      電機用途
      1:伺服電動機   伺服電動機廣泛應用于各種控制系統中,能將輸入的電壓信號轉換為電機軸上的機械輸出量,拖動被控制元件,從而達到控制目的。   伺服電動機有直流和交流之分,最早的伺服電動機是一般的直流電動機,在控制精度不高的情況。才采用一般的直流電機做伺服電動機。目前的直流伺服電動機從結構上講,就是小功率的直流電動機,其勵磁多采用電樞控制和磁場控制,但通常采用電樞控制。   2:步進電動機   步進電動機主要應用在數控機床制造領域,由于步進電動機不需要A/D轉換,能夠直接將數字脈沖信n轉化成為角位移,所以一直被認為是最理想的數控機床執行元件。   除了在數控機床上的應用,步進電機也可以用在其他的機械上,比如作為自動送料機中的馬達,作為通用的軟盤驅動器的馬達,也可以應用在打印機和繪圖儀中。   3:力矩電動機   力矩電動機具有低轉速和大力n的特點。一般在紡織工業中經常使用交流力矩電動機,其工作原理和結構和單相異步電動機的相同。   4:開關磁阻電動機   開關磁阻電動機是一種新型調速電動機,結構極其簡單且堅固,成本低,調速性能優異,是傳統控制電動機強有力競爭者,具有強大的市場潛力。   5:無刷直流電動機   無刷直流電動機的機械特性和調節特性的線性度好,調速范圍廣,壽命長,維護方便噪聲小,不存在因電刷而引起的一系列問題,所以這種電動機在控制系統中有很大的應用。   6:直流電動機   直流電動機具有調速性能好、起動容易、能夠載重起動等優點,所以目⒅繃韉綞機的應用仍然很廣泛,尤其在可控硅直流電源出現以后。   7:異步電動機   異步電動機具有結構簡單,制造、使用和維護方便,運行可靠以及質量較小,成本較低等優點。異步電動機主要廣泛應用于驅動機床、水泵、鼓風機、壓縮機、起重卷揚設備、礦山機械、輕工機械、農副產品加工機械等大多數工農生產機械以及家用電器和醫療器械等。   在家用電器中應用比較多,例如電扇、電冰箱、空調、吸塵器等。   8:同步電動機   同步電動機主要用于大型機械,如鼓風機、水泵、球磨機、壓縮機、軋鋼機以及小型、微型儀器設備或者充當控制元件。⒅腥相同步電動機是其主體。此外,還可以當調相機使用,向電網輸送電感性或者電容性無功功率。

      1: servo motor servo motor is widely used in various control systems, can be input voltage signal is converted to a motor shaft mechanical output, drag the control element, so as to achieve the purpose of control. Servo motor with AC and DC component, the first servo motor is a general DC motor, the control precision is not high, the use of general DC motor servo motor. The present DC servo motor structurally, small power DC motor, the excitation by armature control and field control, but usually the armature control. 2: stepper motor stepper motor is mainly used in NC machine tool manufacturing field, the stepping motor does not require A / D conversion, can be directly digital pulse signals into angular displacement, so it has been considered to be the most ideal NC machine tool components. In addition to the application of NC machine tool, the stepper motor can also be used on other machines, such as automatic feeding machine motor, as universal floppy drive motor, but also can be used in printers and plotters. 3: torque motor torque motor with low speed and high torque characteristics. General in the textile industry often use AC torque motor, the working principle and structure and single phase asynchronous motor with the same. 4: Switched Reluctance Motor SRM switched reluctance motor is a new type of motor, the structure is extremely simple and rugged, low cost, speed control performance, is the traditional motor control strong competitor, has great market potential. 5: brushless DC motor brushless DC motor mechanical characteristic and regulation characteristics of good linearity, wide speed range, long service life, convenient maintenance and low noise, not because of the brush and causes a series of problems, so the motor in the control system has great application. 6: DC motor has good speed, easy to start, to load the advantages of starting, so now the application of DC motor is still widespread, especially in the SCR after DC power supply. 7: asynchronous motor asynchronous motor has the advantages of simple structure, convenient manufacture, use and maintenance, quality and reliable operation of small, low cost. Induction motors are widely used in driving machine, water pump, blower, compressor, lifting hoisting equipment, mining machinery, light industrial machinery, agricultural and sideline products processing machinery production machinery as well as most workers and peasants household appliances and medical equipment etc.. In the household appliances more applications, such as fans, refrigerators, air-conditioning, such as vacuum cleaners. 8: synchronous motor synchronous motor mainly used for large-scale machinery, such as blowers, pumps, compressors, ball mill, rolling mill as well as small, miniature equipment or a control element. One phase of a three-phase synchronous motor is the main. In addition, still can be adjustable camera use, to the grid inductive or capacitive reactive power.
