Spodaj kot uvod v štiri prednosti krmilnika DC brez krtača, naj bodo vsi krmilnik brezkrtačnega DC motorja jasnejše razumevanje.
1, the brushless dc motor controller because has the characteristics of a dc motor controller, also drives the frequency change device, so also known as dc converter, dc brushless motor controller operation efficiency, and low speed torque and rotational speed precision and so on is more good than any of the control technology of inverter, the brushless dc motor based on automatic control type to perform, so not as frequency control of motor speed under overloading starting of synchronous Motorni krmilnik kot plus zagonsko navijanje na rotorju, prav tako ne bo ustvaril nihanja in odstopil pri mutaciji obremenitve.
2, Trajni magnetni krmilnik DC brez krtača, zdaj redek zemeljski material NDFEB z uporabo visoke magnetne energije. Kot rezultat, količina redkega zemeljskega trajnega magnetnega motorja brez krtače kot trifazni asinhroni motor z zmogljivostjo zmanjšuje število okvirja.
3, brushless dc motor controller of high efficiency, high efficiency area is big, the power and torque density, high power factor (COSΦ)Close to 1, the system efficiency> 90%, the permanent magnet brushless dc motor controller in any case the rotor are synchronous operation, ac variable frequency motor is frequency control of motor speed controller, is the speed regulation of frequency conversion brushless dc motor controller, motor Krmilnik, ki deluje pod sinhrono hitrostjo, rotor nima ne izgube bakra in izgube železa.
4, brezkrtačni DC krmilnik motorja ima dobre nizko napetostne značilnosti, značilnost preobremenitve navora je močna, velik zagonski navor, majhen zagonski tok itd.
