Embodiment Construction
[0028] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.
[0029] like figure 2 As shown, a high-precision phase-locked motor speed controller is used to control the motor 6, including
[0030] A first counter 1, whose function is to count the period of the external input reference square wave signal SYN according to the frequency CLK to obtain the count value n, whose input terminal 1 is connected to the external clock CLK, and input terminal 2 is connected to the input terminal of the reference square wave signal SYN connected, and its output is the reference signal SYN period count value n;
[0031] A second counter 2, whose function is to count the period of the Hall signal according to the frequency CLK, to obtain the co...
