Abstract

An electric tool may include a motor housing and a motor disposed within the motor housing. The motor has a stator fixed in position relative to the motor housing and a rotor rotatable about a motor axis. Cooling air can flow within the motor housing across the motor in a direction substantially parallel to the motor axis. A baffle may be disposed within the motor housing for regulating the flow of cooling air across the motor. At least a part of the baffle may be positioned within a range of a length of the stator with respect to the axial direction of the motor axis.
