RESEARCHING AND MANUFACTURING OF NdFeB INTERMEDIATE-FREQUENCY GENERATOR

摘要

A usual Permanent Magnetic (PM) intermediate-frequency generator has a complicated tangential structure PM rotor which is quite expensive and difficult to be manufactured. A new type of one which has the external characteristic similar to a usual one's is made cheaply and simply. The magnetic circuit method and finite element method of 2-D electromagnetic field were used to design the new generator. Many respects was tested to prove that the result is agreed to the designation.
