Abstract
A screw compressor (12) includes a casing (20) having a suction port and a discharge port, a male rotor (28) rotatable relative to said casing about a first axis (A), a female rotor (30) rotatable relative to said casing about a second axis (B), and a magnetic gear system including a first magnetic gear (60) associated with said male rotor and a second magnetic gear (62) associated with said female rotor. The first magnetic gear and the second magnetic gear are positioned such that a magnetic field of said first magnetic gear interacts with said second magnetic gear to drive rotation of said female rotor about said second axis.
