No hay artículos en el carro EUDAX - Linterna de dinamo para bricolaje, modelo educativo de construcción, modelo de enseñanza de actividad motora, manivela eléctrica, generador eléctrico de corriente continua, experimento de ciencia física, accionado a mano
Especificaciones:
Nombre del artículo: modelo de generador de manivela de bricolaje
Tamaño: 173 x 88 x 118 mm (largo x ancho x alto).
Material: plástico PVC y metal.
Color: Multicolor (blanco, rojo, amarillo, verde).
Modo de uso:
Cuando lo utilices, utiliza una correa para envolver la polea y hacer que el cepillo para polvo esté en buen contacto con el medio anillo de recogida. Girar la polea grande a través del balancín impulsa la armadura para girar. En este momento, un LED emite luz, cambiando la dirección de rotación y el otro LED emite luz. Se puede explicar que se genera una corriente en la bobina, y la energía mecánica se convierte en energía eléctrica.
Presta atención:
1. El cable y el anillo colector y el área de soldadura LED no deben tocarse a mano para evitar que la línea se desconecte.
2. Una vez completado el experimento, la funda del cinturón debe retirarse en una rueda para evitar que el cinturón se afloje y resbaladizo.
El paquete incluye:
1 juego de modelo de enseñanza de plástico (ya montado).
Advertencia: Peligro de asfixia. No apto para niños menores de 3 años.

Works ok but very cheap. Won't last long

The belt slips often and when turning counterclockwise the belt slips and it does not move the coil.

DC motor kit with rectangular coil assembly allows students to understand magnetism, forces and torques. The motor kit is marketed for its design as a generator. However, with just 6 volts DC on the brushes, the assembly acts as a DC motor. It is impressive to watch a cell phone video of the motor motion in slow motion! The assembly takes very little time as our shipped kit was preassembled and was ready to go. My student snipped the wire connections on the two LEDs for using the apparatus as a DC motor. You can always reconnect the LED wires to go back into the generator mode - if you wish to see red light or green light depending on the rotation direction of the crank.So, you can use this apparatus as a generator and watch the red or green diode light up - depending on the rotation direction of the rectangular coil. Or, as a DC motor - with a rectangular coil. Remember, the DC motor requires say, 6 volts ( using 4 of 1.5 volt AA batteries).After playing around with the generator, remove the durable rubber band from the hand crank with large pulley (which helps rotate the rectangular coil) . Then, connect the assembly to 4 AA batteries placed in series. Then watch the armature rotate! Do not forget to start the rectangular coil at an angle so that the two brushes individually touch the separate commutators. A small nudge of the coil is helpful to start the motor rotating - after connecting the battery in series to the brush connectors.Students will start to get the idea that the DC motor has an aspect that there is generator action going on here. This means that the generator emf goes against the current flowing in the magnetic rectangular coil. Therefore the spinning motor draws a smaller amount of current vs. the current that would flow if one blocked the rectangular coil from rotating. So students learn not to allow the motor to get stuck in one position, not rotate, and draw current that could damage the apparatus. This apparatus is alot of fun and a wonderful design to learn about motors and generators.

Works great in my electrical class to demonstrate generators and motors

As a physics teacher, I used it in a lab with very little difficulty. Occasionally, the magnet(s) would fall out (middle- and high-school students can be a bit rough) and it took a little trial-and-error to get them oriented correctly. Also, sometime the rubber band around the pulley would slip. But all-in-all, it's a good tool for experimenting with a DC generator.
