摘要： The present invention relates to a method for detecting position of a BLDC (Brushless Direct Current) motor which is capable of decreasing position detecting errors by detecting accurately a crossing time point of a back electromotive force and reference potential by using. a phase voltage outputted from the BLDC motor regardless of an ON/OFF operation of a PWM (Pulse Width Modufation) signal inputted to the BLDC motor, accordingly the present invention can stably operate the BLDC motor, lower power consumption and noise of an equipment installed the BLDC motor stably operating.
摘要翻译：本发明涉及一种用于检测BLDC（无刷直流电动机）位置的方法，该电动机能够通过使用准确地检测反电动势的交叉时间点和参考电位来降低位置检测误差。无论输入到BLDC电动机的PWM（脉冲宽度调制）信号的ON / OFF操作如何，BLDC电机都输出相电压，因此本发明可以稳定地操作BLDC电机，降低功率消耗和安装设备的噪音 BLDC电机稳定运行。
