| Abstract: | The design and the test of a line-start permanent magnet synchronous motor of 2-pole 2.45kW was introduced. The relationship of the tooth flux density and the yoke flux density of the motor was analyzed. A method was presented to control the tooth flux density and the yoke flux density in order to reduce the iron loss and the error, which was demonstrated by test results. The sum of iron loss and mechanical loss of the motor was decreased from 288W to 69W while the corresponding error was reduced from 181.8% to 11.6%. |
