I am an engineering student and my capstone project is to design and build and electric cart to transport two welding cylinders. We have the cart designed and now we are trying to determine a motor size. Calling manufacturers hasn't gotten me anywhere.
~ 600 pounds
walking speed (~3 mph)
15 degree max incline
Can anyone provide guidance ?
The benefits of the reverse relay and SPDT toggle switch are that the switch can be mounted away from the contactor so the heavy gauge controller to motor wires do not need to be ran to the location that the switch is in. The switch to relay wires can be a thinner gauge than the motor wires are such as 18 AWG or 20 AWG. The toggle switch is also easier to use and requires less force to switch between forward and reverse than the rotary reverse switch does. The reverse relay also has the benefit over the rotary switch of shorting the motor leads together when the toggle switch is in the off position which acts as a parking brake. The reverse relay has three modes: Forward-Park-Reverse
We also have a handlebar mount SPDT rocker switch that can used with the reverse relay is item # SWT-39 sold on this page:
