The motors are tested in accordance with IEC 34-1, 1969.
The stator is insulated in accordance with class F (310º F, 155º C). The motor is designed
to deliver its rated output at ± 5% variation from the rated voltage. Without overheating
the motor, ± 10% variation from the rated voltage can be accepted provided that the
motor does not run continuously at full load. The motor is designed to operate at a
voltage imbalance of up to 2% between the phases.
Monitoring Equipment
The stator incorporates thermal contacts connected in series.
The pump can be equipped with sensors for sensing water in the stator housing.
