Abstract

The invention relates to a high-speed electric motor, e.g. for domestic appliances, especially for a vacuum cleaner, with a rotor fitted with a motor spindle and a stator, in which a fan is flanged to the motor spindle to cool the motor and, in a vacuum cleaner, for instance, to provide the suction power and in which the rotor and stator are fitted in a motor housing (5) and at least part of the cooling air flows along the outside of said housing (5). In order to provide a high-speed electric motor where at least part of the cooling air flows around the motor housing and which is characterized by an improved diversion of the cooling air flow, it is proposed that the cooling air be caused to flow in a helical path outside the motor housing.
