Document Type and Number:
WIPO Patent Application WO/2020/246648
Kind Code:
A1
Abstract:
A drive motor of an electric vehicle having an inverter housing mounted therein according to the present invention is a drive motor of an electric vehicle which couples an inverter housing (20) to the top or side of a drive motor frame (11) so as to be changeable in position, through an inverter coupling bracket (30) between the drive motor frame (11) and the inverter housing (20). The inverter coupling bracket (30) includes an inverter housing surface-contacting frame (33) in which support gaps (31a, 32a) of first and second floor frames (31, 32), surface-contacting the circumferential surface of a flange (15) coupled to one end of the drive motor frame (11) and the circumferential surface of a bracket (18) coupled to the other end of the drive motor frame (11) in the longitudinal direction, are integrally formed. An arc-shaped drive motor frame circumferential surface-contacting portion (33a) is formed on the lower surface of the inverter housing surface-contacting frame (33). Fixing pieces (31b, 32b) inclined inward are formed at the left and right ends of the first and second floor frames (31, 32), respectively. A fixing protruding piece (33b) is formed at each of the front and rear ends of the inverter housing surface-contacting frame (33).
