Abstract: An electric compressor including: a rotating shaft configured to drive a compression mechanism; a rotor configured to have a rotating shaft through-hole into which the rotating shaft is inserted; a cover configured to cover a longitudinal end of the rotor; and a stator configured to be installed on a radially outer side of the rotor. A plurality of slots into which a permanent magnet is inserted is formed to be spaced apart from each other in the rotor in a circumferential direction of the rotor. A cooling hole is formed in both ends of the slot, and the slot and the cooling hole are spatially separated. Refrigerant flows into the cooling hole and cools the permanent magnet. Accordingly, it is possible to improve the cooling performance of the permanent magnet.

Abstract: A varnish impregnation method of a stator coil winding. The varnish impregnation method includes: a first step of maintaining an inside of a vacuum chamber to be in a vacuum state; a second step of injecting varnish into a slot of a stator core through a varnish supply hole formed in a lower housing of the varnish impregnation device; a third step of causing an air pressure within the vacuum chamber to come to equilibrium with an external air pressure, discharging the varnish from the vacuum chamber, and transferring the varnish again to the varnish storage tank; a fourth step of stopping the operation of the air pump when the discharge of the varnish from the vacuum chamber is completed; and a fifth step of separating the stator from the varnish impregnation device, withdrawing the stator from the vacuum chamber, and curing the varnish in a curing device.

Abstract: A compressor that includes a casing, a compression mechanism provided inside the casing to compress a refrigerant, a rotary shaft transmitting a rotational force to the compression mechanism from a drive source provided outside the casing, a clutch connecting the drive source and the rotary shaft by a magnetic force generated when electric power is applied to the clutch and disconnecting the drive source and the rotary shaft by losing the magnetic force when the electric power applied thereto is cut off, and a rotation measurement means for receiving the magnetic force from the clutch to measure a change in magnetic flux according to the rotation of the rotary shaft and measure a rotational speed of the rotary shaft. Thus, it is possible to measure the rotational speed of the rotary shaft without including a permanent magnet.
