Title:
MAIN ELECTRIC-MOTOR FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/163264
Kind Code:
A1
Abstract:
In the present invention, an exhaust port (42) for discharging air that flows in from an intake port (21) is formed in an end surface (41) that is far from a fan (10) and that is orthogonal to the direction of a rotor shaft (3) of a first bearing box (4). A flow passage (20) is formed between a frame (2) and an outer peripheral surface of a cylindrical part (43) of the first bearing box (4) connected to the end surface (41). The value obtained by dividing the distance from the outer peripheral portion of a blade (11) of the fan (10) to the exhaust port (42) by the outer radius of the blade (11) is at least a threshold value.
