Motor holder including radial and oblique connecting members

摘要

A motor holder for holding a motor (1) is provided. The motor holder includes a motor housing segment (11), a plurality of radial ribs (12a) and a venturi ring segment (13). The motor housing segment (11) receives and supports the motor (1). The radial ribs (12a) extend radially outwardly from an outer peripheral surface of the motor housing segment (11). The venturi ring segment (13) is connected to radially outer ends of the radial ribs (12a) and circumferentially surrounds the motor housing segment (11). The motor holder further includes a plurality of oblique ribs (12b). Each one of the oblique ribs (12b) is arranged between and is connected to each adjacent two radial ribs (12a). Furthermore, each one of the oblique ribs (12b) is oblique to a radial direction that extends from the motor housing segment (11).
