Abstract
A power tool, for example, a portable circular saw, includes a fan, a motor configured to rotate the fan, an output part or shaft driven by the motor, a motor housing that houses the motor, a grip housing connected to the motor housing, a trigger associated with the grip housing, and a brake member configured to brake a rotation of the motor, the brake member being mounted inside the grip housing. The brake member may be a resistive element of a rheostatic braking system. The housing and fan are configured such that cooling air is directed to cool the brake member.
