    Power requirements in amp hours for project

    Yes, the cart goes over blast furnaces which temperature may reach over 200 F. So cables are undesirable. electrical/mechanical components will be on the cart (isolated and cooled).

    Power requirements in amp hours for project

    Yes, it is exactly the same idea alephzero pictured. The cycle is 120 times/day. So, 5 min charging and 7 minutes down time. The idea is to not have an operator near the cart when the doors open and unload.

    Power requirements in amp hours for project

    Hi berkeman, there is an alternator attached to a wheel which produces electrical charge. Cart moves through a winch. I am planning on installing 3 * 125A.h 12V batteries. Power numbers are for opening gates in the cart. The cart is fairly large (10 tons).

    Power requirements in amp hours for project

    Hi guys, I have been working on an automation of a cart. The cart wheels are producing a current of 14 Amps for 5 minutes for every cycle(1.16 Amp hour stored in a battery). while the cart is running there are 2 actuators operating. One actuator uses 10 amps for 5 seconds (only 0.01388...

    Low RPM alternator to charge 12V battery

    Hi Jack, When actuators are operated the cart will always be at rest, so all the current is drawn from the battery. That is why it may not work. A car battery in normal conditions is under much lower usage than in this application. However, I am now thinking of using a rotary actuator and using...

    Low RPM alternator to charge 12V battery

    jack action the actuators require 12V thank you for your reply, so If one alternator gives me 0.52A.h of charge on one wheel. Can I install 1 alternator on each of the four wheels of the cart to get 2.08 A.h?. I have been reading about the 12V batteries and it has come to my attention that...

    Low RPM alternator to charge 12V battery

    an AC motor, a constraint of my design is not to have any other cable connecting the cart except for the winch cable.

    Low RPM alternator to charge 12V battery

    What is my best option? getting more batteries in series or parallel? or should I get 1 alternator for each wheel and actuator?

    Low RPM alternator to charge 12V battery

    Hi guys, I am working on a school project. I have an inclined cart mounted on rails moved by a winch. I would like to install an alternator on one of the cart axis, so I can charge a 12V car battery - 20Ah. The wheel turns at 12 RPM. At that speed the alternator will not work, so I am also...
