the servo motor, servo motor is widely used in various kinds of control system, can convert the input voltage signal on the shaft of motor controller mechanical output, drag the control element, so as to achieve the control purpose. With dc and ac servo motor, the original servo motor was general of dc motor, the control accuracy is not high, only the general controller of dc motor servo motor. Structurally, the dc servo motor is small power dc motor, its excitation controlled by the armature and field control, but usually the armature control. Stepper motor: mainly used in the field of nc machine tool manufacturing, due to the stepper motor don't need A/D conversion, can be directly to digital pulse signal into angular displacement, therefore has long been regarded as the most ideal CNC machine actuators. In addition to the application of nc machine tools, step motor controller can also be used in other machinery, such as automatic feeder of the motor, as a general purpose of the floppy disk drive motor, can also be applied in the printer and plotter. Torque motor, torque motor has the characteristics of low speed and large torque. Generally in the textile industry often use ac torque motor, its working principle and structure of single-phase asynchronous motor and the same. Brushless dc motor, brushless dc motor of the mechanical properties and the characteristics of the adjustment good linearity, wide speed range, long service life, convenient maintenance noise small, does not exist a series of problems caused by brush, so this kind of motor in the control system has a lot of applications. Dc motor, dc motor has good speed regulation performance and the advantages of starting easily, can load starting, so the direct current motor is still widely used, especially in the coming of SCR dc power. Asynchronous motor, asynchronous motor has simple structure, manufacture, use and maintenance is convenient, reliable operation and the quality is small, low cost advantages. Asynchronous motor is widely used as the drive machine, water pump, fan, compressor, lifting lifting equipment, mining machinery, light industrial machinery, agricultural and sideline products processing machinery, etc. Most of the workers and peasants production machinery, household appliances and medical devices, etc. Used in household appliances, such as electric fans, refrigerators, air conditioners, vacuum cleaners, etc. Gear motor controller: refers to the speed reducer gear motor controller and motor controller ( The motor) The integration of the body. This integration can also often called the body geared motor or gear motor controller. How selection: motor controller parameters: get to know the specifications of the motor controller, functional characteristics, protective type, rated voltage, rated current, rated power, power frequency, insulation class, etc. These contents can provide referential basis for the correct selection protector to users. Environmental conditions: refers to the normal temperature, high temperature, cold, corrosion, vibration degrees, such as sand, altitude, electromagnetic pollution motor controller USES: mainly refers to drag the machinery and equipment requirements, such as fan, water pump, air compressor, car bed, different load mechanical properties such as oil field pumping units. Control mode: control mode with manual, automatic, local control, remote control, independent single line, production line of centralized control, and so on and so forth. Have a direct, step-down startup mode, star Angle, frequency sensitive rheostat, frequency conversion device, soft start, etc. Other aspects: the user production monitoring management situation on the spot, the sex of the severity of the impact on production downtime, etc
