- In this video I will explain how I was able to use a Ryobi 40v brushless motor as a drive motor in my electric lawn tractor conversion. I show how to wire it to an E-bike controller that I purchased on eBay for about $35 to the Ryobi 40v motor and use the Ryobi 40v batteries. This allows you to have both forward/reverse controls and a variable speed throttle. I will include a link to the directions it came with below. I will also include links to the parts I purchased, although the may not be available from the same place when you view this video.
Here is the link to the wiring diagram and instructions that came with this controller, in case you lost yours or didn't receive any:

You can reverse the motor with the original Ryobi controller. If motor leads X,Y,Z are connected to the controller leads A,B,C and you switch, for example, X to B and Y to A, the motor will reverse. You could wire up a double pole, double throw switch (DPDT) switch to accomplish this. As a side note, it is therefore not important how motor leads XYZ are connected to the controller leads ABC (ie, do not need to match colors) as the motor is a Y type configuration for the stator coils. You can just change the direction of rotation as you showed by connecting the learn function wires.
I hadn't thought about using a double throw switch to change the direction on the original controller. I don't have any need for that right now, but always good to remember if I do. Thanks!
@@oddjobsandrandomprojects It's just easier to use a controller (such as the one that you have shown) that has the connector for the reverse function instead of using a DPDT switch. I just made the above comment if someone has the Ryobi controller and wants to make it reversible. I am very pleased to have found your videos as I will be using your approach for doing a conversion. I like the idea of using brushless DC motors and I believe your approach is the simplest and most cost effective.
Excellent video
Thank you very much!
Can you make a video on how you gutted the charger to use only the ground and power pleaseeee
I'll try to get to that soon. Been a little behind on my videos. But, in short, I completely removed the circuit board from inside. Then solder two wires to the two main terminals. I used 10 gauge wire, but that's a bit overkill. Then I just drilled a place for the wires to exit and put the case back together.
So would the brake be a reverse current so the motor briefly goes in reverse so it comes to a stop?
I haven't actually used it yet, so I'm not quite sure. That could be it, or it could simply cut the throttle in case you still had it engaged.
how did you get the ryobi op404 apart, there is only 2 screws, and i cant pull it apart, or is there a hidden screw..thanks
There are two more screws hidden under the sticker as I recall. You can find them if you run your fingers over the sticker firmly.
Do you think you could do 2 or 3 of those motors in parallel and have them all controlled with one controller?
I have seen it done, but in real world conditions it doesn't work well. If one motor has a heavier load it can't compensate. Also you would need a controller with more power. However there is a way to connect 2 or 3 motors to an equal number of controllers, but with 1 throttle to control them all. I've seen diagrams for that when they make 2 motor ebikes.
If I had a stand alone non ryobi motor and non ryobi controller can you explain how to utilize the ryobi batteries? Sorry very new to the electrical side of things and working on converting my mclane reel mower from gas to electric. My last hurdle is I’d like to use my batteries for my ryobi system but am not looking to gut my ryobi to harvest the motor and controller.
Kind of depends on the controller. The batteries are 40v with a simple hot and ground wire. That is pretty easy. I bought a used charger cheap on eBay to make connecting to the battery easy. Just gutted the charger and soldered wires to the hot and ground connectors. The issue with some controllers is they may have additional wires, just as temperature sensors and things to bypass. I'm not familiar with any other brands to offer any advice there. The other option is to purchase a Ryobi motor and controller on eBay like I did. Someone else had already gutted one.
@@oddjobsandrandomprojects thanks for the reply!! My concern about using the ryobi motor for my project is I am just not sure about taking a motor that is designed to run facing one direction but the device I’m placing it on would be using it with it on its side. At least someone said to me it could stress the motor. I am fine with purchasing what I need or tearing apart my ryobi but I just like the idea of using the batteries but want to make sure I’m running efficiently
I don't personally think that running it on its side will hurt the motor. However, the bearings aren't made to take tension. So when I used one for a drive motor with a V belt it runs the bearings after a year or so. The V belt just requires too much tension. I switched to a cog belt and so far have had no problems. Since you are working with a reel mower I'm guessing it is chain drive, which should work well if you can find a gear to match.
Could you use that controller in place of the mower blade controller?
There is no reason you couldn't do that. You would need to figure out a throttle for it, but that shouldn't be too difficult. But it does give you more control.
Have you tried running one of the Ryobi motors on 48V?
I have not tried it, but I have wondered about that myself. It should work, but may cause excessive heat. So it may require a cooling fan to prevent damage in the long term.
I'm a retired electrical engineer and have several conversion projects with 48v motors powered by 56v Ego batteries. One minibike I converted 2 years ago has extensive use with no problems. Most of these motors seem to withstand 10% +/- voltage without adverse effects. I'm considering an electric conversion on my John Deere 318 and considering the Ryobi motors for the deck. I'm going to buy one and do some testing.
hey I really appreciate your help on this stuff!! Check out the use of these on my mower.
I run most brushless at 20-50% more than rated voltage without issue before seeing diminishing returns heat wise. Routinely run 48v motors at 72v nominal, and 72v motors at 100-120v. I run them on mini bikes. it will handle 48v easy.
please help, i have a 900w 40v controller, i found this info on the net, i picked up a Remington lawn mower, never been used, but dont make battery anymore, but i fitted a 40 ryobi, and modded the gut to except the ryobi battery, but ryobi has 2 T pins, the Remington has 1, i have reversed and get same outcome, so the controller has a signal wire, it comes from the plugs to the battery, in T2 the mower starts for 15 seconds, then stops, plus i have to put ryobi back on charger to reset battery...i think the answer is below, but i dont quit understand, i know temp sensor is important, but i want to bypass on controller.. most ryobi tools run only ( + and - ) only T for charging .. below is a comment from china to bypass brown and white wire ..
""The controller connection is defined in the introduction diagram. The detection signal line needs to be connected to the 10K resistance and the negative electrode, and the starting line is connected to two control switches. After the power is switched on, the starting line can start and run.""
I will have to check how it works on mine, but I see a couple options from the info you have. First, it sounds like they are saying to connect a 10k ohm resistor from the negative to the sensor wire on the controller to bypass the sensor. That is a great option. The other would be too get a Ryobi controller since it matches the battery. If the motor connects like mine it will connect to other brushless motors of similar size without a problem. But that adds to the cost. I can check mine, but any info I have is about the Ryobi controller and may not help you.
I have this big fanuc motor and I removed the encoder because I was going to use it in a go kart but when I powered it sensorless it just made weird sounds. If I gave it higher power (I was using 12 volts), would it run properly?
If it is this motor it should need at least 36v. However if you aren't using a controller on a brushless motor it won't work. It's not like a brushed motor that you can just put power to and it works.
@@oddjobsandrandomprojects I was using a 36v brushless motor controller. The motor spun slowly but I had to manual twist the shaft to get it going. I tried 24v and 36v but it only made weird sounds
@@Dipplers That is strange. What wattage is your controller. I've had good success with 750w-1000w controllers. Could also have a defective motor or something. Not entirely sure.
@@oddjobsandrandomprojects it seems to be 15amps and 180watts
@@Dipplers That may be the problem. I've been told that motor is 750w and while I haven't tested that it seems to be pretty accurate. The small controller may not have the necessary power to spin it properly. I'm not going to say I'm an expert of any sort, but that's my opinion.
Any idea what sprocket would work in there?
I haven't tested it with a sprocket. I originally had a V-belt pulley, but later started using a 3D printed cog belt pulley.
@@oddjobsandrandomprojects I gotcha. You said the shaft was a half inch correct? Also, is there a keyway on the shaft at all?
@@alexfrancis7093 That sounds right. I'm sure I measured for the video, but it's been a while. There is no keyway. Since it was designed to hold the blades they have a double D cut on the top that has a square washer to match. That stops the blade from spinning loose. I would have preferred an old school keyway.
Do you have a link to the higher power Husqvarna motor? Is it actually more powerfull than the ryobi?

The price for them has gone up since I bought mine. It has a higher rated power by about 150w, but I won't say I notice a difference. I think you are limited by what the battery can output. However it is easier to fit a pulley on, especially when you 3D print them. That was my main reason for the swap.
Will that motor power a go kart?
Depends on the gearing and desired speed. I'm my opinion you'd be better with the 48v motor I used in my scooter. I paid like $90-$100 new for it. If you change the controller you can use the 40v Ryobi batteries. Or if you have a 48v battery you can use the controller the motor came with. That motor is a little bigger and can run my scooter at over 30mph.
