| Research Abstract |
The prototype of the 24 kw anti-directional-twin-rotary-motor was constructed. Due to the budget limitation, the elctrical vehicle (EV) simulator was constructed in stead of the converted vehicle. Using this EV simulator several driving conditions were tested, and for example the slipping of one rotor was suppressed by the proposed traction control. The low speed sensorless control was investigated, and 5 rpm was achieved. Also the secondary resistance estimation algorithm was proposed without injecting any signal to the primary current.
