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
