Document Type and Number:
WIPO Patent Application WO/2018/163643
Kind Code:
A1
Abstract:
Provided is a portable electric tool having a satisfactory weight balance in a configuration in which a reactor is provided in a current pathway of a motor. A portable cutting machine 1 comprises: a motor 6; a motor housing 11 accommodating the motor 6; a saw blade 16 rotated by the motor 6; a handle housing 12 connected to the motor housing 11; a rectifier circuit which converts alternating current into direct current and supplies the direct current to the motor 6; electric field capacitors C2, C3 which smooth the output current from the rectifier circuit; and a reactor L2 provided in the current pathway of the motor 6. The motor 6 and the saw blade 16 are located on mutually opposite sides of a virtual plane P which passes through a central axis of a handle portion 12b and which is parallel to a direction of operation of the portable cutting machine 1. The reactor L2 is located on the opposite side of the virtual plane P to the saw blade 16.
