<P>PROBLEM TO BE SOLVED: To provide a motor controller which can raise the reliability on the data transmission between a control part and a detection part by reducing the influence of the switching noise due to an inverter. <P>SOLUTION: The motor controller is equipped with the motor operation detection part 3 which detects at least either the rotational speed or the rotational position of an electric motor 2 and outputs detection information, and the control part 1 which controls at least either the rotational speed or the rotational position of the electric motor 2 by controlling a pulse width modulation system of inverter 89, based on the detection information outputted from the motor operation detection part 3. The motor operation detection part 3 has a timing detection means 25 which detects the switching timing of the inverter 89, and it is so constituted as to output the above detection information, synchronously with the switching timing detected by the timing detection means 25. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
