Pulse signal generator, rotating machine, controller and power window controller

A magnetic path is formed by a magnetic detector (24) or (26) (more specifically, a magnetic wire (70)), the magnetic pole of a magnet (22), and a rotating shaft (20) as a motor rotates. Since the magnetic wire (70) consists of a magnetic body which may cause a great Barkhausen jump, the direction o...

Zusammenfassung:	A magnetic path is formed by a magnetic detector (24) or (26) (more specifically, a magnetic wire (70)), the magnetic pole of a magnet (22), and a rotating shaft (20) as a motor rotates. Since the magnetic wire (70) consists of a magnetic body which may cause a great Barkhausen jump, the direction of a magnetic field forming a magnetic path is switched steeply every time when the magnetic pole facing each magnetic detector is switched depending on rotation of the motor, and a pulse signal dependent on the switching is outputted from the magnetic detector. Since the direction of magnetization of the magnetic wire (70) is switched by variation in magnetic flux density received from the magnet (22), an induction electromotive force is generated by variation in magnetic flux received by a detection coil and a pulse signal can be outputted from the magnetic detector with no power supply.
