Description

Uses: Explain the nature of the rotating magnetic field and the principle of a induction motor.

Structure:
The permanent magnet rotating magnetic field consists of a bracket and a hoof-shaped permanent magnet with a fixed shaft.
The electromagnetic field rotation consists of three equally spaced square coils. The three coils are respectively wrapped with red, yellow and blue ribbons to show the difference. There are three terminals on the base for external power supply.
Bearings are mounted on the magnetic needle, aluminum frame, plastic frame and squirrel cage rotor. When they are mounted on the needle holder, they can be rotated flexibly.

Precautions
In use, it is necessary to pay attention to the electromagnetic rotation coil and the binding post, whether the connection between the terminal and the power supply is reliable.
The electromagnetic rotation coil should be prevented from being deformed, misaligned, and prevented from being damaged by permanent magnets.
