00:07Hello friends, today I will present the speed control of a motor using a SCRUJ.
00:15This circuit converts a direct current voltage to alternating current, and includes a center-tapped transformer, resistors, and capacitors.
00:24and transistors,
00:25For this, we will convert from a 12-volt DC voltage to 127-volt AC. Another way to check is with
00:32Using a voltmeter, we placed a 17 kiloohm resistor and measured each of the output voltages.
00:39of the terminals.
00:45The motor's power circuit operates as follows: when a current voltage is applied
00:52BC continues, to the RC series circuit, formed by a variable resistor, a potentiometer and a capacitor this begins to
00:59load,
01:00Since this capacitor is connected to the emitter, when the voltage exceeds the UJT, the UJT will begin conducting due to the
01:07unique resistance value,
01:09The use of the SCR is to regulate or control the firing times, and thus control the motor, by means of a
01:15DC to latest converter.
01:27That's all, don't forget to subscribe, thank you.
