| titleOfInvention | Motor-integrated magnetic bearing device |
| abstract | PROBLEM TO BE SOLVED: To provide a motor-integrated magnetic bearing device capable of reducing the heat generation of a motor rotor and improving the motor efficiency by making the current waveform of a motor coil close to a sine wave. The motor is a three-phase non-commutator motor having a phase detector for detecting the phase of the motor rotor. A calculation unit that generates a coil current application timing signal for applying a current to the coil 28ba of each phase of the motor stator 28b based on the output of the phase detector, and the motor stator 28b according to the coil current application timing signal output from the calculation unit. And a power circuit for applying a current to the coil 28ba of each phase. The calculation unit measures an interval at which the output state of the phase detector is switched, and generates 12 patterns of coil current application timing signals at an arbitrary angle for an electrical angle of 360 °. The 12 patterns of coil current application timing signals are signals of a pattern that alternately repeats 6-step 120 ° energization and 6-step 180 ° energization. [Selection] Figure 7 |
