抄録
EMI in the universal motors remains as a very important problem to be solved and is conventionally evaluated by the remote measurement of noise figure at the distant point from the noise source.<br>In order to clear the mechanism of noise generation in the universal motors, we try to measure the noise pattern near the noise source by using two coils which are installed for direct detection of the time varying arc current and the noise levels in the range of 0.15_??_5 MHz.<br>The experimental results show that the noise levels depend on the time derivatives (di/dt) of the arc current and the wide spread of noise levels are caused by randomness of arc quenching. We also discuss the propagation of noise and the comparison with the conventional evaluation of EMI, using an appropriate procedure of the obtained experimental data.
