Title:
COMPRESSOR AND MOTOR THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/098340
Kind Code:
A1
Abstract:
A motor and compressor which relate to the technical field of cooling devices. The motor comprises a housing (1) and a rotary shaft (2) and rotor (3) that are mounted on the housing (1); the rotor (3) is sleeved on the rotary shaft (2), and the rotor (3) is provided with a cooling through hole (31), the cooling through hole (31) penetrating the rotor (3) along the axial direction of the rotor (3); the rotary shaft (2) is provided thereon with flow guide grooves (21), and the flow guide grooves (21) are adaptively provided with coolant supply ports (41); the flow guide grooves (21) communicate with the cooling through hole (31), and the flow guide grooves (21) are a helical structure. Under the common action of the rotating rotor (3) and helical flow guide grooves (21), coolant flowing out from the coolant supply ports (41) is more easily introduced into the cooling through hole (31), and as a result, the cooling effect of the rotor (3) in the motor is improved.
