Industrial electricians - motor control and remote questions

[Riverman]

I'm going to install a new more powerful motor on the winch for my marine railway. I want to have a low voltage remote control for up and down operation, either wired or wireless. Wireless preferred!

Two part question - what kind of components do I need for the control (relays, low voltage), and does anyone know of an adaptable kit that I could make the control wireless?

I need a project obviously!

I have wireless remote for my boat lift 220 volt and Gem remotes .com makes it works great check out there site. Good luck Eric

I looked at their stuff, it's nice but I want to make my own. Looking more for ideas for a home made solution.

Get a small VFD that will give you forward/stop/reverse and tie it into a wireless kill switch like I put on my two four-year-old Grandson's Yamaha PW50s.

The switch would be wired to the VFD terminal board's C to F terminal for forward run and have a reversing switch to make it trigger C to R for reverse. The drive could set the speed that you want the winch motor to operate at from the VFD's keyboard.

What is a VFD?

vairable frequency device aka a rheostat, speed controller, ya know like on a wall switch for a house light or on the end of that thing in the drawer on the other side of the bed lol

You could probably adapt a hobby-type R/C device to accomplish the task.

LOL I found Carymart this afternoon and was looking at contactors on ebay after a short chat with an electrician at work. I think this is how I will go.

What is a VFD?

It's a variable frequency drive, and it can also serve as an inverter if you have a 3 phase motor but only 1 phase supply voltage... It regulates the hertz of the electricity going into the motor for a nice speed control, and can act as a soft start due to how low it can be dialed down...

In regard to a remote start, my job never requires me to do a set-up like that but can undoubtedly be done... Like Pyro stated the RC world uses remote-to-motor technology endlessy, and you can also consider that an electric garage door opener w/remote is the same principle...

I don't really want a speed control as the winch runs at a good speed right now. The old motor runs at 1725 too, into a 45:1 worm drive gearbox. I have the cable running out and back through a pulley as well to reduce strain on the cable so it runs pretty slowly. That's good because I move pretty slowly. :)

I was looking at the Carymart stuff, do you think any of those would work without a contactor? I know a garage opener uses this type of switching but I'm using 6X the motor.

[Riverman]

This one looks like it might work.

Says the controller can handle 300W at 220, pretty sure that's not enough for a one hp motor. This could work with a contactor though right?

A motor is an inductive load that has a large inrush current until the stator is fully saturated with the magnetic field. Most contactors have two ratings, a amperage rating for resisitve loads and a horsepower rating for inductive loads. Clear as mud?

Clear as can be. You need some big f#&%ing Square D relays.

Yes that makes sense. Then if a contactor is rated for 1 hp it will work for me.

Is this for contactors? If so does he have used stuff?
