Cord to Cordless Chainsaw Conversion | RYOBI CS-2501

In this video, I converted an electric chainsaw to a battery chainsaw. The original power tool is made in Japan, it runs AC 110V that can't be used in my location 220V. I want to use this chainsaw for Durian pruning in my farm, so the battery is the best choice for me. It isn't powerful like a gasoline chainsaw, but I can cut some branches easily.
About the dc motor
High-power high-speed motor, motor diameter 60mm, similar to the 9 series motor, double ball bearings at the front and rear, built-in cooling fan blades, 12-pole motor rotor, power exceeds 885/887 motor, the carbon brush is a high-current high-copper compensation type. 18V requires more than 80 watts even when no-loaded, so a high-current power supply or a power-type high-current battery is required to drive it, or it can be slow-started with a DC motor PWM speed regulator. This can reduce the instantaneous high current impact of the motor starting on the power supply.
The motor test speeds at 12V, 18V and 24V are as follows:
- 12V voltage, no-load current 4A, no-load speed 9200 rpm.
- 18V voltage, no-load current 4.5A, no-load speed 14000 rpm.
- 24V voltage, no-load current 5.3A, no-load speed 19000 rpm.
The motor weighs 760 grams.
The motor was originally used in high-power power tools. The dynamic high-power motor has a maximum power of about 800W compared to similar motors, and the peak power exceeds 1000W.
I hope you find this video useful and enjoy it!
Furthermore, I am happy to receive feedback, suggestions to improve myself.
Thank you very much for choosing to watch my video!
Have a nice day

Good job mister beautifully restored well done

[@gear_show]

Thank you!

[@glloq75]

I find that the chainsaw lacks a little power when cutting, a 24V version would perhaps be more efficient, otherwise very good work

[@alexandres8846]

yes but.. battery standard 18volt or 36volt. 24vdc battery is exeption for only kobalt or flex tools this tools no popular brands.

[@gear_show]

Yes, you're right, 24V will be good for this motor.

Nice conversion, wish my electric was converted.

[@gear_show]

You can follow what I'm doing, thank you!

[@Sadnlove]

Love watching your videos! Could you do a tutorial on how you rewind the motors and how you determine what’s a good voltage to convert too?

[@gear_show]

Thank you so much! You learn it by watching my work carefully. Actually, I learn winding by watching the original structure of the armature. I disassemble 12V, 18V armature by counting the coil turn and copper size. 12V armature 5 turns, 18V 8 turns, torque depend on number of turns, power depend on the copper wire size.

[@elonwhite6628]

A single battery chainsaw will cut through its power quicker than wood, you should double up the battery and use a 40v motor

[@gear_show]

Yes, I used to do that, it is heavy. Anyway, thank you for sharing!

Hi, what's the name of the cordless screwdriver you use to disassemble all those machines

[@DinizAriel]

Does heating black plastic really work? Everytime I try this, the plastic gets gray again in a few months

[@myoccultreality]

My brand new hammer drill machine is wobbling too much... Even normal drill mode, Any reason why?

[@aizunomnom8556]

Did you just connect the motor onto the pushbutton? Not adding any relay or mosfet?

@@gear_show you can convert the 18V from the makita battery with a DC-DC buck converter into 95V, use 2 of them parallel and you have 190V enough to run it without changing the motor
