Well , it looks like there is more way's than one to skin this cat , motorized variac , motorized autotransformer , VFD etc. I don't understand how to use a varible frequency drive for this purpose , but the rest seems clear enough . I think the idea that looks the easiest and cheapest from my...
mc5w, thanks for your input , I believe you understand the dynamics of the vibrating tray I am using but I need to control the take off speed of the vibrating tray . Can you do this with a autotransformer and a singlephase VFD ? If so , how ? Once turned on and speed is increased by turning up...
nbucska , here is the link , only look at the vibratory feeder . The control box will only turn the vibrater on/off and adjust the speed or strength of the vibrations http://www.eriez.com/resources/brochures/pdf/vibratory/vb30005smallfeeders.pdf
jraef , I have seen the motorized vibraters with the weight at one end to cause a offset motion , this isn't that , the best way I can describe the method would be your solenoid type description. It vibrates a horseshoe type magnet on top of a set of metal E shaped plates set on it's side. Any...
What I need to control on start up is not a motor at all. but an electrol magnetic vibrating feeder tray 120 volts , 3 amps , 60 cycles . If it comes on all at once , material will move down the feeder tray by way of vibrating to a pulverizing machine and over amp , if not speeded up...
Hello, I am new to your forum, what a wealth of knowlege and experience. My problem lead me here.I know you guys can help....I need to be able to control ramp up speed of a vibratory feeder tray ,say under $300.When I switch it on I want voltage to go from 0.volts to 115volts in three minutes or...
