Problems solved by technology

[0005] That is, since the existing BLDC motor built in an inverter uses a plurality of sealing rubbers for water-sealing between the inverter unit 20 and the connector block 30 and between the connector block 30 and the electric wires, Therefore, the package structure of the connector block including the connector block, sealing rubber, etc. is complicated, so that the process of producing and assembling the parts will be complicated and the manufacturing cost will be increased.

Abstract

Provided is an inverter built-in brushless direct current (BLDC) motor, in which an inverter housing and a cover are coupled to each other by having a connector block interposed therebetween, a sealing portion formed in the connector block seals between a circumference in a height direction and a length direction of the connector block and an inner side surface of the inverter housing and the cover, and a space between an electric wire penetrating through an electric wire through hole and the connector block, thereby simplifying parts for forming a watertight structure, easily sealing between the inverter unit and the connector block and sealing between the connector block and the electric wire, and reducing a package size including a connector block assembling part formed in the inverter unit and the connector block.

Description

technical field [0001] The following disclosure relates to an inverter built-in brushless direct current (BLDC) motor, and more particularly, to an inverter built-in BLDC motor capable of forming a watertight The part for forming the watertight structure is simplified by using the permanent connector block, and it is possible to easily perform sealing between the inverter unit and the connector block and between the connector block and the electric wires. Background technique [0002] Brushless DC (BLDC) motors prevent friction and wear (a drawback of existing DC motors) and are relatively efficient. Therefore, recently, a hybrid vehicle tends to adopt a BLDC motor as a motor for rotating a cooling fan. [0003] A BLDC motor is a motor that does not have the brushes and commutator necessary for a DC motor but has an electronic commutation mechanism installed in it. [0004] Furthermore, an existing BLDC motor assembly for a low-voltage cooling fan of a vehicle has a motor ...
