Abstract
An electric-controlled idler-type supercharger mainly includes a free rotor, an electric rotor, and an electric control gear mounted inside a turbine casing. The electric rotor includes an electromagnet screwed to a transmission shaft of the electric rotor, and the free rotor is rotatably mounted to an end of the transmission shaft with a permanent magnet thereof corresponding to the electromagnet. A conductive coil is wound around the electromagnet with two coil leads connected to two collector rings of the electric control gear. The collector rings are then connected to a power switch via two carbon brushes, two expansion springs and two conductive terminals. By turning the power switch on or off, it is possible to control working characteristics of the supercharger.
Claims4
An electric-controlled idler-type supercharger, comprising:
- a turbine casing;
- a free rotor having a main body constituting a turbine, said turbine being internally provided at a predetermined position with a permanent magnet;
- an electric rotor including an electromagnet screwed to a transmission shaft of said electric rotor and a conductive coil wound around said electromagnet;
- and
- an electric control gear including two collector rings mounted around said transmission shaft, two carbon brushes separately connected to said two collector rings, two expansion springs having an end connected to said two carbon brushes and another end connected to two conductive terminals;
- said free rotor being rotatably mounted around an end of said transmission shaft, such that said permanent magnet of said free rotor is at a position corresponding to said electromagnet of said electric rotor;
- said conductive coil having two coil leads separately connected to said two collector rings of the electric control gear;
- and
- said free rotor, said electric rotor, and said electric control gear all being mounted in said turbine casing.
