    Abstract: A blower includes a body, a motor, and a single fan configured to rotate in response to rotation of a motor shaft to discharge air through a discharge opening. The maximum rotational speed of the motor shaft is within a range of 50,000 rpm to 120,000 rpm. An area of the discharge opening is changeable by a user. The blower is configured to selectively operate in a first mode or in a second mode according to the area of the discharge opening. In the first mode, the maximum blowing force of the air discharged through the opening is within a range of 2.5 N to 5.0 N when the motor is driven at the maximum rotational speed. In the second mode, the maximum dynamic pressure of the air discharged is within a range of 30 kPa to 65 kPa when the motor is driven at the maximum rotational speed.

    Abstract: To reduce wasteful power consumption and noise generation, a control circuit drives a motor in response to a switch being turned on after a handle detector detects attachment of an auxiliary handle and a handle gripping detector detects gripping of the auxiliary handle, controls the motor to rotate at a predetermined first rotational speed in response to the switch being turned on with the attachment and the gripping of the auxiliary handle being detected, and controls the motor to rotate at a second rotational speed lower than the first rotational speed in response to a state of a load on a tip tool being unchanged for a predetermined period of time.

    Abstract: A blower includes a body having a main inlet opening and a discharge opening, a motor assembly housed in the body, and an auxiliary inlet opening. The motor assembly includes a case, a motor and a fan. The case has a first opening and a second opening. The motor is housed within the case. The fan is configured to rotate in response to driving of the motor to generate a flow of air passing the main inlet opening, the first opening, the motor, the second opening and the discharge opening in this order. A first space that communicates with the main inlet opening and the first opening of the case is formed within the body. The auxiliary inlet opening is configured to introduce the air from an outside of the body into the first space.

    Abstract: An electric power tool includes a housing, a fan, a tubular portion, and a rectifier. The housing houses a motor. The fan rotates in association with driving of the motor to generate a cooling air for the motor within the housing. The tubular portion is formed in the housing to house the fan. The rectifier is disposed to be opposed to the fan in an upstream side of the cooling air. The rectifier is divided into an inside and an outside in a radial direction of the tubular portion, the outside in the radial direction is formed of the tubular portion, and the inside in the radial direction is formed of a baffle plate assembled to the housing.
