Document Type and Number:
WIPO Patent Application WO/2012/041259
Kind Code:
A8
Abstract:
A variable capacity compressor assembly (20) configured for variable capacity modulation includes a housing (30), with a compressing mechanism (22) and a driving mechanism (24) disposed within the housing. The compressing mechanism includes compressing members (54, 56) that are shiftable relative to one another between loaded and unloaded states. The driving mechanism includes a line-start brushless permanent magnet motor (26). The line-start brushless permanent magnet motor includes a plurality of permanent magnets (102) that are mounted on, and extend generally axially along, a rotor core body (90) of the motor. Using the motor may reduce manufacture cost, maintain conveniently, and increase reliability.
