Product Description:

The MDD021B-N-100-N2G-032FA0 is a compact AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, it generates controlled rotary motion for pick-and-place heads, feed mechanisms, and other precision axes in automated equipment. The unit uses size code 021 and length code B, giving it a short stator that fits tight machine spaces without adding unnecessary bulk. Its compact format is suitable for small moving assemblies where low mass and precise response are important during repeated positioning cycles.

It delivers a nominal shaft speed of 10,000 rpm, allowing rapid duty cycles in small assemblies. At standstill, the electromagnetic circuit sustains 0.30 Nm of continuous torque so light loads can remain stationary without additional braking. Accurate mechanical alignment is supported by a 32 mm centering diameter that seats the flange to the machine face. Power and feedback leads exit on Side A, which can simplify cable routing in compact layouts, and rotor position is tracked through resolver feedback that tolerates high temperatures and electrical noise. This feedback method supports stable commutation and consistent speed control across a wide operating range.

Connection to the cabinet harness is made through a molded connector, avoiding the need for hard-wired terminals. The motor is supplied without a blocking brake, so static holding force must be provided by the drive or an external device when the axis is stopped. Its mechanical interface uses a plain shaft machined to ISO tolerances, and it is delivered without a shaft seal, which helps reduce friction in clean, dry installations. A standard housing encloses the windings, and the motor uses only one shaft end so the overall length remains compact for installation in tightly spaced machinery.
