电机用途
1:伺服电动机   伺服电动机广泛应用于各种控制系统中,能将输入的电压信号转换为电机轴上的机械输出量,拖动被控制元件,从而达到控制目的。   伺服电动机有直流和交流之分,最早的伺服电动机是一般的直流电动机,在控制精度不高的情况下,才采用一般的直流电机做伺服电动机。目前的直流伺服电动机从结构上讲,就是小功率的直流电动机,其励磁多采用电枢控制和磁场控制,但通常采用电枢控制。   2:步进电动机   步进电动机主要应用在数控机床制造领域,由于步进电动机不需要A/D转换,能够直接将数字脉冲信号转化成为角位移,所以一直被认为是最理想的数控机床执行元件。   除了在数控机床上的应用,步进电机也可以用在其他的机械上,比如作为自动送料机中的马达,作为通用的软盘驱动器的马达,也可以应用在打印机和绘图仪中。   3:力矩电动机   力矩电动机具有低转速和大力矩的特点。一般在纺织工业中经常使用交流力矩电动机,其工作原理和结构和单相异步电动机的相同。   4:开关磁阻电动机   开关磁阻电动机是一种新型调速电动机,结构极其简单且坚固,成本低,调速性能优异,是传统控制电动机强有力竞争者,具有强大的市场潜力。   5:无刷直流电动机   无刷直流电动机的机械特性和调节特性的线性度好,调速范围广,寿命长,维护方便噪声小,不存在因电刷而引起的一系列问题,所以这种电动机在控制系统中有很大的应用。   6:直流电动机   直流电动机具有调速性能好、起动容易、能够载重起动等优点,所以目前直流电动机的应用仍然很广泛,尤其在可控硅直流电源出现以后。   7:异步电动机   异步电动机具有结构简单,制造、使用和维护方便,运行可靠以及质量较小,成本较低等优点。异步电动机主要广泛应用于驱动机床、水泵、鼓风机、压缩机、起重卷扬设备、矿山机械、轻工机械、农副产品加工机械等大多数工农生产机械以及家用电器和医疗器械等。   在家用电器中应用比较多,例如电扇、电冰箱、空调、吸尘器等。   8:同步电动机   同步电动机主要用于大型机械,如鼓风机、水泵、球磨机、压缩机、轧钢机以及小型、微型仪器设备或者充当控制元件。其中三相同步电动机是其主体。此外,还可以当调相机使用,向电网输送电感性或者电容性无功功率。

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.
