Simulating use and Aging of Immersive Coolants for Electric Motors: 11,169,104

Abstract: 

A system for simulating the effects of use and aging on immersive coolants. Two conductive coils are immersed in a tank containing a sample of the coolant. The coils are spaced such that electrical activation of the first coil induces current in the second coil. A DC power source is provided to an inverter, which provides AC current for activating the first coil. The induced AC current in the second coil is delivered to a rectifier which converts the induced AC current to DC current. The DC current is then returned to the power source. The electromagnetic field between the coils simulates motor operation, so that the coolant's physical and chemical characteristics can be tested for the effects of use and aging.
