Title:
AUXILIARY MAGNETIC BEARING ROTOR HEAT DISSIPATION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/128632
Kind Code:
A1
Abstract:
Provided is an auxiliary magnetic bearing rotor heat dissipation structure, comprising a motor rotor (1), a radial magnetic bearing seat (2), a rotor silicon steel sheet lamination (3), a first pressing plate (4) and a second pressing plate (5), wherein a matching surface (11) is arranged at the front part of the motor rotor (1), the first pressing plate (4) is cushioned on the inner side of the matching surface (11), the rotor silicon steel sheet lamination (3) is sleeved on the matching surface (11) and positioned on the outer side of the first pressing plate (4), the second pressing plate (5) is connected to one side of the matching surface (11) in a sleeving manner and abuts on the outer side of the rotor silicon steel sheet lamination (3), the motor rotor (1) is suspended in the middle of the inner side of the radial magnetic bearing seat (2), and a turbulent flow fin (51) is arranged on the outer side of the second pressing plate (5).
