[font=arial, sans-serif][highlight=#ffffff]I am building a remote control Wagon. I was told I need to buy the Regenerative Motor Driver. (SEE ATTACHED PHOTOS) However, I have the original brain that came with the used motor scooter I purchased; My question is:

][blockquote]Do i plug the motor wire directly into the Sabertooth? [/blockquote]/:m][/highlight][/font][font=arial, sans-serif][highlight=#ffffff]Thank you![/highlight][/font]

It comes down to the following:

  • What is the input voltage rating of the motors (likely 12V, but check to be sure)
  • What is the maximum current rating for each motor (check the sticker, and if it’s not there, you might need to contact the manufacturer)
  • What input method do you want to use (serial, a knob, RC etc.)

Each motor should have two wires. These are plugged into M1, and the two wires from the other motor are plugged into M2. Positive (+) and negative(-) will matter only when you make them work. If one rotates in the wrong direction, swap the two wires. The battery is plugged into the power terminals.

I think there maybe some confusion. I have only 1 motor. The Motor is a 24V Motor. I have attached a picture of the wire connected to the motor in the previous message. I am only using one motor. So:

  1. which is the best input connection to use with my motor? Its a 4 prong female connector. I intend to use a remote receiver for the wagon.
  2. My original question wasn’t answered. Does the Sabertooth take the place of the original brain that came with the Motor?

You’ll need to find out what those other two wires do. They might be for an electrical brake.
Normally you only connect the red and black wires for power.

We don’t carry the mating connector, and in any case, the screw terminals on the motor controller require bare leads, so you’ll need to cut the cables and strip the ends.
The Sabertooth MIGHT replace the “brain” from the wheelchair, but without knowing exactly what features the old “brain” had, it’s difficult to say.
If you can tell us aside from controlling the motors (please specify how), if there are any other features you need, we can tell you if it suits the application.

Yes, I am building a remote control, powered wagon. The old Scooter Controller connected to the two 12V batteries, the motor and throttle. It controlled the scooter’s ability to stop and go. The features I need is to control my wagon in a similar way, except using a Handheld controller.

The other two wires coming out of the motor (Yellow & Black) are for the Electric Brake.

  1. If I am only connecting the red and black wire into the Sabertooth, what do I do with the electric brake wires? Do I just tape and cap them?

  2. What are “bare leads”?

6

  1. Yes, you would just add electrical tape or other way to

  2. Bare leads are wires in which the protective rubber has been removed.

7

Thank you.

  1. So do i place electric tape on the electric brake wires?
  2. Is there a less expensive motor controller that will give me the features that i need? other than the sabertooth, what do you recommend?
  3. What other controllers do i need to connect to the motor controller?
8
  1. Correct (separate the wires of course)
  2. You need a good idea of the continuous current. Normally wheel chair motors are quite powerful.
  3. If you want ti controlled via potentiometer / knob, you need the knob. If you want it remotely controlled, you need an RC remove.

The more details you can provide, the better we can help you :slight_smile:

9

  1. Yes. The wheel chair motor does have a powerful motor. Please tell me what other details you need to recommend a motor controller?

  2. and Yes. my plan is to control the wagon remotely. what is a “RC remove”?

  3. I was told i need a “RF receiver” to wire into the motor Controller.

10

  1. You really need the continuous current under load.

  2. As mis-type… it should have been RC remote (robotshop.com/en/wireless-rc … llers.html)

  3. You can, but it’s not necessary. The Sabertooth is really versatile and can take a variety of inputs, including serial from RF (but this is likely overly complex for your case).

11
  1. Is there a less expensive Sabertooth or motor controller that you recommend?
  2. What do you mean by “under load”?
  3. The RC remotes really vary in price. Will either of these two get the job done:

12

There are a variety of Sabertooth models, but you need to know the current requirements of the motor under load (i.e. what current does the motor consume when it’s used in the most strenuous of situations with full payload weighing down on it).
Either controller would work.

13

this is the Wheel Chair model that i took the motor from. Please let me know if you see the motor under load?

The current draw is not specified in that datasheet. You’ll need to contact the company.
They should have no problem helping you since you already have the product.

15

Ok. I’ll contact the company. Just to be clear:

  1. i need to request a “Data Sheet”?
  2. do you respond to queries on Saturdays?
16

OK. Here is the Data Sheet: I don’t see the motor under load. Or maybe i’m missing it?

Please let me know if this will work?

That is the datasheet for the complete unit - not for the motor.
We need one specification for the motor itself - continuous current under rated load.
Even the stall current would help.
We do not reply during weekends.

I called the company and the lady over the phone could only offer me the data sheet for the complete unit and throttle control lever operation. All of which she read of their website:

pridemobility.com/resourcece … anuals.asp

There is not specification for the motor itself. Based on the fact that they recommend a maximum weight of 275 lbs. Can you please make certain assumptions and recommend a motor controller?
