Features: 【HIGHLY EFFECIENT CUTTING WITH 1 BATTERY】battery powered cordless chainsaw takes about 20 seconds to cut a log with a diameter of 12in (the specific value varies with the actual size and hardness of the wood). This electric saw is very suitable for wood cutting, trees branches pruning, gardening. 【ONE HAND USING】 This mini electric chainsaw using weight just about 3.7lbs. Woman can easily control and use it, it's not tiring for a long working time. 【POWERFUL DYNAMIC SYSTEM】This cordless chain saw battery-powered wood cutter adapt high-quality guide chain which has undergone a deep quenching process ensures smooth cutting. The wood tooth design can make the chain saw stuck on the branch, cutting efficiency is higher and faster. 【EASY INSTALL & OPERATE】 The whole chain saw has been installed, you just need to simply use the wrench in the package to turn the screw to adjust the tightness, and finally tighten the screw. (You don’t need to install the chain separately) 【ERGONOMICS DESIGN】 The integrated guide plate dissipates heat quickly and is very resistant to falling and abrasion. With non-slip handle design, the grip is very comfortable. The chain saw switch can adjust the speed according to the strength, and you can adjust the cutting speed you need according to the operating conditions.

What is the Difference Between Brushed and Brushless DC Motors? A brushed DC motor uses a configuration of wound wire coils, the armature, acting as a two-pole electromagnet. The current's directionality is reversed twice per cycle by the commutator, a mechanical rotary switch. This facilitates flow of the current through the armature; thus, the electromagnet’s poles pull and push against the permanent magnets along the outside of the motor. The commutator then reverses the polarity of the armature's electromagnet as its poles cross the permanent magnets' poles. A brushless motor, by contrast, utilizes a permanent magnet as its external rotor. In addition, it uses three phases of driving coils and a specialized sensor that tracks rotor position. As the sensor tracks the rotor position, it sends out reference signals to the controller. The controller, in turn, activates the coils in a structured way – one phase after the other.

What are the Advantages of Brushed and Brushless DC Motors? ▶ Brushed 1. Low overall construction costs; 2. Can often be rebuilt to extend life; 3. Simple and inexpensive controller; 4. Controller not needed for fixed speed; 5. Ideal for extreme operating environments. ▶ Brushless 1. Less overall maintenance due to lack of brushes; 2. Operates effectively at all speeds with rated load; 3. High efficiency and high output power to size ratio; 4. Reduced size with far superior thermal characteristics; 5. Higher speed range and lower electric noise generation.
