Stepper motor two-phase stepper motor in the process of use is need to pay attention to some matters needing attention, so what are the considerations the stepper motor, there are 'LiWei, professional technicians and simple to give everybody said: step 1, step motor, had better not use the whole state, the state step vibration. 2, due to historical reasons, only a nominal for the 12 v voltage of motor using 12 v, the other motor voltage value is not driving voltage v, can choose according to drive the driving voltage. 3, big moment of inertia of the load should choose motor frame size larger. 4, the motor in the high speed and large inertia loads, generally not starting in her work, and use frequency speed gradually rise, a step motor do not break, two can reduce noise can improve the positioning accuracy of stop at the same time. 5, high precision, through mechanical speed, increase the speed of the motor, and fine fraction is high drive to solve, also can use 5 phase motor. 6 work under 90 RPM, motor, small current should be adopted, large inductance and low voltage to drive. 7, motor should not work in vibration zone, if must be by changing the voltage, current, or add some damping.
