Embodiment
Extremely shown in Figure 2 as Fig. 1, a kind of speed-change control device 10 that a preferred embodiment of the present invention provided, in order to adjust the rotating speed of a motor 51, this motor 51 is to be applied in the cutting machine tool (not shown), circular sawing machine for example, speed-change control device 10 mainly has one first Circuits System 11, an one second circuit system 21 and a selections switch (switch) 31, wherein: first Circuits System 11, in order to one first voltage to be provided, wherein, first Circuits System 11 has an external power source 12 and a starting switch 14, external power source 12 can be an AC power, starting switch 14 is serial connection external power sources 12, and when starting switch 14 short circuits, this external power source 12 will provide this first voltage.
Second circuit system 21, in order to one second voltage to be provided, this second voltage is less than this first voltage; Wherein, second circuit system 21 has a power semiconductor assembly 22, a voltage stabilizing rectification circuit 24 and a microprocessor 26, and power semiconductor assembly 22 can be the bidirectional silicon-controlled body of TRIAC in present embodiment, in order to this second voltage to be provided; This voltage stabilizing rectification circuit 24 has a diode D1 and is connected in starting switch 14, and has a zener diode ZD1 capacitor C 1 in parallel, voltage stabilizing rectification circuit 24 is to be connected in starting switch 14 with diode D1, when being used to starting switch 14 short circuits external power source 12 is transferred to a direct current power supply; Microprocessor 26 is that the program-controlled device with model EM78P153S is an example in present embodiment, have a power supply pin 261 and be connected in voltage stabilizing rectification circuit 24, and have an external power source input pin position 262 and be connected in starting switch 14, and have a control pin position 263 and be connected in power semiconductor assembly 22, microprocessor 26 is that foundation one preestablishes, and exports a trigger signals conducting power semiconductor assembly 22.Selections switch 31 (switch), have contact 32 and one first docking point 34 and one second docking point 36 altogether, contact 32 is to connect motor 51 altogether, first, second docking point 34,36 are connected to external power source 12 and power semiconductor assembly 22, selections switch 31 is the operations according to a user, switches with this first voltage or this second driven motor 51, by the rotating speed with change motor 51.Speed-change control device 10 in the present embodiment can more include: two choking-windings 41; be connected to common contact 32 and motor 51 between; and starting switch 14 and motor 51 between, can provide the effect of filtering, by being influenced by high-frequency current so that protection motor 51 is unlikely.
By by said structure, can see through starting switch 14 and start the present invention, again by select the rotating speed of motor 51 by selections switch 31, when selections switch 31 switches to common contact 32 and 34 conductings of first docking point, be directly to take AC power, the i.e. running at full speed of motor 51 this moment; When selections switch 31 switches to common contact 32 and 36 conductings of second docking point, then be to take the power supply that power semiconductor assembly 22 is controlled, and power semiconductor assembly 22 is the phase control that triggering signal gave that are subjected to microprocessor 26, produce specific conducting state, it is tuning to carry out pulse duration to AC power, by the output with control voltage, the rotating speed of motor 51 promptly can thereby be controlled.In addition, because microprocessor 26 is to export this triggering signal according to this default settings, therefore pass through by changing this default settings, can make the different voltages of power semiconductor assembly 22 outputs that are subjected to microprocessor 26 controls, so the present invention is except that two sections speed changes being switched by selections switch 31, the switching device shifter that can change this default settings if arrange in pairs or groups again, then can reach the effect of multistage speed change, that is, when selections switch 31 switches to common contact 32 and 36 conductings of second docking point, can also utilize microprocessor 26 to control the running rotating speed of motor 51.
