ELECTRIC POWER TOOLS

摘要

An electric power tool, such as a hedgetrimmer, comprising: a plurality of blades (2) arranged for reciprocal motion relative to one another; an electric motor (3) having an output shaft (6); and a coupler (7) coupled to the blades (2) and arranged to convert rotational movement at an input of the coupler (7) into reciprocating relative linear movement of the blades (2), in which the output shaft (6) is directly coupled to the input of the coupler (7). A flywheel (9) may be provided on the output shaft (6), and the motor (3) may be a brushless permanent magnet motor, having an angular position sensor (14) such as a plurality of Hall Effect sensors (15) for the angular position of the motor rotor (10) or the output shaft (4).
