To the question that it was hard to measure and verify the design rationality of the performance parameters for the
ultrasonic cleaning machine, the measuring technology was presented by aluminum foil, and it analyzed feasibility and
an area assessment method for the measurement method by aluminum foil. The corrosion degree of the aluminum foil
was also put forward. It was demonstrated by the experimental study that this measurement method by aluminum foil
could realize the study on the time characteristics of the ultrasonic cleaning machine, selection of the frequency mode of
action and study on the temperature characteristics, which provided an effective data support and experimental
verification for the performance parameters design of the ultrasonic cleaning machine.
The complicate question’s solution of motor winding cleaning need new technologies such as ultrasonic cleaning.
The mechanism of problems that the insulation level of the motor winding would be degraded with time and the motor
winding would resumed tide soon after processing were analyzed. The ultrasonic cleaning method was studies and one
ultrasonic cleaning device was designed. Its safety was verified by the destructive experiment. The test show that this
device can clear away the depositional dirt in the winding thoroughly, which provides a new idea and method to ensure
its insulation level and realize its safe and reliable operation.
