Abstract: Aiming at accurately, quickly and easily realizing the speed testing of DC motor, the embedded microprocessor LPC2114 with A/D converter module and USB interface chip CH372 were used. The hardware design of the DC mortor with no load pulsating current testing system was finished. Precise data samplings of pulsating current, voltages and DC current were realized. The research results show that the research lays the foundation for the further more analysis of DC motor pluse waveform.
