Abstract

The present invention provides a handheld electric tool and a motor assembly for a handheld electric tool. The handheld electric tool of the present invention comprises a housing, a working member, a motor and a motor support. The motor support comprises a first part positioned at a far-side end of the motor and fixedly connected to the housing, and a second part extending from the first part into the interior of the motor and fixedly connected to a stator of the motor. The second part is provided with a first through-hole for a rotor shaft of the motor to pass through, and an output end of the rotor shaft extends through the first through-hole and drives the working member to move. The handheld electric tool provided in the present invention can prevent excessive transmission of motor vibration to the housing, and can pump fluid through the motor to cool components in the housing. Furthermore, the motor assembly of the present invention has an ingenious layout, making the machine as a whole smaller and more lightweight.
