Abstract

The utility model relates to a daughter circuit board for conversion of interface signals of an electronic commutation motor. For the connection between the daughter circuit board and a user terminal controlling system, eight ports are arranged, namely five switching signal input ports (M1, M2, M3, M4 and M5), a PWM (Pulse Width Modulation) port, a port G2 and an R/T port, wherein the voltage of the five switching signal input ports is AV voltage within the range of 10V-24V, and the current is smaller than 4 mA; for the PMW signal port, motor rotation speed/torque control command signals are input, the input signals are pulse signals with frequency of 80 Hz-100Hz, and the voltage ranges from 14V-35V; the port G2 is a common terminal of switching signals; and the R/T port is a half-duplex bidirectional asynchronous communication data line serving as a port for data transmission between the daughter circuit board and the user terminal control system. The ports of the daughter circuit board adopt novel electric codes, are relatively simple, facilitate the signal matching with the user terminal controlling system of a client, form a relatively-universal standard and facilitate the management, popularization and application.
