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

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 a stator assembly for a motor. The stator assembly comprises a stator core having a plurality of teeth around each of which a stator coil is wound, a first insulator coupled to one side of the stator core to provide insulation between one tooth and an adjacent tooth, a second insulator coupled to the other side of the stator core to provide insulation between one tooth and an adjacent tooth, and a three-phase terminal inserted between the stator core and the second insulator and protruded partially to the outside of the second insulator to be electrically connected to an inverter. According to the present invention, there are advantageous effects that since the three-phase terminal is assembled between insulators, breakaway and breakage of the three-phase terminal can be prevented and that insulation effect and assembly capability thereof are enhanced.

Stator assembly for motor

A brushless motor includes a rotor in which permanent magnets are provided on an inner circumferential surface of a rotor core, and a stator in which teeth are provided on respective ends of stator cores around each of which a coil is wound. Each of the teeth is formed such that the distance between a facing surface which faces the permanent magnet and an inner circumferential surface of the permanent magnet is increased from the center of the tooth to the end thereof. Therefore, the rate of variation in magnetic resistance in response to variation in position of the rotor can be minimized, whereby cogging torque can be markedly reduced.

Brushless motor having a stator with teeth shaped to reduce cogging torque

An electric compressor includes a cover. The cover is reinforced by forming straight ribs, ring ribs, connection ribs, or hexagonal ribs having a honeycomb structure. The straight ribs, rings ribs, connection ribs, or hexagonal ribs are formed on the inner side or the outer side of a body of the cover on a side of an inverter.
