Technical field
The present invention relates to a kind of motor circuit system, the power-saving control circuit system of espespecially a kind of motor.
Background technology
It is general to treat rotation mechanism, motor driving is suffered from, the driving voltage of the motor is persistently supplied, but due to horse
The rotation voltage reached often forms the variation of string wave progress, this when motor voltage is more than zero, that is, generates work when rotation mechanism
It is dynamic, but motor no matter this treat rotation mechanism whether start, constantly persistently supply electric power, therefore actually this treats that rotation mechanism is being transported
Row process has its inertia operated, which does not need to continued power and can operate, and otherwise generates meaningless electric power consumption
Take.
Although it is also taken in current motor design, when motor virtual voltage deficiency（It is depressurized）When, although motor meeting
It generates and just turns, but the design and setting of time switch can be used（Such as after several seconds）, MCD（Triangular form wiring）It opens,
MCM（Major electromagnetic contactor）It closes, is short-circuited using circuit and motor is caused to obtain full voltage, then full-speed operation.But
Such design mainly switches operating efficiency using with " timing ", can not fully not react the required voltage of rotating speed and become
Change and whether provide the function of startup.

Specific embodiment
Referring to Fig. 1, shown in cooperation Fig. 3, the present invention waits to turn about a kind of control circuit system of motor 2 for driving one
Mechanism（Such as fan, electric tool, compressor, washing machine, dewaterer, clothes drying machine, food conditioning device, refrigerator and other can be by
Mechanism of motor driving etc.）, the present invention includes：
One motor 2：It is driven by alternating current；
One switch 5：It is electrically connected with the motor 2, the electric current of the motor 2 is led on and off；The switch 5 is more
It is connected with wind up wave switch 5A and a lower edge wave and switchs 5B.The switch 5, which can more connect, sets a Safe control switch（Figure is not
Display）, it is electrically connected with a processing unit 1, it is still necessary to change state after energization, the specified conditions according to setting can just open
Move the motor 2.In addition the switch 5 can also increase by a circuit for leading to 2 electric current of motor for reverse-conducting（Figure is not shown）, make
The motor 2 can be reversed rotation.
One processing unit 1：It is electrically connected with the switch 5；The processing unit 1 includes a voltage and controls formula 11；
One sensor 3：It is electrically connected with the processing unit 1；A wherein embodiment is a resistance 3B and two senses
Capacitance 3A is surveyed to be electrically connected.
One converter 4：The converter 4 is electrically connected with the processing unit 1；
Voltage control formula 11 must be performed when the motor 2 rotation voltage is equal to a setting value, i.e. the horse is led in conducting
Up to 2 electric current, and before when the motor 2 rotation voltage is again equal to the setting value, close the electric current towards the motor 2.
Fig. 2 effect diagrams of the present invention are please referred to, the display present invention is in time carry out process, when the motor 2 rotates
When voltage is equal to a setting value（Preferable setting value is zero）It can be started with START (S1) state, and terminated in END (E1) state.
Therefore many meaningless electric power can be saved to consume.And it is again equal to setting value START (S1 ') in the motor 2 rotation voltage
When before, close the electric current towards the motor 2, stop power supply and by treating that rotation mechanism transporting using 2 rank sections of the motor
Operating inertia, the motor 2 can not need to continued power and can operate caused by row process, save the output of electric power.And this
Invention be using the sensor 3 make accuracy variation detect, with the processing unit 1 be electrically connected and compared with.It is accurate
Degree is higher, and it is non-detected with timing, but with practical dynamic detection, accuracy is promoted.
