## Abstract

An improved built-in capacitor motor structure includes a housing, a stator portion, an insulating member and a rotor portion. The housing includes a front cover and a rear cover for receiving the stator portion. The stator portion includes a core frame provided with an annular insulating frame body to which the insulating member connects. A plurality of circularly arranged docking units extend from the periphery of one side of the insulating frame body. A plurality of corresponding docking units are provided at the bottom side edge of the insulating member. These corresponding docking units are engaged with the docking units of the insulating frame body, respectively. The rotor portion is received in the stator portion. A capacitor is combined inside an accommodating space of the insulating member in communication with the outside, such that the capacitor is assembled inside the motor. In this way, assembly is easy while electromagnetic field of the motor is less easily affected.
