Description
Technical field
The utility model relates to teaching aid, relates in particular to a kind of direct current generator apparatus for demonstrating.
Background technology
Export or be input as the electric rotating machine of direct current energy, be called direct current generator, it is to realize the mutually motor of conversion of direct current energy and mechanical energy.When it does the motor operation, be direct current motor, convert electrical energy into mechanical energy.Direct current generator the inside is fixed with the annular permanent-magnet body, electric current produces Ampère force by epitrochanterian coil, when epitrochanterian coil is parallel with magnetic field, continuing to turn the magnetic direction that is subject to will change again, therefore the brush of Rotor terminal alternately contacts with conversion sheet at this moment, thereby the direction of current on the coil also changes, and the Lorentz force direction of generation is constant, so motor can keep a direction to rotate.In education activities, for the ultimate principle of direct current generator displays to the student intuitively, be necessary to design a kind of direct current generator apparatus for demonstrating, this apparatus for demonstrating need to have simple in structure, the characteristics such as the easy dismounting of each parts.
The utility model content
The purpose of this utility model provides a kind of direct current generator apparatus for demonstrating.
The utility model is that the technical scheme that its technical matters of solution adopts is,
The direct current generator apparatus for demonstrating, include fixing base, be provided with direct supply in this fixing base, the fixing base two ends have conductor support, this conductor support links to each other with the electrode of direct supply respectively, conductor support is provided with coil, the coil two ends have the conductor rotating shaft, and this conductor rotating shaft is communicated with the coil two ends respectively, and coil is located on the conductor support by this conductor rotating shaft, and can rotate in conductor support, also be provided with permanent magnet on the fixing base, the magnetic pole of this permanent magnet points to coil, and wherein a conductor rotating shaft surface coverage has insulation course, this insulation course occupies half of this conductor shaft circumference face, another root conductor rotating shaft and conductor support conducting.
The utility model has the advantage of that this device makes up the necessary parts of the direct current generators such as coil, direct supply and permanent magnet by simple and clear mode, make the student be more readily understood principle and the course of work of direct current generator.
Description of drawings
