Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The ECM-B3M-E21320RS1 is the servo motor in a Delta motion installation. It converts the drive output into rotary motion and carries the encoder feedback, so the shaft load and the feedback wiring are sized to the ratings stated in the manufacturer documentation, not to a generic assumption.
Typical installations place it in CNC axes, robot arms, feeding and indexing drives, where the unit is matched to the original catalog number and the enclosure provides standard panel or DIN-rail support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
