Although they don’t have the power of a gas saw, cordless electric chainsaws are lighter, quieter, and simple to start. Plus: no fumes! Perfect for pruning, yard cleanup, and light cutting.

A large motor costs more and increases the weight of the whole unit. Whereas a DC motor provides portability due to its small weight and size. There are various types of these motors, the one used here in this project is a 775 DC motor.
For only eight dollars you can get a 775 DC motor online. Depending on the configuration of the motor that you buy, it can spin from 3500 to 7500 RPM which is good enough for the circular saw that you are making today.
The Chainsawr saw, as demonstrated in the video , has enough power in it to cut the wood easily. The 775 motor is one of the most favorite components of many DIY enthusiasts, and for a good reason.
