6 Current limitation
Current peak among motor terminals(include instantaneous current peak)should be
below d
emagnetizing current
in order to prevent magnet in motor from demagnetization.
7 Pressure difference between suction and discharge
In all allowable rotational speed range, the difference of pressure should be more than
0.39MPa{4kgf/cm
2
}. But if there is no problem of noise when assembled in air conditioner,
it can also below this value.
