6 Current limitation
Current peak among motor terminals（include instantaneous current peak）should be
below demagnetizing 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
2
0.39MPa{4kgf/cm
}. But if there is no problem of noise when assembled in air conditioner,
it can also below this value.
