Electric Engine Controllers

Postby FLtenwheeler » Sat Nov 04, 2017 4:42 pm

Hi

I have 2 electric 1-1/2" scale locomotives that I am working on. They both have the same permanent magnet traction motor drives. I am looking for wireless (RC) controls that I can MU with.

Thanks

They make just what you are looking for if the current isn't too big. The current limit for their largest unit is 150 amps. If you are using only one motor drawing over that limit you can try 4QD. If you are using multiple motors per engine you are in business by just MU'ing them. You can consider a 4QD controller with their R/C interface if you need up to 300 amps. It works with any R/C system like ground cars etc. since it uses a receiver from any maker. I used it in a box cab I built. The only problem is distance. It's not great.

I've had good luck with the Syren50 controller from Dimension Engineering. A sample wiring diagram can be found here:

Be sure to let us know which system you decide to use, and how well it works for you.

Regarding the request for information on remote control for 7 1/2" gauge locomotives. Here is what I use.

I use a 4QD-200 controller powering 2 -- 5/8th hp RMI motors. I use 24 volt RMI motors and two yellow top batteries.
A 15:1 gear ratio gear box from RMI.
I built an interface for a simple four function Futaba controller. I have direction, speed, and horn controls, no other functions needed for my application.

The range is about 1/4 mile or so with no problem. I use it every day for my signal maintenance duties at Maricopa Live Steamers in Phoenix, AZ. We have ~ 18 miles of track in use at this time, so it gets a workout every day.

Terry,

This sound really interesting. If you get a chance, could you post a pic or two of your interface? I'm building a little battery powered M.O.W. unit and bought a Chinese motor controller online for about $60. It says it's capable of 70A which is more than I need. The controller came with a nice pot for speed control and a rocker switch for direction control, but remote operation would be nice.

Thanks,

Joe

The interface would be a bit more complicated since you have a rocker switch to change direction. The 4QD uses 24 volt / ground input to change direction. Latching relay set and reset by servo contacting micro switches. Servo linkage to pot with mechanical connection for about 120 degree rotation of pot. Horn function has servo closing micro switch to activate high current relay.

The direction and horn use the self centering controls. The speed is controlled by the throttle function.

I have relays in design to switch between remote control and manual operation.

The Dimension Engineering Syren50 seems like a fit to my situation (see thread I started 24v Reversing switch)
The linked wiring diagram does not identify several components nor give specs for them. Could anyone fill in the blanks so I can unspderstand the circuit and order components?
