多臺(tái)電機(jī)獨(dú)立控制 控制要求: 為兩臺(tái)異步電動(dòng)機(jī)設(shè)計(jì)一個(gè)控制線路,其要求如下: (1)兩臺(tái)電動(dòng)機(jī)互不影響地獨(dú)立工作; (2)能同時(shí)控制兩臺(tái)電動(dòng)機(jī)的起動(dòng)與停止; (3)當(dāng)一臺(tái)電動(dòng)機(jī)發(fā)生故障時(shí),兩臺(tái)電動(dòng)
直流電動(dòng)機(jī)控制電路-DC Motor Control CircuitNotes: Here, S1 and S2 are normally open , push to close, press button switches. The diodes can be red or green and are there only to indicate direction
音量指示器--Sound Level IndicatorThis project uses an LM3915 bar-graph IC driving two sets of ten LEDs for a 30dB range. The circuit is unique because it has an additional range of 20dB provided by an
簡(jiǎn)單伺服測(cè)試儀電路--Simple Servo Testerclick here to download schematic in pdfThis is a simple servo tester which will comprehensively test the capabilities of almost any modern servo. It has two push
風(fēng)扇控制器電路-Fan controlThis is a simple circuit that will do what you want I believe. R1 15k ohm resistor NTC Thermistor- 10k ohm, sold at Radio Shack in the states. P1 10k ohm potentiometer -
可調(diào)頻閃燈電路--Adjustable Strobe LightThis one uses a much more powerful "horse shoe" Xenon tube which produces more light. You can also control the flash rate up to about 20Hz. Do not look
單極性步進(jìn)電機(jī)控制器電路--Unipolar Stepper Motor ControllerThis is a very good integrated circuit. There is no need for any external glue logic to drive the circuit, there is only 2 pins to drive the
PWM馬達(dá)/燈控制器電路-PWM Motor/Light ControllerA pulse width modulator (PWM) is a device that may be used as an efficient light dimmer or DC motor speed controller. The circuit described here is a gen
黑光發(fā)生器電路 Black Light This circuit is a simple ultraviolate light that can be powered by a 6 volt battery or power supply that is capable of supplying 1 or more amps. Theoritical DiagrammPARTSP
