| Abstract |
In this paper a new controller is proposed to operate the interior permanent magnet synchronous motor(IPMSM) by the control method of the maximum torque per ampere in constant torque region. The implementation method of the conventional torque controller is explained and analyzed exactly. The proposed controller does not use the torque and q-axis current of the speed controller but the amplitude of the stator current in order to utilize not only the magnetic alignment torque but also the reluctance in the constant region, gurantees the linearity of the torque, and is easily implemented. These attractive are verified through the experiment. |
