| 发明名称 | Angle detection method with resolver | ||
| 摘要 | In an angle detection method with a resolver, the method being for detecting a rotational angle of a rotator by synchronously detecting a first signal and a second signal that are two phase sine wave modulation signals obtained from a one phase excitation/two phase output resolver, the method includes: a first signal detection process which detects a signal in the order of the first signal and the second signal; and a second signal detection process which detects a signal in the order of the second signal and the first signal. | ||

| 主权项 | 1. An angle detection method with a resolver, said method comprising detecting a rotational angle of a rotator by synchronously detecting a first signal and a second signal that are two phase sine wave modulation signals obtained from a one phase excitation/two phase output resolver, said method further comprising: a first signal detection process which detects a signal in the order of the first signal and the second signal; a second signal detection process which, after a predetermined time has elapsed after completion of the first signal detection process, detects a signal in the order of the second signal and the first signal; and calculating a rotational angle of the resolver using signals detected by the first signal detection process and the second signal detection process. | ||
