<P>PROBLEM TO BE SOLVED: To provide a motor controller and a method therefor capable of reducing a cost using conventional circuits and components and of additionally performing accurate current control in a wide range of at least 10 times as large as a conventional type. <P>SOLUTION: This motor controller includes a torque/current converter 10 for comparing a predetermined set torque command switching value T<SB>0</SB>with an absolute value ¾T*¾ of a torque command T* to determine that the torque command T* is a high torque area or a low torque area and to output the current command corresponding to a torque determination result, and a speed area determination device 50 and a torque control angle calculator 60 in which the torque command T* operates only in a low torque area based on the torque determination result. <P>COPYRIGHT: (C)2007,JPO&INPIT |
