EVMS/EVMSL
*5 In the case of inverter drive, be careful of the following points, and discuss the situation with the
manufacturer of the inverter used.
Ensure that the motor's operating output is 90% or less of the rated output.
(1)
(2) Set the output frequency range at 60 to 95% of the mains power frequency.
(3) With inverter drive, magneto-sonic waves are produced by the motor, which may sound
quite harsh in comparison with mains power drive.
(4) Avoid a rotational speed range in which the pump and motor resonate during normal
operation.
*6 0.75 kW or higher models is cleared the Top Runner Standards.
*7 0.55 kW or less models is equivalent to premium efficiency (EBARA own setting).
