摘要： PROBLEM TO BE SOLVED: To provide a position detection circuit and a motor controller wherein rotor position detection signals are favorably obtained over the entire PWM control range, and rotor position detection signals can be favorably obtained even in PAM control.
SOLUTION: The controller for brushless motors detects the magnetic pole position of a stator based on the terminal voltages of stator windings in individual phases, and thereby controls power application to the stator windings. In this controller, detection voltages corresponding to the terminal voltages are compared with a reference voltage, and resulting comparison result information signals are inputted directly to the control circuit. Thus, the rotor position of a motor can be favorably detected and the motor can be favorably controlled from immediately after power application switching without providing a period in which the detection of rotor position is prohibited.

摘要： PROBLEM TO BE SOLVED: To provide a motor control means which is provided with a commutating phase control means which changes the commutating timing of the winding of a motor and can always operate the motor highly efficiently over a wide operating range, by changing the commutating phase of the winding of the motor in accordance with the speed and load of the motor. SOLUTION: Whether PAM control or commutating phase control is being made is discriminated (Sh). When the commutating phase control is made, whether the speed deviation calculated through processing (Sb) is positive or negative is discriminated (Si). When the speed deviation is positive, namely, a speed increase is required ('Yes' in Si), a commutating position command is reduced by a certain preset value (Sj). When the speed deviation is negative, namely, a speed decrease is required ('No' in Si), on the contrary, the commutating phase command is increased by a certain preset value (Sk). Since the commutating phase command has the value used for calculating the delay time until a drive signal is actually changed from the changing point of a position detecting signal, the phase advances as the command becomes smaller. In other words, the more the value of the commutating phase command becomes smaller, the more the speed increases.
摘要翻译：要解决的问题：提供一种电动机控制装置，其具有换向相位控制装置，其改变电动机的绕组的换向正时，并且可以在宽的工作范围内高效率地操作电动机，通过改变换向相根据电机的速度和负载对电机进行绕组。解决方案：是否对PAM控制或整流相位控制进行了辨别（Sh）。当进行换向相位控制时，判断通过处理（Sb）计算的速度偏差是正还是负。当速度偏差为正时，即需要增加速度（Si中为“是”）时，换向位置指令减少一定的预设值（Sj）。当速度偏差为负时，即需要减速（Si中为“否”），相反，换向相位指令增加了一定的预设值（Sk）。由于换向相位命令具有用于计算直到驱动信号从位置检测信号的变化点实际变化的延迟时间的值，所以相位随着指令变小而前进。换句话说，换向相位命令的值越小越快速度增加。
