Furthermore, the MG ECU calculates the rotational speed based on the amount of change in the position

within a given length of time.

• Because an alternating current flows from this resolver to the excitation coil at a constant frequency, a con-

stant frequency is output to the coils S and C, regardless of the rotor speed. The rotor is oval, and the dis-

tance of the gap between the stator and the rotor varies with the rotation of the rotor. Consequently, the peak

values of the waveforms output by the coils S and C vary in accordance with the position of the rotor.

• The MG ECU constantly monitors these peak values, and connects them to form a virtual waveform. The

MG ECU calculates the absolute position of the rotor from the difference between the values of the coils S

and C. It determines the rotor direction based on the difference between the phases of the virtual waveform

of the coil S and the virtual waveform of the coil C. Furthermore, the MG ECU calculates the rotational speed

based on the amount of change in the rotor position within a given length of time.

• The diagrams below illustrate the waveforms that are output at coils A, S, and C when the rotor makes a

positive rotation of 180

° from a certain position.
