Describe the nature of the rotating magnetic field and the principle of the three-phase induction motor.
The permanent magnet rotating magnetic field demonstrator consists of a bracket and a hoof-shaped permanent magnet with a fixed shaft. The blue side of the magnet is the S pole, and the red side is the N pole.
During use, pay attention to whether the connection between the coil and the terminal of the electromagnetic rotating demonstrator, and the connection between the terminal and the three-phase power supply is reliable.
