Document Type and Number:
WIPO Patent Application WO/2019/134373
Kind Code:
A1
Abstract:
A compressor and a refrigeration device. The compressor (1) is used with a refrigeration device, the refrigeration device comprising a connection assembly and a frequency converter (10) that is connected to an end of the connection assembly; the compressor comprises: a first housing; a permanent magnet motor (20), which is disposed within the first housing and which is connected to the other end of the connection assembly; the critical speed of rotation of the permanent magnet motor is n0, and the pole number of the permanent magnet motor is P; when windings of the permanent magnet motor are connected in a star shape: the bus voltage of the frequency converter is Udc; the no-load counter-electromotive force coefficient of the permanent magnet motor is E0; when the preset speed of rotation of the permanent magnet motor is n1, the direct shaft inductance of the permanent magnet motor is Ld, and the output current of the frequency inverter is I1; the relationship between E0, P, I1, Ld, n1 and Udc satisfies: (E0-P×I1×Ld)×n1≥0.6Udc, wherein n1
