Effect of Laminated Core Body Size on Motor Magnetic Properties

چکیده
The magnetic characteristics of electromagnetic steel sheets used for motors are evaluated under ideal sinusoidal excitation. However, in actual equipment driving, excitation by pulse-width modulation (PWM) waves is the mainstream method. Therefore, it necessary to clarify how properties changed and inverter To laminated core excitation, samples with different sizes were prepared effects on then investigated. measured changing only input voltage VDC while maintaining carrier frequency factor constant. As results, iron loss values small, medium, large 6.05, 9.58, 11.62 W/kg, respectively. losses toroidal cores increased 124.9, 256.1, 332.0%, respectively, compared each larger body, higher required loss. It can be inferred that a amount energy was excite core. This because change flux density per unit time greater than other cores. indicates generated eddy currents possible say generate current

15 صفحه اولSmart Starting of Induction Motor by Changing Core Magnetic Flux Value
Single-phase squirrel cage and three-phase induction electromotors are the most popular electromotors used in industry from long ago. When an induction motor starts with direct connection method, it takes a lot of current from the power supply (several times the nominal current); so, several methods have been devised to start such electromotors. These methods either reduce the voltage of the st...
