| Abstract: | Water abrasion of the rotor in waterfilled submersible motor takes majority of mechanical loss of the motor. However, there is not a simple and practical method to calculate the water abrasion. Based on theoretical analysis and a large number of experiments, the main factors affecting water abrasion of the rotor were studied, and the calculation method for water abrasion of the rotor was proposed. This method was verified and employed in practical design and production. |
