An inverter module according to an embodiment of the present invention comprises: a high voltage circuit unit which generates an inverter control voltage and a motor driving voltage by using a first DC voltage; a high voltage circuit pattern which electrically connects the high voltage circuit unit; a low voltage circuit unit which communicates with an external device by using a second DC voltage having a smaller magnitude than the first DC voltage; and a low voltage circuit pattern which electrically connects the low voltage circuit unit. The high voltage circuit pattern and the low voltage circuit pattern are spaced apart from each other.

Inverter module and electric compressor comprising same

The present disclosure relates to a high voltage cooling fan motor unit. For this purpose, the present disclosure includes a motorlocated inside a high voltage cooling fan motor housing; an inverter PCBlocated on the upper portion of the motor; a cover platefor covering the upper surface of the motor housing, assembled in the state of facing the inverter PCB, and having a groove partformed on the outside upper surface thereof; a cooling finprovided on the outside of the cover platein the state of facing the groove part; and a power conversion unitmounted on the lower surface of a heat sinkin the state of facing the inverter PCBvia the heat sinkmounted on the inside lower surface of the cover plate

High voltage cooling fan motor unit

BLDC motor including a stator with teeth which extend toward an inner side of a core and have a coil wound therearound; rotors disposed at an inner side of the stator and spaced apart from each other having a plurality of permanent magnets coupled to a core thereof; and hall sensors disposed and spaced apart to be opposite to an outer circumferential surface of the core of the rotor and disposed within a height range between both surfaces in a height direction of the core of the rotor to detect a change in a magnetic field in response to a rotation of the rotor, thereby accurately grasping positional information of a rotor and accurately controlling a rotation of the rotor by transmitting a magnetic flux generated from a permanent magnet of the rotor to a hall sensor enabling the hall sensor to detect a change in a magnetic field.

Brushless direct current motor

Disclosed herein is a motor-driven compressor with an inverter that is connected with an external power source via a connector part and controls a driving part which drives a compressing part to compress fluid. A printed circuit board is provided between the connector part and the driving part. Thus, noise transmitted from the driving part to the connector part is reduced, so that it is possible to minimize the transmission of the noise to an external power source.

Electric compressor

Disclosed herein is an electric compressor including: a main housing () having therein a suction chamber into which low-temperature refrigerant is drawn; an inverter housing () including an internal seating surface () formed adjacent to the suction chamber, with at least one inverter element () fixed at a surface thereof to the internal seating surface () while making contact with the internal seating surface (), the at least one inverter element () conducting heat to the main housing (); and at least one heat dissipation cover () disposed toward the main housing () while facing another surface of the inverter element () and enclosing the inverter element (), the at least one heat dissipation cover () having therein a receiving space () in which the inverter element () is received.
