【 Introduction 】 brushless dc motor in the south of anhui : careful web will find, when we go to see some of the refrigerator, air conditioner and washing machine products, can be seen in the title with & other; Frequency conversion & throughout; This keyword. Here, of course, frequency conversion is the product of frequency conversion brushless dc motor, then compared to before we used this kind of electrical appliances product in terms of brushless dc motor, what are some of the characteristics of frequency conversion brushless dc motor? What special experience can bring us again? Let us explore together. Compared with the traditional brushless dc motor frequency conversion brushless dc motor what is the advantage? “ Frequency conversion & throughout; Everywhere; Compared with the traditional brushless dc motor frequency conversion brushless dc motor what is the advantage? Manufacturer of propaganda about frequency conversion brushless dc motor: & middot; More energy efficient operation of all electrical appliances in the brushless dc motor, all have different degrees of harmonic voltage and current, make the motor in non-sinusoidal voltage, power flow operation. Can lead to higher harmonic motor stator copper loss, rotor copper ( Aluminum) Consumption, iron loss and the increase of the additional loss, the most significant is the rotor copper ( Aluminum) Consumption. Because ordinary ac asynchronous motor is close to the base wave frequency corresponds to the synchronous speed of rotation, therefore, higher harmonic voltage to a larger slip cutting rotor after conducting bar, will produce very big rotor loss. In addition, also should be considered because of skin effect produced by the additional copper loss. These losses will make motor extra heat, low efficiency, output power is reduced, but if you use the frequency conversion brushless dc motor, the energy consumption can reduce 20% About 30%. · Long life brushless dc motor at run time is about several thousand to more than 10 KHZ carrier frequency, which makes the motor stator winding to withstand high voltage build-up rate, equivalent to impose great impulse voltage gradient on motor, the motor of the turn-to-turn insulation withstand ordeal. And frequency conversion brushless dc motor can work under the voltage of the rectifier filter under performance can be more stable, and longer service life. · Small ordinary asynchronous motor due to electromagnetic noise, machinery, ventilation and other factors caused by the vibration and noise becomes more complicated. Frequency conversion power harmonic and motor electromagnetic part contains all of the time the inherent space harmonic interference each other and form all kinds of electromagnetic vibration force. When the electromagnetic wave frequency and motor of the body's natural vibration frequency is consistent or close to, will produce resonance phenomenon, so as to increase the noise. Due to the motor operating frequency range wide, wide speed change range, all kinds of the electromagnetic wave frequency is difficult to avoid the components of the motor of the inherent vibration frequency. But the frequency conversion brushless dc motor can effectively solve these problems. This article is from the China net brushless dc motor.
