Claims8
An electric compressor that has an electric motor and a compression mechanism, which are accommodated in a housing, the compressor comprising:
- a chamber for accommodating the electric motor and the compression mechanism;
- and
- a shaft that functions as the output shaft of the motor and the drive shaft of the compression mechanism.
An electric compressor that has an electric motor and a compression mechanism, which are accommodated in a housing, the compressor comprising:
- a chamber for accommodating the electric motor and the compression mechanism;
- a shaft that functions as the output shaft of the motor and the drive shaft of the compression mechanism;
- wherein the compression mechanism includes:
- a rotating member that rotates integrally with the shaft;
- a plurality of cylinder bores formed in the housing;
- a plurality of pistons, wherein each piston can reciprocate in one of the cylinder bores;
- a cam plate that can slide on and incline relative to the shaft, wherein the cam late is coupled to the pistons and to the rotating member, wherein the cam plate converts rotation of the shaft into reciprocation of each piston, and wherein the inclination angle of the cam plate is adjusted to change the stroke of each piston;
- and
- wherein the electric motor includes a rotor, wherein the rotor has an iron core that is formed by laminating a plurality of steel sheets and a pair of rotor ends, and wherein the rotor ends are located at the ends of the iron core to fix the core relative to the shaft.
