Abstract
The utility model provides a double-motor two-dimension integrated three-phase asynchronous hub motor and a variable-frequency drive control system, wherein, the hub motor is composed of two three-phase asynchronous variable-frequency motors. The hub motor adopts two integration methods: the first method is that the two motors are respectively arranged on the left and the right sides of the rear wheel of a two-wheel electric vehicle; and the second method is that the two motors are respectively arranged on the front and the rear wheels of the two-wheel electric vehicle. Moreover, the hub motor can operate in three different ways, and has the advantages of excellent working environment adaptability and energy-saving effect. The hub motor is further combined with a variable-frequency drive controller to form a novel electric drive system for the two-wheel electric vehicle, which has the advantages of variable-frequency energy saving, regenerative braking energy saving, and substitution of motor plugging for mechanical friction braking, etc.
