Abstract
A motor driven compressor has a motor and a compressing mechanism connected to the motor through a rotary shaft, which is located within a housing, and an offset of phase is set between a stator and a rotor. The rotor is mounted to the rotary shaft, allowing the rotor to rotate so that it may be magnetized. Further, the motor driven compressor has a driving member driven together with the rotary shaft, a communication gas hole formed within the housing and extending from a suction port to a discharge hole, and a mark positioned along a radial axis on a first end surface of the driving member. The mark is used for setting the offset of phase between the stator and the rotor on the basis of a mark, by positioning the mark opposite the suction port. Accordingly, the motor driven compressor has a structure, which allows the rotor to be readily magnetized and may reliably set the offset of phase between the rotor and stator for magnetizing the rotor.
