The 220V 60Hz three-phase electric motor is a genuine IMER OEM part, part number 3228123, for the IMER Masonry 750 Plus saw. The IMER parts book lists it as the motor, ref. 91, in Table 2 (Machine Structure), with the note "220 v60 hz TPH".

The same reference lists other motor codes for other power supplies, including 3230330 for 220V 60Hz SPH. This is the 220V, 60Hz, three-phase version, so confirm that your saw runs on that power supply before ordering.
