IRMCF341 application on frequency conversion electrical appliances

 IRMCF341 application on frequency conversion electrical appliances, mainly aim at high functionality and save electricity. For example, requires higher than that of high speed, good control performance and www.facebook.com/dongfeng.motor small size light weight, large capacity, high comfort, long life, safe and reliable, mute, save electricity, etc. 341 is mainly used in permanent magnet synchronous motor, ac permanent magnet synchronous motor is a kind of can directly start up in the 50 hz three-phase alternating current environment of electric motor, its operation mode is: start asynchronous, synchronous operation. 

Ac permanent magnet synchronous generator set spare parts motor is rare earth permanent magnet materials to replace traditional electrical excitation and made of high efficiency and energy saving motor, it not only has general and permanent magnet motor has simple structure, reliable operation, the advantages of small fever, but also has small volume, light weight, low loss and high efficiency of marked characteristics, can realize the traditional electro-magnetic motor is 3 phase induction motor difficult to achieve high performance. Plus 341 based on FOC () field oriented vector frequency conversion control, sine wave driving mode for 180 degrees, more make it fully play at the same time, the performance of 341 USES electric resistance current sampling refactoring techniques, save the cost and single resistance current sampling reconstruction technology refers to the current 341 use current PWM corresponding state, use appropriate delay time (avoid current oscillation) can collect the real bus current, will to many times current restructuring in the PWM timing can be three phase current.
