WIPO Patent Application WO/2019/058647
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a highly durable all-weather motor capable of maintaining motor performance in such a way that the degradation of the motor performance is prevented by enhancing a heat dissipation property and the intrusion of foreign objects is prevented by enhancing dust-proof and drip-proof properties. The problem is solved as followed. A rotor (14) has: a rotating case body (4) covering the outer circumferential side of a stator core (12) and both end sides of a bearing housing (11) in the axial direction, having an intake opening portion (4e) on one end side in the axial direction, and having a discharge opening portion (4f) on the other end side in the axial direction, said intake opening portion (4e) taking in air in the axial direction, said discharge opening portion (4f) discharging air in the radial direction; and a fin (17) provided on the inner surface of the rotating case body (4) at the other end in the axial direction. The intake opening portion (4e) and the discharge opening portion (4f) are each covered with a water-shedding filter material (18) having a predetermined opening size.
