introduction：Frequency changer（Variable-frequency Drive，VFD）Is the application of frequency conversion technology and microelectronics technology，The power control equipment of AC motor is controlled by changing the working power frequency of motor。 The frequency converter is mainly commutated（Ac to DC）、filtering、inverse（Dc to AC）、Brake unit、Driving unit、Detection unit, microprocessing unit, etc。Inverter internalIGBTTo adjust the output power supply voltage and frequency，According to the actual needs of the motor to provide its required power supply voltage，Thus achieving energy saving、Purpose of speed regulation，In addition，The inverter also has many protection functions，Like overflow、overvoltage、Overload protection etc.。With the continuous improvement of industrial automation，Frequency converters have also been widely used。

introduction：Wound rotor motorIn principle, it is equivalent to an ordinary asynchronous motor，There are structural differences，So there are distributed windings on the rotor。If the winding on the rotor is shorted at the collector ring，This motor（In usage）Its just an ordinary cage asynchronous motor。 The use of winding asynchronous motors，It is generally in some occasions that require large starting torque，Like a crane（crane）。Its principle is to change the resistance of the rotor winding，To change the slip rate of the asynchronous motor，To change the torque of the motor。Its stator is directly connected to the three-phase AC power supply，The rotor windings are generally connected in series to a variable resistor with a certain resistance value。When the motor starts，The resistance value of the variable resistor is a large value，After the boot is complete，By adjusting the resistance value，Finally, the resistance value is zero。

introduction：Dc motor governorWorking principle of：The DC governor is the device that regulates the speed of the DC motor，Connect the upper end to the AC power supply，The lower end is connected to the DC motor，The DC governor converts alternating current into two output DC power supplies，All the way to the DC motor to sharpen the magnet（stator），One input to the DC motor armature（rotor），The DC governor adjusts the speed of the DC motor by controlling the armature DC voltage。At the same time, the DC motor gives a feedback current to the governor，The governor judges the speed of the DC motor according to the feedback current，Correct the armature voltage output if necessary，To adjust the speed of the motor again。

introduction：Stepper motorIt is an open-loop control motor that converts the electrical pulse signal into angular displacement or linear displacement，It is the main executive element in modern digital program control system，Extremely widely used。。In the case of non-overload，Speed of motor、The position of the stop depends only on the frequency and number of pulses of the pulse signal，It is not affected by changes in load，When the stepper driver receives a pulse signal，It drives the stepper motor to rotate a fixed Angle in the set direction，call“Step Angle”，Its rotation is carried out step by step at a fixed Angle。The amount of angular displacement can be controlled by controlling the number of pulses，So as to achieve the purpose of accurate positioning；At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency，Thus to achieve the purpose of speed regulation。
