Symmetrical four-branch wave winding connection method

A method for connecting symmetrical four-branch wave windings include such steps as odd pole pairs of windings, 2n slot per pole per phase, and arbitrary positive integer. The distribution law of eachphase winding is the same. The two phase bands of each phase winding are composed of two parallel branches. The distribution of the two parallel branches is different. By adjusting the coil span of apair of poles, the spans of Symmetrical four-branch wave winding with are 3 * 2 n, 3 * 2 n + 1 and 3 * 2 n- (2n-1) slot spacing; As that invention break the limitation of the traditional AC winding theory, the symmetrical four-branch wave winding connection method is provided for the motor with odd pole number, The contradiction between the capacity, voltage and rotational speed of the large pumped storage motor and the hydro-generator is effectively solved, the performance of the motor is improved, the structure of the motor is reasonable, the manufacturing and installation process is excellent, the maintenance is si
