Japanese Patent JP2009002352
Kind Code:
A
Abstract:
To provide a compressor for preventing large noise and vibration when run.
A coil 520 of a stator 5 in a motor 3 is a concentrated winding. Inside a cylindrical rotor core 610 of a rotor 6, a small diameter part 610a and a large diameter part 610b are provided. A shaft 12 is fixed to the small diameter part 610a, and a bearing 7 is inserted to the large diameter part 610b. The shaft 12 is set to overhang by the bearing 7. A compressor element 2 and the rotor 6 are combined through the shaft 12 to form a one-body structure 8. The specific vibration number of the one-body structure part 8 is greater than 5 times the maximum rotation number when the compressor is run.
