  • Patent number: 10063173
    Abstract: A regulator, and vehicle alternator and rotating speed detection method thereof are provided. The vehicle alternator includes a rotor coil, a stator coil portion, a rectifier circuit and a regulator. The regulator is configured to control a current flowing through the rotor coil. The rotor coil collaborates with the stator coil portion to convert mechanical energy to alternating current (AC) electrical energy. The rectifier circuit converts the AC electrical energy provided by the stator coil portion to direct current (DC) electrical energy. When the vehicle alternator performs auto start operation by using residual magnetism, the regulator detects a frequency of a rotor voltage signal on the rotor coil to serve as a basis of calculating a rotating speed of the vehicle alternator.
