According to frequency signal with tach signal obtained by converting) to produce corresponding feedback signal, and by feedback/speed control signal line
263 to feed back to control device 22, therefore, control device 22 can be to judge motor apparatus 24 according to the feedback signal for receiving
It is no to be acted with correct rotating speed under specific sequential.
Wherein, the speed control signal that the control device 22 is produced can be pulse signal (such as electricity produced by control device 22
Pressure signal or voltage control signal), the integration of pulse width modulating signal or above-mentioned pulse signal and pulse width modulating signal believes
Number.Motor apparatus 24 can be brushless motor, and the rotor 242 linked with motor apparatus 24 can be fan；And motor apparatus 24 are produced
Raw feedback signal can be the tach signal or frequency signal of motor apparatus 24；The control computing signal of circuit 241 then may be used with data
By control elements such as its internal motor driving chip, microprocessors ... to realize, and (can more not painted by switch element
It is shown in this figure) to be coupled between control element and feedback/speed control signal line.
Below then further according to the invention discloses motor apparatus and motor control speed system proposing two kinds of different implementation states
Sample, please respectively refer to shown in Fig. 3 and Fig. 4.
Refer to first shown in Fig. 3, it is that, using a kind of brushless motor 34 of the invention, it links a fan 342 and drives
This fan 342 is moved to be rotated, and brushless motor 34 is by a positive power signal line 261, a negative power signal line 262 and
Feedback/speed control signal line 263 is being coupled to a control device 22.Wherein, the control device 22 produces and is used to control brushless motor
34 speed control signal is simultaneously believed by feedback/speed control signal line 263 with the rate controlling transmitted to brushless motor 34, and in this implementation aspect
Number it is voltage signal, after brushless motor 34 receives the voltage signal of rate controlling, its internal control element, such as motor drive IC
Or microprocessor 341 then according to this voltage signal and driving voltage (for example：The Vcc of full position) between relation calculating correspondence
Rotating speed, and using the rotating speed that calculates to drive brushless motor 34, and then drive fan 342 to rotate, while microprocessor 341
More by switching frequency (that is, the fan 342 of a phase detecting circuit (not being illustrated in figure) detection brushless motor 34 reality
Actual rotation speed), to produce corresponding feedback signal (such as frequency signal), then by feedback/speed control signal line 263 with general
Feedback signal transmission is to control device 22.
Although to rate controlling voltage signal and feedback signal by feedback/speed control signal line 263 with transmit, but
Because two kinds of transmission directions of signal, property and frequencies are differed, therefore the interference between two kinds of signals can't be caused,
Do not interfere with control device 22 and relative rotation speed is being fed back just to the control efficiency or brushless motor 34 of the rotating speed of brushless motor 34 yet
True rate.

Ripple unit, wherein this filter unit include a high-pass filter 521 and a low pass filter 522, and high-pass filter 521 is whole
Close the microprocessor 341 internal in brushless motor 34 and with it to couple, low pass filter 522 is then incorporated into control device 22
It is interior.
Control device 22 produce be used to control the speed control signal of brushless motor 34 and pass through feedback/speed control signal line 263 with
It is the pulse width modulating signal with upper frequency to transmit the speed control signal to brushless motor 34, and in this implementation aspect, because
This, after brushless motor 34 receives the pulse width modulating signal of high frequency, first with the high-pass filter 521 inside it with general
The signal of other lower frequencies is entered back into microprocessor 341 after being filtered, and makes microprocessor 341 wide according to this pulse
Degree modulated signal to calculate corresponding rotating speed, and using the rotating speed for calculating driving brushless motor 34 to be rotated and then band
Dynamic fan 342 is rotated, while switching frequency of the microprocessor 341 more according to the reality of brushless motor 34 is producing corresponding feedback letter
Number (for example：Frequency signal) and by feedback/speed control signal line 263 with transmit, and compared to pulse width modulating signal for,
The frequency of feedback signal compared with pulse width modulating signal for low, therefore, come from brushless motor 34 feedback signal can first via
Low pass filter 522 after the noise for filtering other frequencies entering back into control device 22.
Further, since above two implements aspect is all the application of brushless motor, wherein being used to the reality of brushless motor
The phase signal sample circuit that rotating speed is converted into feedback signal can be hall sensor, therefore can be by hall sensor with elder generation
The switching frequency of brushless motor is detected, and then the switching frequency that will be detected is back to the control of brushless motor inner control circuit
Element is carrying out computing and be converted into the feedback signal that control device can read.Because the detection of this signal is with conversion method
Existing technology, therefore do not repeat herein.
It can be seen from technical characteristic according to above-mentioned exposure, a kind of motor apparatus proposed by the present invention and motor control speed system are utilized
Holding wire transmission speed control signal and feedback signal with two-way transmission capabilities, are simplified integrated circuit framework, while
Reduce the expenditure of overall hardware cost, reduce the man-hour of assembling, and can reduce single element failure due to the reduction of component and
Cause the probability of overall architecture failure.
Illustrative is the foregoing is only, rather than is restricted person.It is any without departing from spirit and scope of the invention, and to it
The equivalent modifications for carrying out or change, in should be included in claim of the invention.
