Document Type and Number:
WIPO Patent Application WO/2015/188672
Kind Code:
A1
Abstract:
A stator used for a motor, the motor and a ventilation cooling method for the motor. The stator comprises concentrated windings (11, 12, 13), and at least two wedge blocks (41-48) are arranged at the gaps between the adjacent concentrated windings (11, 12, 13). The at least two wedge blocks (41-48) are distributed on the concentrated windings (11, 12, 13) in a staggered manner to form a first ventilation path. Therefore, the concentrated windings (11, 12, 13) can be cooled effectively, the concentrated windings (11, 12, 13) are effectively constrained in the circumferential direction by means of the at least two wedge blocks (41-48), the service life of the motor is further prolonged, and the reliability of the motor is improved.
