有刷發電和無刷發電要注意什么?

什么是有刷電機:

What is brush motor?

D88尊龙有刷電機工作時,線圈和換向器旋轉,磁鋼和碳刷不轉,,線圈電流方向的交替變化

D88尊龙When the brush motor works, the coil and commutator rotate, the magnetic steel and the carbon brush do not rotate, and the coil current direction changes alternately.

靠隨電機轉動的換向器和電刷來完成的。

It is accomplished by commutator and brush that rotate with the motor.

什么是無刷電機:

What is brushless motor?

D88尊龙無刷電機由控制器提供不同電流方向的直流電,來達到電機線圈電流方向的交替變換,

D88尊龙The brushless motor provides DC power in different current directions by the controller to achieve alternate transformation of the current direction of the motor coil.

D88尊龙無刷電機的轉子和定子之間沒有電刷和換向器。

D88尊龙Brushless motors have no brushes and commutators between rotor and stator.

D88尊龙無刷電機以電子換向取代機械換向,技術上要優于有刷電機。有刷電機的碳刷易于磨損導致電機的壽命降低。可是無刷電機的效率在一定電流范圍內比有刷電機差。但無刷電機行駛起來幾乎沒有噪聲,且壽命長達10年以上。

Brushless motor is replaced by electronic commutation instead of mechanical commutation, which is superior to brush motor. The brush of brushes motor is easy to wear, resulting in the reduction of the life of the motor. However, the efficiency of brushless motor is worse than that of brush motor in a certain current range. But brushless motors run almost without noise, and their life span is longer than 10 years.

綜合兩者利弊分析,無刷電機還是要優于有刷電機。

D88尊龙Combining the advantages and disadvantages of the two, the brushless motor is superior to the brush motor.

有刷電機和無刷電機的區別是是否配置有常用的電刷-換向器。有刷直流電機的換向一直是通過石墨電刷與安裝在轉子上的環形換向器相接觸來實現的。

The difference between brushless motor and brushless motor is whether there are commonly used brush commutators. The commutation of brushless DC motor is always realized by contacting graphite brush with annular commutator mounted on rotor.

D88尊龙而無刷電機則通過霍爾傳感器把轉子位置反饋回控制電路,使其能夠獲知電機相位換向的準確時間。大多數無刷電機生產商生產的電機都具有三個霍爾效應定位傳感器。由于無刷電機沒有電刷,故也沒有相關接口,因此更干凈,噪聲更小,事實上無需維護,壽命更長。

D88尊龙The brushless motor feedback the rotor position back to the control circuit through the Hall sensor, so that it can get the accurate time of the motor phase commutation. Most of the motors produced by brushless motor manufacturers have three Holzer effect positioning sensors. Since brushless motors have no brushes, they have no interfaces, so they are cleaner, less noisy, virtually maintenance-free, and have a longer life.

D88尊龙近三十年來針對異步電動機變頻調速的研究,歸根到底是在尋找控制異步電動機轉矩的方法,稀土永磁無刷直流電動機必將以其寬調速、小體積、率和穩態轉速誤差小等特點在調速領域顯現優勢。

D88尊龙In the last 30 years, the research on variable frequency speed regulation of asynchronous motor is to find a way to control the torque of asynchronous motor. Rare earth permanent magnet brushless DC motor will show its advantages in the field of speed regulation because of its wide speed regulation, small volume, high efficiency and small steady-state speed error.

D88尊龙無刷直流電機因為具有直流有刷電機的特性,同時也是頻率變化的裝置,所以又名直流變頻,通用名詞為BLDC.無刷直流電機的運轉效率,低速轉矩,轉速精度等都比任何控制技術的變頻器還要好,所以值得業界關注.本產品已經生產超過55kW,可設計到400kW,可以解決產業界節電與高性能驅動的需求。

BLDC brushless DC motor is also known as DC frequency conversion because it has the characteristics of brushless DC motor and frequency variation device. The international common term is BLDC. The operating efficiency, low-speed torque, speed accuracy and so on of BLDC motor are better than any control technology inverter, so it deserves the attention of the industry. This product has been produced. More than 55kW, it can be designed to 400kW, which can solve the demand of power saving and high performance driving in the industry.
