Abstract: An electrically powered blower configured to be capable of fully cooling its motor and of efficiently cooling a power element in a drive circuit without involving such need as of increasing the size of a fin of a separate heat radiator, contributing to miniaturization of electric equipments. The electrically powered blower includes a power element (10) provided in a drive circuit (9) and connected to a motor casing (B). Since the motor casing (B) serves as a cooling fin for the power element (10), a great effect on cooling can be obtained, and a heat radiator separate from the motor casing is not required, thus contributing to miniaturization of electric equipments.

Abstract: A compact and light electric blower which is improved in wiring cooling capability without reducing the airflow efficiency. The electric blower includes a spool attached to end surfaces of a field core fixed to a motor frame of which outer periphery portion is in an approximately cylindrical shape, and field wiring each wound across the field core and the spool, wherein a gap capable of passing air is formed between the coil end between slots of the field wiring and the field core, and each spool is provided with a wall surface which narrows the airflow section formed between the field core and the motor frame while forming a periphery portion of the field wiring.
