Puny motor in Ryobi cordless chainsaw

[Donald]

So the motor is broken in my Ryobi cordless chain saw. I took it apart to test the motor. I have +20V to the motor and if does not run.

I think this is a puny size motor for a 10" cordless chainsaw. Maybe I am expecting too much. It's a Ryobi and not a Stihl.

Here is the odd thing. The bare tool is $159. A replacement motor and switch wiring is $32 plus shipping. That seems low as there is a bar, chain, motor and a bunch of plastic.

Now maybe the $32 price is an old price. The motor is marked backordered or special order. Maybe the motor has stayed at its original price from several years ago and will just never ship.

I would have expected the parts price for the motor to get 1/2 the cost of the bare tool.

Most likely a standard size motor.

Bar + chain + motor + plastic + profit. 30 + 30 +30 + 30 + 30 = 150?

Those little permanent magnet motors have more power than you can imagine when they are multiplied by a gearbox for torque.

I had to order a ryobi chain tensioner once, it seems like it was engineered with glass, took 8 weeks, also backordered.

More than likely the same motor used in the past at a lower voltage.

Can you see the brushes in the back of the motor? One of them might be stuck or damaged.

I have a 40v Ryobi arborist saw and couldn't be happier with it. Those small motors are one of the "good" things about things constantly improving, as they are amazingly powerful, out of all proportion to their size.

Until the break and then what?

how much use did you get out of it before it broke?

 

[Zee09]

I no longer buy anything Ryobi
Find there stuff loud, vibrates too much, and short lived.

their newer HP line is decent to good, some of their other gear can be budget.

I would guess 5 years on and off. Maybe 10 hours or less total. Never sharpened the chain that I can remember. I had gas chainsaws in addition until recently.

I have one of those 18v saws and it’s lasted longer than it should. It’s been a good little saw. I looked at the 40V and the forward handle seemed flimsy to me, especially considering the weight of the saw. Didnt buy it. The newer 18V with the better brushless motor might be the sweet spot of youre considering ryobi. It’s definitely consumer grade, but generally serviceable.

I've owned a Ryobi One+18V brushless saw for about 5 years now. I use it more than my 16" 2 stroke Echo at my cabin. Gone through 4 chains now and 1 bar and this thing has never had any issues.

Many of the battery chainsaws say that they can do things that they really can't. For example they say they can make 75 cuts through a 6" log. Maybe....but I bet they are using wood from a balsa wood tree.

I'd love to see the motor inside a top of the line battery powered Stihl or similar.

For the record I am in the market for a pole saw to trim branches that are starting to hang low or are getting in the way of things. This is about as much as I would expect from an electric chain saw. Considering I am only going to use it once every couple of years on a couple dozen 2-3" branches I am thinking of getting a Harbor Freight model. If it dies....it dies.

Those motors are a common size, such as 555 or more likely a 775 size. They are available in many RPM and torque and voltage configurations. A little research and maybe you could find a similar motor from a DC powered RC car or similar with mo powa.

You could say that about any machine. Brush motors are a wear item that generally isn't going to last as long as the rest of the tool.

A few years ago I bought a Hyper Tough 10" from Walmart for $39, and it's been great. It punches way above its weight. I've used it heavily and mercilessly, including cutting roots and burying the bar/chain in the dirt. Just for kicks, I recently bought a new chain, because the old one was so rusty. Personally, instead of buying a motor for that ryobi, I'd be looking for a new, cheap, saw.

Trying not to get too many battery systems. I have mostly Milwaukee M18/M12 and a few Ryobi 18V.

Maybe a small Milwaukee brushless M18 if this Ryobi motor breaks again.

Whatever you get please get some extra, quality chains for it and keep it well oiled if it doesn't have an internal oil pump.
