Hand Start Crank AC/DC Generator Electromagnetics Scientific Physical Toy

Features:

.Mainly composed of stator, rotor, brush, rotating mechanism, base plate, etc.

.Demonstrate the working principle of the single-phase alternator: first, contact the two brushes with the copper ring and rotate the rotor (armature) to make the coil move in the magnetic field. If the coil is combined with the external circuit power generation board, it is a closed Circuit, the output of sinusoidal alternating current that changes periodically with time. If you connect a galvanometer in series with the Circuit and slowly rotate the armature, you can see that the magnitude and direction of the alternating current generated periodically change

.Demonstrate the working principle of a single-phase DC generator: During the demonstration, the two brushes and two half-copper rings should be contacted, respectively, and the armature is rotated. The copper half-ring rectifies the alternating current generated in the coil to obtain direct current. At this time, the red light is on, the green light is off, or the green light is on, and the red light is off. If you connect an ammeter in series with the Circuit, you can see the DC output at this time

.Suitable for children over 8 years old

.Technical Indicators:

1. When the rotor speed is 1200-1600/min, the output voltage of the machine, no-load current;

2. The voltage is not less than 6V, and the load voltage is not less than 3V, 0, 3A.

.Note:

1. When demonstrating, pay attention to the pressing of the brush and slip ring;

2. When the instrument is not in use, the "O" belt should be removed and stored, and at the same time, be careful not to come into contact with oil or sun exposure. To increase the service life of the belt, the proper lubrication of the bearing must always be paid attention to.
