Electrolube’s ER2223 Resin Protects Stator in Next Generation E-Vehicles

Category articles

Electrolube, a global manufacturer of electrochemicals, has developed a solution that protects the stator of a new generation electric vehicle. A high-performance resin material was required to isolate the coil ends of the stator and withstand constant contact with refrigerants. Electrolube performed a series resin tests using various test-specimens that were exposed to oil and cooling fluid for up to +175degC over 168 hours.

The stator in an electric vehicle is the static portion of the engine. It is where electrical energy is supplied by the car’s batteries. The coils produce rotating magnetic fields that pull the conductor rods along the exterior of the rotor when the electric energy from the car’s battery is fed to it. The stator creates a magnetic field which turns the rotor. Electrolube’s ER2223 epoxy resin was chosen for this application due to its outstanding protection against various types of oil and cooling liquids commonly used in today’s automotive industry. ER2223 epoxy potting compound is highly resistant to chemicals and has been designed for harsh automotive applications. It is resistant to all fluids in vehicles’ engine compartments and other mechanical applications. This provides excellent protection for electronic components.

The ER2223 has a wide operating temperature range, from -40degC up to +180degC. This makes it ideal for applications in engine compartments. Because it is low in viscosity, it can be easily plated even the most delicate or tightly packaged components. It also adheres well to many substrates. The ER2223 resin can cure in one hour at 100degC, four hours at 60degC, and 24 hours at room temperatures.

The ER2223 black epoxy resin is a great solution for optimizing the performance of the stator in future-generation electric vehicles. Electrolube is delighted to provide such a reliable solution that protects against chemicals so well. Due to their increased sophistication, EV electronic systems are often more susceptible to contamination and adverse environmental conditions. Because automotive electronic systems are increasingly interconnected, failures in one component can cause the other to fail. Automotive designs, unlike aerospace applications, which may have two or three layers in their systems, must function first time every time throughout the product’s life.
