Static cooling electric saw that includes a cutting chain (2) fitted to rotate around a drive pinion gear and an oblong chain guide (3), and an electric motor (4) driving said chain by means of said pinion gear, characterised in that the electric drive motor of the cutting chain comprises a brushless direct current motor (4), enclosed in a crankcase (5) formed by at least two parts (5A, 5B) and made of light metal alloy, with a surface with which the motor is in contact, so that the static cooling of said motor is facilitated. |
