  • Description

    Tesla Columbus Egg Induction Motor Model Science Physics Experiment Technology Toys Educational Equipment High Tech Gizmo

    Product Name: Tesla Columbus Egg Induction Motor Model

    Product size: reference picture

    Product weight: 1.687kg

    Voltage: 220V

    Current: 200mA

    Power: 24W

    Product design

    In order to make the Columbus egg work, there must be two-phase alternating current and the phase difference is 90°, so we adopt the method of single-phase induction motor, that is, the capacitor voltage is used to lag the current by 90°, and we solve the problem of the Columbus egg work. power supply problem. A Columbus egg is an egg-shaped lump of copper. In a rotating magnetic field, the egg spins on its long axis, eventually standing due to the gyroscopic effect.

    Product technologies

    1. Customized silicon steel core

    2. 3D printed winding skeleton

    3. Transparent acrylic structure

    4. Fine winding set

    5. Equipped with 35mm solid copper ball

    Product use

    After receiving it, plug the power cord into the product, and flip the switch to turn it. It is not recommended to exceed 5 minutes each time, and the coil will heat up. It is recommended to cool down for a while before opening.

    Product Background Story

    At the Columbian Exposition in Chicago in 1893, inventor Nikola Tesla created the Columbus Egg to demonstrate the alternating current device he built, to demonstrate and explain the principles of the rotating magnetic field model and the asynchronous motor. Tesla’s device uses a toroidal core stator with four coil turns wound around it. The device is created by a two-phase alternating current source (such as a variable speed generator) to create a rotating magnetic field. The device operates at frequencies between 25 and 300 Hz. The ideal operating frequency is described as 35 to 40 Hz. Replicas for display purposes can be seen in the Nikola Tesla Museum in Belgrade, the Techno Museum in Zagreb and the Manual Museum in Ann Arbor, Michigan.

    Notice

    1. The product cannot change the power supply voltage and power without permission. It is strictly forbidden to arbitrarily connect the wires without permission.

    2. The product is made of acrylic, please do not expose it to the sun. Acrylic material is fragile in winter or when the temperature is relatively low, please use it carefully.

    3. It is strictly forbidden to touch the rotating motor with your hands, and the consequences are at your own risk.

    4. The pictures in the link are for reference only, and the actual product shall prevail.

    5. The product size is measured by hand, there is a certain error, please understand.
