment to gearboxes or mounting flanges. Power and feedback conductors exit on Side B, so cabinet wiring can remain consistent when multiple motors share a common orientation. The output shaft is machined with a keyway, allowing direct coupling to pulleys or pinions without additional hubs.

An integrated absolute encoder provides single-turn position data to the controller, and complementary resolver feedback offers robust commutation signals even in electrically noisy environments. Size code 021 and length code B combine for a narrow motor body that fits tight mechanical envelopes. The unit ships without a blocking brake, so designers should integrate an external load-holding mechanism if position retention during power-off is required. Absence of a shaft seal reduces friction and inertia for applications already housed in clean, dry enclosures.

Wake Industrial can arrange same-day shipping for urgent orders, backs each purchase with a 1-year warranty, and keeps quotations valid for 30 days to streamline procurement planning.
