MDD021B-N-100-N2K-032FA0 Bosch Rexroth Indramat

Product Description:

The MDD021B-N-100-N2K-032FA0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified by the manufacturer as a motor for digital drive controllers, it supplies compact rotary power for high-speed positioning tasks in automated machinery. The small 021 frame and B length allow integration on lightweight axes, and its electronic interface is intended to pair directly with Indramat drives for closed-loop control in pick-and-place heads, feeders, and similar equipment.

At standstill the motor delivers 0.30 Nm of continuous torque, enough to hold loads while the drive maintains field orientation. Once energized it reaches a nominal velocity of 10000 min⁻¹, so short travel cycles can be executed without mechanical gearing. Mounting is centered by a 32 mm pilot, and the rotor is trimmed to standard dynamic balance to keep vibration within servo tolerances. Electrical and feedback leads exit on Side A, and a sealed circular connector provides quick interchange during service. Position data are returned through Resolver feedback, giving analog sine-cosine signals that are tolerant of electrical noise common on compact machinery. Its standard aluminum housing acts as the primary heat sink.

The mechanical interface follows a Plain shaft layout, eliminating keyways and allowing friction-fit couplings on miniature gearboxes. An Integrated absolute encoder shares the motor’s shaft, supplying multiturn position information so homing routines are unnecessary after power cycling. For braking, the assembly ships without a blocking brake; any holding force must be supplied by the drive or external clamps. It is also delivered without a shaft seal, an arrangement that minimizes friction but restricts use to dry, protected enclosures; the standard shaft end on side A completes the mounting envelope.
