Abstract: 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.

Abstract: 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.

Abstract: 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.
