It helps to have some sort of electrical training. When I got my education in electrical technology the teachers were all old radio guys and we were usung tubes. my experiance with computer chips was limited to the Zilog 8080.What I’ve learned from this short study in brushless motor and electric speed control configurations is that many of these units can be modified, as mine will be very soon, with a polarity reverse switch for dual direction operation. It’s really as simple as adding the proper switch with the right jumpers in the right configuration. I’ll tell you what though, get a heavily sensored motor like my Ryobi and go get out the multi meter and cross off two days off your schedule to test each of the 36 possible configurations of sensor wires and phase wires.

Thanks, I’ve been digging pretty deep into brushless motor electric theory and bothering engineers on an electric forum lol. If you didn’t notice, I tried super hard to make my Ryobi bi-directional but the electronics were much more complex and very optimized for the specific rotation direction from the factory. I was prepared to reroute the hall sensor wires to correspond with the changed phase wiring but I was advised that there’s even more going on in the Ryobi system preventing one from just meticulously reversing every wire. The ego is a more like a carbureted engine compared to a efi system lol.Good job.
I’ve definitely crash coursed myself in brushless motors over the last month.It helps to have some sort of electrical training.

That’s the trimmer I use. Started out as a backup to my gas stihl trimmer. But I always found myself reaching for the battery operated stuff. Same goes for my blower. Just can’t beat the convenience.I spent hours researching and attempting to reverse my Ryobi powerhead but it was too heavily sensored and optimized for uni direction so I put it back together and set my crosshairs on the Ego. I really wanted the Ryobi to reverse because the extremely precise throttle control but that same control prevented me from achieving my goal.
The Ryobi has a hall’s sensor setup while the Ego is sensor less which makes it super easy but it doesn’t have the control I’ve become accustomed to, alas. Electrical theory states that basically and non sensored motor can be reversed by switching two of the three main phase wires and it held true for the Ego electronics, sweet. I now have a straight shaft trimmer with clockwise rotation from the operator perspective 💪🏼💪🏼

Hurryup electric removes himself from any liability or damage to powerheads or any electrical devices caused by following my amateur modifications. This will definitely void any warranty, for entertainment purposes only.
This ^^^ is why I'm going to remain on the sidelines for quite a while on battery op equipment. But neat thread. When you reach perpetual motion with your rebuild please post LoL. Seriously good job on the work.Ok, so how about on average properties. 15 minutes? 30? I had an Echo 58v and it lasted 4 lawns.
Most geniuses throughout history were ridiculed but I’ll go down in lawnsite history as a street legend for my innovations 😎You do realize that you have lowered yourself to BELOW "not a pro" now in the eyes of the holy LawnSite, right?
That's awesome. Glad it worked out!
I’m through the math and misc prerequisites at the local two year college. The very next classes will be the actual electrical engineering technician courses. I evaluate every now and then what direction I’m heading and if it’s a realistically happy path. I can always scale up or down my operation to accommodate finishing school. I can see myself loading down in the January to April semester and then switching back to business owner if I want.
It should be interesting to people besides myself some of the cliffs notes I’m providing. I mean I’ve been using Ryobi stuff for three seasons and getting the occasional jokes about it but start digging around the inside and realize it’s actually a fairly well engineered unit.You are also giving up the goods on why Ego stuff probably isn't worth the high mid to high prices.
