摘要： A phase difference type resolver is adapted such that a calculator calculates an angle from a phase difference at a detection-signal zero cross point, determines a velocity at the angle based on an angle calculated from a phase difference at a previous detection-signal zero cross point, calculates an estimated angle at a next detection-signal zero cross point based on the velocity, divides a difference between the estimated angle and the angle into predetermined minimum detection angles, and outputs a real-time signal based on the minimum detection angles in a range after the angle but before the estimated angle.

摘要： For starting a three-phase four-pole sensorless brushless motor including a stator having three-phase coils and a four-pole magnet rotor provided in correspondence with the stator, it is arranged to energize any two-phase coils of the three-phase coils in a predetermined energizing sequence; monitor magnetic flux generated in the other one-phase coil; and switch the two-phase coils according to a specific case where the monitored magnetic flux changes to a positive or negative side and in mid-course further changes to an opposite side. For instance, when the specific case is a case where the magnetic flux monitored by first energization changes to the negative side and in mid-course further changes to the positive side, the first energization is immediately stopped and switched to fourth energization by skipping two energizations in the predetermined energizing sequence.
