The present disclosure provides an electric compressor comprising a main housing, a motor part disposed in the main housing and comprising a stator comprising a rotor accommodating portion and a rotor rotatably disposed in the rotor accommodating portion, a compression part rotatably connected to the motor part, and an inverter part electrically connected to the motor part. The motor part is disposed in a motor room formed inside the main housing, the stator comprises a plurality of insulating protrusions protruding from an outer circumferential surface of the stator, and the plurality of insulating protrusions is configured to be brought into contact with an inner circumferential surface of the motor room.

Electric compressor with improved insulation performance

A motor-operated compressor includes a casing having an inner space in which a driving motor, an orbiting scroll and a fixed scroll are accommodated, and a controller provided outside the casing. The casing includes an intake hole formed at a side adjacent to the controller and an exhaust hole formed at a side adjacent to the fixed scroll on the basis of the driving motor. The casing includes a communication passage formed between the casing and a stator of the driving motor, such that a refrigerant introduced into the inner space through the intake hole is introduced into the suction chamber through the driving motor. A back pressure space supporting the orbiting scroll is sealed by oil. The stator has teeth on its inner circumferential surface and protrusions on its outer circumferential surface, each protrusion being located within a width range of each tooth.

Motor-operated compressor

A safety device for a vehicle can include an impulse sensor configured to sense an impact to the vehicle and generate an impulse signal based on the impact, a compressor configured to compress refrigerant for a refrigeration cycle of the vehicle, and a safety valve connected to the compressor and configured to receive the impulse signal from the impulse sensor, and in response to the impulse signal exceeding a predetermined value, open the safety valve to place an inner space of the compressor in communication with an outside of the compressor for discharging the refrigerant outside the vehicle.
