Embodiment approach

[0042] According to one embodiment, the electronic control board is integrated in the operating and support handle 5 of the chain saw.

[0043] A power supply cord 12 connected to the tool - preferably to the lower part of the handle 5 - enables the motorization of the portable chainsaw to be connected to a direct current power supply, which may consist of a separate portable rechargeable battery 13 which is placed in use in the backpack 14 of the wearer or carried by his waist belt.

[0044] According to another embodiment, an electronic circuit board for control or management is integrated in the battery 13 .

Abstract

The chainsaw has a power source enclosed in a case (1), and a cutting device including an inverted tooth chain (2) that is engaged with a drive pinion. The source assures the rotation of the pinion, and has an electronically-switched and controlled direct current brushless electric motor (4) that is provided with magnet rotors. A carrying or operating handle (5) is arranged above the pinion and is oriented perpendicular to a longitudinal axis of a guide bar (3). The pinion is mounted coaxially to an axis of the rotor of the motor.

Description

technical field [0001] The invention relates to a portable electric chain saw. Background technique [0002] Portable chainsaws, also known as log saws (cut saws), are commonly used to perform pruning work or forestry work, such as felling, pruning and chopping of trees. [0003] This relates to motor-driven tools for cutting wood, consisting essentially of an integrated small unit comprising a power source, a cutting system and a handle arranged and constructed so that both hands can be used during the work Hold on tight and hold on. [0004] More often, the power source consists of a heat engine, which means its operation is noisy and polluting. [0005] Portable section saws are also known whose power source consists of a DC brush motor or an AC brush motor with a power of between 400 W and 2500 W and which operates relatively quietly and with little pollution. [0006] However, regardless of the nature of the power source (thermal or electric), the chainsaws currently...
