Abstract
The utility model relates to a magnetic rotator of motive vehicle generators. A gear-shaped rotor body is installed on the generator shaft, the periphery of the gear-shaped rotor body is provided with notches with same interval and size, magnets are embedded in the notches, annular concave grooves are arranged at the two sides along the inner circle of the notches, magnetic iron rings are respectively inserted in the concave grooves at the two sides, and steel hoops are arranged on the external periphery edge of the rotor body and the magnets. The utility model has the advantages of simple structure, convenient assembly, low cost, high power, etc.
Description
The utility model motor generator magnet rotor, it relates to a kind of automobile-used generator that magnet rotor is arranged.
Generator amature on the current mobility car mostly is electric exciting generator rotor, and it is made up of the canine tooth utmost point palm, magnetizing coil, transmission of electricity slip ring and conduction carbon brush.Its shortcoming is that other parts are more, easy break-down, and the generator magnetizing coil must dispose storage battery, does not have storage battery, and generator does not generate electricity when beginning to start.
For overcoming the shortcoming that above-mentioned prior art exists, the utility model provides a kind of simple in structure, cost is low, power is high motor generator magnet rotor.
The purpose of this utility model is achieved in that installing gear-like rotor block on existing generator shaft, 8～12 notches of its periphery are rectangle or trapezoidal, be embedded rectangle or trapezoidal magnet in the notch with its coupling, has annular groove along circle both sides in the notch, installing magnetic conduction iron ring in the groove, rotor block and magnet circumferential periphery are provided with stirrup.
