Title:
MOTOR UNIT AND DRIVING METHOD OF THE SAME
Document Type and Number:
Japanese Patent JP2020096489
Kind Code:
A
Abstract:
To reduce the number of detection elements and simplify wiring and control.SOLUTION: A first rotor 3 and a second rotor 203 are coupled by a coupling mechanism 300 so that mutual rotational phases do not shift. A first phase difference (angle δ) in the rotation direction of the first rotor 3 between a first magnetic sensor 10 and a second magnetic sensor 8 and a second phase difference (angle ε) between a magnetized waveform of the first rotor 3 and a magnetized waveform of the second rotor 203 is substantially equal.SELECTED DRAWING: Figure 14
