Cordless electric chainsaws have a variety of electric motors that can range from 8 to 40 volts and depending on the length of its cutting bar which may measure from 12 inches up to 20 inches. Most electric chainsaw motors have a step-up induction circuit that drives its 2 phase motor which could have an optimum operational horsepower of between 2.5 to 4 horsepower and since its power is provided by its battery pack, it can fully sustain a running time of up to 30 minutes before changing battery packs. As far as the electrical circuit is concerned, there are newer models of cordless electrical chainsaws today that have reciprocal charging systems that return a substantial amount of energy back into its Lithium-Ion battery while you use it.
This enables battery powered chainsaws to run for a more prolonged period of time which optimizes its efficiency with regard to getting the most out of its battery pack. Most cordless electrical chainsaws use a 2 phase electric motor which enables it to run within two speed settings from low to high RPM. Having a two-phase motor gives electric chainsaws the ability to run at idle speeds of 2,500 RPM to as high as 5,000 RPM which is ideal to enable it to cut down hardwood. Its motor is similar to that used by power tools such as angle grinders and precision hand drills. Most cordless electric chainsaws use carbon brush contact points that draw power from its battery pack and into the motor’s field winding through its armature.
Improvements in electrical motor designs through years of innovative research and development has greatly increased the efficiency of modern electrical motors, enabling manufacturers to make smaller yet powerful electrical motors that can be used in electrical chainsaws as well as other power tools. To further increase motor efficiency, sealed ball bearings with industrial grade lubricants that were encased during assembly give cordless electric chainsaw a longer motor life and lower maintenance frequency. Lubrication is considered as one of the most important aspects in keeping cordless electric chainsaws in perfect running conditions along with making regular motor checkups that include evaluating the condition of the carbon contact brushes.
Limitation in operational time is the most common characteristic among cordless electric chainsaw since its power depends on the capacity of its Lithium-ion battery pack. Cutting speed can be a bit slower since these type of cordless chainsaws do not have the same power and sustainability as that of gas-powered chainsaws when it comes to speed. You will also have to consider that you would have to change battery packs every now and then to enable you to get through all of your cutting tasks at hand. Again, you will also have to determine the amount of wood that you will be cutting down since cordless electric chainsaws can efficiently undertake cutting down branches with sizes of about 3 to 4 inches thick with a maximum amount of 400 times in one charge (40 volt lithium-Ion battery pack).
Unless stated so by the manufacturer, some cordless electric chainsaws can operate under any incremental weather conditions that can be safely used without any risk of you incurring electrical shock. Although not all portable chainsaws have this quality, it is best to inquire with the manufacturer before deciding on purchasing one for outdoor use.
Maintaining a cordless electric chainsaw is much more easier than that of a gas-powered chainsaw since electric chainsaws have very few parts that you have to maintain such as the carbon brush contact point, the electric motors lubrication, including the bearings and the Lithium-Ion battery pack. As compared to gas-powered chainsaws that have a lot of moving parts since it has a two-stroke engine, maintaining a cordless electric chainsaws is a walk in the park.
Ease of use is another advantage that most people are getting to like about these type of chainsaws compared to gas-powered ones when it comes to safety issues. Admittedly, gas-powered chainsaws are really quite hard to use, even for professionals since there is the possibility of engine malfunction such as the carburetor lever getting stuck which could lead to the engine to run wild and out of control. Having to contend with the engine heat is also one issue with gas-powered chainsaws since it uses a combustion engine, using a cordless electric chainsaws is much safer since its electric motor does not even come to a quarter to the heat produced by gas-powered chainsaws.
Most if not all cordless electric chainsaws have a built-in safety switch which stops the flow of power from the battery to the motor once you let go of the handle grip. It also has a secondary safety which disengages the main chain drive either magnetically of mechanically. Some cordless electric chainsaws are even considered lighter than their gas-powered counterparts even with their battery packs on and since these chainsaws have more impact resistant plastic parts, using them is more convenient compared to conventional gas-powered chainsaws with regard to with weight and handling.
With regard to handling, people who have gotten to prefer using cordless electric chainsaws over gas-powered ones find the convenience of handling electric chainsaws with ease since they will not have to struggle with the stress of having to deal with body fatigue which is common with people who have used two-stroke gas-powered chainsaws. Cordless electric chainsaws run more smoothly and more quieter than gas-powered chainsaws and since they use an electric motor that runs on a consistent cycle and since it uses no pistons, there is very minimal vibration and heat, giving you a much more easier means of using it. Added to this, cordless electric chainsaws have a very low operating noise level which ranges from between 86 to 90 decibels which is about the same with that of the noise level produced by a food processor.
