Product Description:

The MDD021B-N-100-N2G-032FB0 is a compact synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as a drive element for digital drive controllers, converting electrical input into precise mechanical rotation for light-duty automation axes, test fixtures, and spindle positioning tasks.

The motor reaches a nominal speed of 10000 min⁻¹, meaning the rotor can turn ten thousand revolutions per minute under rated conditions, which supports short cycle times in handling equipment. During standstill it delivers a continuous torque of 0.30 Nm; this value defines how much load can be held indefinitely without overheating. Rotor position is reported via resolver feedback, a sensor technology that provides absolute angle information with high noise immunity. Power and feedback cabling exit on Side B, so panel designers can place connectors away from moving parts. A centering recess of 32 mm in the flange ensures repeatable concentric alignment with gearboxes or mechanical mounts, reducing radial run-out.

A plain shaft is supplied for backlash-free clamping couplings, and the front end is left without shaft seal, so the installation environment must be dry and dust-free or externally protected. The rotor is held electrically only because the unit ships without a blocking brake; vertical axes therefore need an auxiliary holding device. Internal mass distribution follows standard balancing, allowing operation at the specified speed while keeping vibration within acceptable limits. Connection is made through a circular connector, and the housing length corresponds to code B, simplifying retrofit into existing MDD-series assemblies.
