Does the maglev train have wheels?

In fact, maglev trains can be divided into normal guided maglev trains and superconducting maglev trains. The former has no wheels. The wheels of the maglev train are not hidden, but really have no wheels. It relies on its unique propulsion system to move forward. The principle of synchronous linear motor is used to drive the normally guided maglev train. The electromagnetic coil supported on the lower part of the vehicle and the three-phase moving magnetic field driving winding inside the ground track are equivalent to the excitation coil and the long stator winding of the synchronous linear motor respectively. According to the working principle of the motor, after the armature coil is electrified, it becomes a stator with electromagnetic induction, which can drive the rotor of the motor to rotate. Therefore, when the drive winding is energized, the train moves linearly under the action of electromagnetic induction. Therefore, in the suspended state, the train can completely achieve non-contact traction. Japanese superconducting maglev train has wheels. Although the superconducting elements used in this kind of train are completely conductive, when the train is just starting or braking, the speed is low, and the levitation force generated by the superconducting elements is not enough to overcome gravity and make the train "fly", so wheels are needed to provide support. Another function of superconducting maglev train wheels is to be used in emergency to ensure driving safety.
