The invention relates to a driving motor left support and a suspension system, and belongs to the technical field of electric automobile suspension systems, the driving motor left support comprises a mounting plate, the mounting plate comprises a top plate and a side plate, and the top plate and the side plate are mutually connected to form an L-shaped structure; the reinforcing ribs comprise a first longitudinal rib, a second longitudinal rib and a third longitudinal rib which are vertically and fixedly connected to the side plates, and the tops of the first longitudinal rib, the second longitudinal rib and the third longitudinal rib are vertically and fixedly connected with the top plate; the connecting plate is parallel to the side plate, and the first longitudinal bar, the second longitudinal bar and the third longitudinal bar are fixedly connected with the connecting plate. According to the structure technology principle that an L-shaped beam, a T-shaped beam and a U-shaped beam have good mechanical performance and the like, an ingenious structural body design is adopted, especially the design requirement of the U-shaped beam at the connecting position of the driving motor left support and the motor assembly is met, the modal of the driving motor left support is improved to be larger than 700 Hz from 500 Hz, the design requirement is met, and the design cost is reduced. The lightweight design is achieved, and the part cost is reduced.
