Abstract

Disclosed in the present invention is a stepping motor drive power supply circuit, comprising a power supply circuit connected to an adapter. The power supply circuit is connected to a voltage switching circuit used for switching and outputting different voltages; the voltage switching circuit is connected to a five-wire four-phase motor connection circuit, a four-wire two-phase motor connection circuit, a three-wire motor with driver connection circuit, and a main control circuit used for controlling the voltage switching circuit to switch and output voltages and separately outputting motor drive signals to the five-wire four-phase motor connection circuit, the four-wire two-phase motor connection circuit, and the three-wire motor with driver connection circuit; and the main control circuit is connected to a key circuit used for setting drive power supply characteristic parameters and inputting a control instruction, and a display circuit used for displaying the drive power supply characteristic parameters and a motor working state. The function of rapidly switching on site by using the same device for detecting the performance of different types of small-power stepping motors is achieved.
