The invention relates to a wheel hub motor testing device and a testing method thereof, and the device comprises a pedestal which is provided with a dynamometer, the dynamometer is provided with a rotating shaft in an extending manner, and the rotating shaft is used for connecting a rotor end of a wheel hub motor assembly; the supporting frame is installed on the base, an installation hole is formed in the supporting frame, the installation hole and the rotating shaft are coaxial, and the installation hole is used for fixing the stator end of the hub motor assembly; and the loading device is used for loading the hub motor assembly, one end of the loading device is mounted on the base, and the other end of the loading device can move along the radial direction of the mounting hole. And the hub motor assembly can be tested independently, and a whole vehicle bench test is not needed, so that the test cost is greatly reduced. And ground supporting force and friction force borne by the hub motor assembly in the ac
