摘要： A brushless motor control apparatus includes a mask processing unit to which digital induced voltage signal is input, a energizing current timing generation processing unit, a pulse width detection unit, and an advance angle correction unit for performing advance angle correction. The pulse width detection unit measures pulse width of spike voltage, and the advance angle correction unit calculates the correction to the advance angle according to the length of this pulse width. The energizing current timing generation processing unit takes half the value obtained after subtracting the correction value from the edge interval of the position detection signal generated in the mask processing unit as the advance angle.
摘要翻译：无刷电动机控制装置包括输入数字感应电压信号的掩模处理单元，通电电流定时产生处理单元，脉冲宽度检测单元以及用于进行提前角校正的提前角校正单元。脉冲宽度检测单元测量尖峰电压的脉冲宽度，提前角校正单元根据该脉冲宽度的长度来计算对提前角的校正。励磁电流定时产生处理单元将从在掩模处理单元中生成的位置检测信号的边沿间隔减去校正值后获得的值的一半作为提前角。

摘要： When starting a brushless motor, if the stop position of the rotor is detected between time t1 and time t2, a start-up excitation pattern in accordance with the rotor stop position is input for an initial energization time Ts1. Afterward, when the energization is stopped, a plurality of signals SL1, SL2, SL3, SL4 are generated in sequence in excitation switch timing signals in accordance with the rotational position of the coasting rotor. From these signals SL1 to SL4, the rotor position is detected using the second and subsequent signals SL2 to SL4 and then the process shifts to ordinary energization switch control. In accordance with the present invention, it is possible to start up a motor in a short time with a simple method so as to obtain a large torque during start-up.
摘要翻译：当启动无刷电动机时，如果在时间t 1和时间t 2之间检测到转子的停止位置，则输入根据转子停止位置的起动激励模式以用于初始通电时间Ts 1。此后，当通电停止时，根据滑行转子的旋转位置，在励磁开关定时信号中依次产生多个信号SL 1，SL 2，SL 3，SL 4。从这些信号SL 1〜SL 4中，使用第二和后续的信号SL 2〜SL 4检测转子位置，然后转移到正常的通电开关控制。根据本发明，可以通过简单的方法在短时间内启动电动机，以便在起动期间获得大的转矩。
