摘要： In order to make a displacement type compressor be able to reliably start without increasing an outside diameter dimension of the compressor while using a self-start synchronous motor having high energy efficiency, the displacement type compressor according to the invention includes the self-start synchronous motor which starts as an induction-motor and performs synchronous operation by performing synchronization pull-in almost at a synchronous rotational frequency, a compression part having a compression chamber which compresses a working fluid, and a hermetic container which houses the self-start synchronous motor and the compression part. The displacement type compressor is provided with a start load reducing means which reduces a load of the compression part at startup and is-placed at the compression part in the hermetic container.

摘要： A displacement type compressor includes a compressing mechanism section for performing a compression, a motor for driving the compressing mechanism section, and a crankshaft adapted to be driven in rotation by the motor to rotate the compressing mechanism section. The motor includes stator cores and having claw-type magnetic poles formed of a magnetic powder and circumferentially arranged in alternately meshed states, and annular coils and wound in a toric shape around the claw-type magnetic poles. Thus, the displacement type compressor is capable of being at a high speed and has a reduced size.

摘要： The invention provides a motor comprising a stator and a rotor. The stator core includes a laminated stator core made of laminated stator core plates in which straight cut surfaces are formed on a circular outer peripheral surface of the laminated stator core plates. The straight cut surfaces of the laminated stator core plates are circumferentially displaced every predetermined laminated stator core plates so that the straight cut surfaces are uniformly distributed in an axial and a circumferential direction of the laminated stator core. Therefore, a flow passage for lubricating oil is ensured, while local magnetic saturation of the stator core is dissolved and a cogging torque and an induced voltage waveform distortion rate are improved.
