POWER TOOL
Document Type and Number:
WIPO Patent Application WO/2015/182507
Kind Code:
A1
Abstract:
In order to provide a power tool such that the capacitances of noise-suppressing film capacitors can be increased without increasing the diameter of a handle section, the housing (1) of the power tool comprises: a body section (2) that houses a brushless motor (10), a striking mechanism part (20), and a portion of an output part (30); a handle section (3), one end of which is connected to the body section (2); and a storage section (4) that is formed on the other end of the handle section (3). A pair of film capacitors (42a, 42b) for removing noise generated from an inverter circuit are mounted on a capacitor substrate (42c) and housed side by side inside the handle section (3). The film capacitors (42a, 42b) are connected in parallel with each other, thereby providing a capacitor having a larger total capacitance than before.
