Abstract
The utility model discloses a single-turn coil generator principle demonstrator, comprising a base plate (1), an opposite magnetic pole type permanent magnet (2) disposed on the base plate (1), a rectangular coil (3) disposed between the permanent magnet (2), and a bracing rod (4) disposed in the middle of the rectangular coil (3). One end of the bracing rod (4) is provided with a round hole through which the rectangular coil (3) can pass, and the other end of the bracing rod (4) is provided with a contact (5). The contact (5) separates two contacts of the rectangular coil (3) and cooperates with an internal and external brush. The internal and external brush is connected in series with a current indicator (6) through a wire. The contact (5) is provided with a commutator. The base plate is provided with a sliding block fixture. The permanent magnet is clamped in the fixture. Beneficial effects of the demonstrator are reasonable structural design, stable operation, convenient operation, good demonstration effect, and the demonstrator is firm and reliable.
Description
Technical field
The utility model relates to instruments used for education, is specifically related to a kind of single-turn circular coil generator principle demonstration device.
Background technology
Single-turn circular coil generator principle demonstration device has become the teaching aid of school's indispensability.Traditional single-turn circular coil generator principle demonstration device structural design is simple, because coil does not often arrange support bar, not steady during rotation, causes distortion, thereby interfere because rocking, and has affected the normal use of instrument.In addition, owing to not being equipped with commutator, can only change direction of current by rotating backward coil, operate very inconvenient.
Summary of the invention
For the shortcoming of existing single-turn circular coil generator principle demonstration device, the utility model provides a kind of novel single-turn circular coil generator principle demonstration device.
To achieve these goals, the measure that the utility model is taked:
A kind of single-turn circular coil generator principle demonstration device, comprise base plate, base plate is provided with magnetic pole type permanent magnet, in the middle of permanent magnet, be provided with square coil, square coil middle part is provided with support bar, support bar one end is provided with the circular hole that allows square coil to pass, the support bar other end is provided with contact, contact is isolated two joints of square coil match with interior outer bruss, interior outer bruss is connected with electric current demonstration meter by wire, contact is equipped with commutator, and base plate is provided with slide block type fixture, and permanent magnet is clipped in fixture.
The voltage of electric current demonstration meter direct supply used is 1.2 to 1.5 volts.
Electric current demonstration meter is electrically connected to LCDs, and the parameter of electric current demonstration meter shows by LCDs.
The beneficial effects of the utility model: reasonable in design, solid and reliable, operate steadily, easy to operate, good demonstration effect.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model.
Embodiment
A kind of single-turn circular coil generator principle demonstration device, comprise base plate 1, base plate 1 is provided with magnetic pole type permanent magnet 2, in the middle of permanent magnet 2, be provided with square coil 3, square coil 3 middle parts are provided with support bar 4, support bar 4 one end are provided with the circular hole that allows square coil 3 to pass, support bar 4 other ends are provided with contact 5, contact 5 is isolated two joints of square coil 3 match with interior outer bruss, interior outer bruss is connected with electric current demonstration meter 6 by wire, contact 5 also can be equipped with commutator, and the voltage of electric current demonstration meter 6 direct supplys used is 1.2 to 1.5 volts.Base plate 1 is provided with slide block type fixture, and permanent magnet 2 is clipped in fixture, can clamp by slide block type fixture the permanent magnet of different length.
The beneficial effects of the utility model: reasonable in design, solid and reliable, operate steadily, easy to operate, good demonstration effect.
Those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
