ANGLE DETECTING MODULE AND METHOD FOR MOTOR ROTOR |
| 摘要 |
An angle detecting module for a motor rotor is provided. The angle detecting module includes a permanent-magnet synchronous motor, three linear hail components and a processing device. The permanent-magnet synchronous motor includes a stator and a rotor. The three linear hall components are disposed on the stator; and the linear hall components are spaced by electrical 120 degrees. Each of the linear hall components outputs an analog signal after measuring a magnetic field, position of the rotor, and each of the analog signals has magnetically saturated third harmonic component. The processing device is electrically connected to the linear hall components, and the processing device optimizes each of the analog signals and generates an average rotor angle. |
