introduction：Firstly, the two-three-phase motor is analyzedMagnetomotive force harmonics，According to the analysis results, the pole groove fit of the motor and the structure of the motor are determined。Inductance is an important parameter of motor，It is very important in the control and characteristic analysis of motor。This paper analyzes the influence of saturated inductance on the output characteristics of the motor，The partial saturation of the motor is obtained，It is concluded that the current of alternating axis can produce demagnetization on the rotor flux linkage of motor。Because the conventional method can only calculate the inductance value when the inductance is unsaturated，Once the motor is saturated，Conventional methods will not be able to calculate it accurately，This paper is based on finite element simulation softwareFlux，An accurate method for calculating inductance is presented，Based on the permeability of the magnetic circuit，The nonlinear saturation inductance is formulated，The instantaneous inductance

introduction：method/procedure 1、Stepper motor can only be operated by digital signal control，When the pulse is supplied to the driver，In too short a time，The control system is sending out too many pulses，The pulse frequency is too high，The stepper motor will be blocked。To solve this problem，The method of acceleration and deceleration must be adopted。In other words，When the stepper motor starts，To give a gradually increasing pulse frequency，The pulse frequency needs to be gradually reduced during deceleration。Thats what we always talk about“Acceleration and deceleration”method。 2、So when the stepper motor starts at high speed，It is necessary to adopt the method of pulse frequency increase，There should also be a deceleration process when stopping，To ensure the precise positioning control of the stepper motor。Acceleration and deceleration work the same way。
