A plastic-package motor, including: a rotating shaft, a rotor assembly, a plastic-package stator, a front end cover, a rear end cover, an injection-molding end plate, and a conducting strip. The rotating shaft and the rotor assembly are installed and connected together. The plastic-package stator is sleeved outside the rotor assembly. The front end cover is injection-molded on the injection-molding end plate at the bottom of the plastic-package stator. The injection-molding end plate is covered outside the front end cover. The rear end cover is installed at the other end of the plastic-package stator, and two ends of the rotating shaft are supported on a bearing of the front end cover and a bearing of the rear end cover, respectively. One end of the conducting strip is electrically connected with the front end cover.
