The performance analysis and calculation for variable frequency speed control motors with the rotor structure optimized

摘要

In the paper, the method to optimize the rotor structure in variable frequency speed control motors is introduced. The saturation and the skin effect are considered and 2D no-load and load electromagnetic field is calculated in finite elements for a variable frequency speed control motor before and after optimization. Finally,no-load current and operation performance before and after optimization are obtained and the two results are contrasted.
