60W regular ac motor needs to be fast and slow before stopping, how to control?
The thyristor is used to adjust the voltage, and the PID controls the SSD control signal from the thyristor, which is only a deceleration system, and the rest is controlled by the time relay and the contactor
2 l talk nonsense, what do you do to show me, let me explain, first, to see what is your motor under common law, if the three phase is much more easy, can also be single phase, three-phase can use frequency converter, the acceleration and deceleration, such as 2 s up to full speed, 50 seconds to slow down to 0, no inverter single-phase, individual can be addressed by transformer, time relay, contactor, such as a startup, you give him a full voltage, stops, you give him 80% of the voltage, at 70%, to 60%, so cut down slowly, variable voltage, through the transformer to solve, to a number of different levels of transformer, or more output voltage transformer, as well as by PID controller and SCR, thyristor can adjust voltage, and can also use the sliding resistor to solve, or sliding transformer, or resistance, change the voltage, to reduce the speed, way to many oh
You want to know how fast you're talking, how long does it take to stop the process and how long does it take to complete the process?
