Ⅳ. Difference Between a Water Pump Motor Stator Tester and a Water Pump Coil High-Voltage Tester：

Many companies refer to a water pump motor stator tester as a water pump coil high-voltage tester.

The standard test items for a water pump coil high-voltage tester include resistance, AC hi-pot , insulation, turn-to-turn ratio, direction of rotation, and inductance.

A water pump coil high-voltage tester is a device used to test the coils of a water pump, specifically to determine if the coils can withstand high voltage. In a water pump motor, the coil is a crucial component; the coil, commonly known as the motor stator, is typically made of conductive material and is used to generate a magnetic field to drive the pump.

A water pump coil high-voltage tester applies a high-voltage current to the coil to simulate the voltage load it needs to withstand during actual operation. This test evaluates the coil's insulation performance and withstand voltage capability, ensuring its safety and reliability under operating conditions.
