High-accuracy motor test system based on triode trigger circuit

The invention discloses a high-accuracy motor test system based on a triode trigger circuit. The high-accuracy motor test system is composed of a single-chip microcomputer (1), a power supply module (2), a motor speed control module (3) and a display (7) connected with the single-chip microcomputer (1) which are connected with the single-chip microcomputer (1), a measured motor (4) connected with the motor speed control module (3), a speed sensor (6) connected with the measured motor (4), and a speed signal processing module (5) connected with the speed sensor (6). The motor speed control module (3) is further connected with the power supply module (2). The high-accuracy motor test system is characterized in that a triode trigger circuit (8) is arranged between the speed signal processing module (5) and the single-chip microcomputer (1). By adopting the system of the invention, the speed of a motor can be tested accurately, and test personnel can better judge the performance of the motor. Through the function of the triode trigger circuit, speed signals are more stable, and the accuracy of speed test is further improved.
