Capacitor fixing structure for motor

The invention belongs to the technical field of motors, and particularly relates to a capacitor fixing structure for a motor. A capacitor fixing structure for a motor comprises a motor shell, a capacitor cover and a capacitor arranged in a cavity defined by the capacitor cover and the motor shell, the capacitor cover comprises a lateral shell, an upper bottom and a lower bottom, the upper bottom and the lower bottom are located at the two ends of the lateral shell, and an opening is formed in the side, facing the motor shell, of the lateral shell; the lower end of the capacitor is supported at the lower bottom of the capacitor cover, an annular elastic damping ring is arranged on the outer wall of the capacitor, the outer wall of the elastic damping ring abuts against the inner wall of a lateral shell of the capacitor cover and the outer wall of the motor shell, and inner convex bodies which are arranged oppositely at the same height are arranged on the inner wall of the lateral shell of the capacitor cover.
