This diagram tells us about how to use L200 device for the speed control of permanent magnet motors. By means of R1 and R2, we can obtain the desired speed, proportional to the voltage at the terminal of the motor. Vm= Vref (1+R2/R1) We can use this following equation …
Read MoreDC drive for a Universal motor is shown in figure below. In order to supply DC current to the motor, a diode bridge has been added around the motor. The motor current freewheels through the diode bridge after the TRIAC current crosses zero. To limit the rate of fall of the current as …
Read MoreSwitching Regulator for High Power Efficiency When you should regulate a high voltage to a much lower voltage, switching regulator must be the only choice. Fortunately, a simple switcher integrated circuit chip is available, let you build a complete step-down switching regulator using five components. The switching regulator IC used in …
Read MoreDC to AC inverter is used to convert DC voltage source to an AC voltage source. DC AC inverter circuit works by switching the DC voltage source to make an alternating current that flow to a transformer. Here is an example of dc ac inverter schematic: This power inverter could generate 120 Watts …
Read MoreWhat is A pH Meter? A pH meter is actually a precise voltmeter that measures the generated voltage of a pH electrodes. The requirement of such meter is high input impedance and has the gain of voltage-pH conversion. The standard pH probe generate voltage about 59 mV per pH, so all we …
Read MoreTo get a position control that are low cost, accurate and simple we can use stepper motor. To drive it we can use a circuit mounted close to the motor, and to control it we can use remote control circuit via long cable. The power for both motor and the driver circuit is carried over …
