High Frequency Noise Analysis "Brush Noise Analysis"
Example of motor brush noise wraparound analysis
An analysis of motor brush noise on the control board was conducted. When an impulse signal simulating brush noise was applied, significant noise was confirmed to be superimposed on the CPU communication signal terminal. It was found that inserting a 0.1μF capacitor at the motor terminal could significantly suppress the noise at the CPU terminal. However, using low-frequency electrolytic capacitors with self-resonance as noise killer capacitors was found to worsen the noise level at the CPU terminal compared to not using a capacitor. 【Features】 ○ The communication signal enters the CPU communication terminal via the path X1→IC3→CPU. ○ Investigate the effects when impulse noise is applied to the motor terminal. ○ Noise analysis requires an analysis of the entire board, including the implemented components.
