i have a project of sorting of packages on a conveyor using RFID tag. i was interested in programming only but now i have to design a conveyor as well so what i did was, i salvaged a treadmill and convert it to a working conveyor but now the problem is the motor control circuit in it is broken and now i am thinking of doing what this video below says :
my motor specs are :
permanent magnet DC motor
1.5 HP @ 100VDC
14 amps
4900 RPM
as you can see this speed is too much for my project, inside the treadmill i reduce the pulley mechanism and will remove the flywheel off the motor so it will reduce the speed (low radius pulley to larger radius pulley)(gear ratio). now if i do what this video telling me than how can i counter the fact that when load is increased speed will get much lower, i want a constant speed. i thought that i can plug current sensor and when load increases current will increase and i will control it using arduino to stabilize the current to make the speed of belt constant.
this is my final thinking
220 vac 50 hz convert from transformer to 120 vdc > scr controller > bridge rectifier > motor >sensor feedback > arduino
Please guide me.
