MDD021A-N-100-N2G-032FA0
The MDD021A-N-100-N2G-032FA0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, it supports precision motion tasks in small automation axes. Its standard housing and standard rotor balancing help keep vibration low while maintaining a minimal footprint. This makes the unit suitable for pick-and-place heads, label applicators, or miniature spindles where space is limited and rapid acceleration is needed.
At its rated electrical frequency, the motor reaches a 10,000 rpm nominal speed, allowing short cycle times for indexing or spindle duties. Continuous torque at standstill is 0.15 Nm, which is the maximum static load the motor can hold thermally without exceeding its temperature limit. A centering shoulder of 32 mm simplifies coaxial alignment with gearboxes or mounting flanges. Power and feedback lines connect through a connector interface, which keeps installation straightforward. Rotor position is measured with resolver feedback, providing analog sine-cosine signals that remain accurate over a wide temperature span and during high rotational speeds. This feedback method also supports stable commutation and speed control with a compatible digital drive.
All electrical connectors are oriented on Side A, so cables can be routed from one face of the machine frame and kept away from adjacent moving parts. The frame code 021 keeps overall motor diameter and inertia low, which benefits lightweight axes that need fast acceleration. A plain shaft transmits torque directly to couplings while minimizing runout that keyed interfaces can introduce. The motor is supplied without a blocking brake, so static holding must be provided by drive torque or an external clamp. The shaft end is present only on the drive side, and the body remains short in length designation A. Because there is no shaft seal, the motor should be installed inside a protected enclosure.
