Abstract

PURPOSE:To improve the air efficiency and cooling efficiency by providing multiple convexes axially, which constitute the vibration flue, along the outside circumference of a bracket. CONSTITUTION:Multiple convexes 8 are provided axially on the outside circumference of a bracket 5b which project outwards. A ventilation flue 7 is formed by this convex 8 and a stator 1. When the suction air is sucked into the inside of a commutator motor through a louvre 6a of a bracket 5A, it passes through the air gap between the stator 1 and a rotor 2 as well as through the ventilation flue 7 between the stator 1 and a bracket 5b and exhausted from a louvre 6b of the bracket 5b. In this way, by providing multiple convexes on the outside circumference of the bracket 5b, the ventilating cross section is so extended that the air efficiency and cooling efficiency can be improved.
