Notes

This revision replaces and cancel the previous one, which
must be eliminated.
(1) Looking the motor from the shaft end.
(2) Measured at 1m and with tolerance of +3dB(A).
(3) Approximate weight subject to changes after
manufacturing process.
(4) At 100% of full load.

These are average values based on tests with sinusoidal
power supply, subject to the tolerances stipulated in NEMA
MG-1.
