Abstract
The main and collector terminal studs of a dynamoelectric machine are coated with a powder resin to form an electrical insulator between the rotor and the stud. The collector terminal stud includes a gasket which is compressed against the powder coating on the stud to form a seal with the powder coating preventing leakage of hydrogen gas through the seal. A fluidized bed containing the resin powder disperses the powder in a mist. By charging the powder, an electrostatic potential is provided between the stud and charged powder whereby the powder adheres to the stud. Alternatively, the stud will be preheated and dipped into a bed of powder whereby the powder adheres to the stud. The powder resin is subsequently cured.
