introduction：Analysis transformerThe relationship between the various electromagnetic quantities，The positive direction of each quantity must be specified，Then list the equation。The positive direction is arbitrarily specified，Different positive direction，The equation is different，But the result remains the same。therefore，In the case of stepper motor acceleration，The positive direction is specified according to the feed example，That is, the current of the stepper motor in the primary windingflStepper motor voltage by power supplyv1produce，Stepper motor current in secondary windingJ2Induced electromotive force by the secondary winding straightzproduce。The current of the stepper motor in the winding and its generated flux It fits the right hand spiral relationship，The magnetic flux and the electromotive force induced in the winding conform to the right hand helix relationship。 In a single phase transformer，The voltage of the stepper motor in the primary winding is equivalent to the voltage of the no-load stepper motor in

introduction：Dc motorThe structure should be composed of two parts: the stator and the rotor。The stationary part of a DC motor is called the stator，The main function of the stator is to generate a magnetic field，Following stand、Main pole、Commutating pole、End cover、Bearing and brush device, etc。The part that turns during operation is called the rotor，Its main function is to produce electromagnetic torque and induced electromotive force，It is the hub of DC motor for energy conversion，So its often called an armature，Driven shaft、The armature core、Armature winding、Commutator and fan, etc。 I believe everyone is using it24VDC motors sometimes encounter the phenomenon of noise，Affect the operators operating emotions，What should be done about this phenomenon，This is a headache for many manufacturers，Here is a brief introduction for you24Noise treatment of VDC motors： 1、Transmission component damage The transmission component is damaged due to improper operation during installation，The system movement is inaccurate or unstabl

introduction：Rodless cylinder life Rodless cylinder refers to the use of pistons directly or indirectly connected to the external actuator，And make it follow the piston to achieve reciprocating movement of the cylinder，Thus achieving transmission。Each transmission component has its own life，The life of a component is determined by many factors。Maintenance plays a key role in the life of a component，Whether the maintenance is good or not can determine the life span of a part. The following Feng Ye Xiaobian will take you to understand the maintenance of rodless cylinders。

introduction：Ac motorSoft start（soft starting of ACmotor）The starting process of an electric motor is divided into two stages，The first stage is slope starting，Then the constant current starting stage.The starting current is automatically reduced when the starting is about to end。Starting current rise rate and constant current value can be set arbitrarily，Constant current value melon size determines the length of starting time。therefore，The rising rate of starting current and the constant current value should generally be set according to the load and production requirements，To make the soft starter get the best starting process，And reduce the starting loss。 Current characteristics of slope constant current soft starting Slope constant current soft starting is generally suitable for no-load or light load starting，It is also suitable for load equipment whose starting torque increases with the increase of speed，Like ventilator、Water pump。
