Operating principle of coreless motor
1.The motor rotates by virtue of the “electromagnetic force” on the coil.
2.Electromagnetic force: when an electric current passes through a coil in a magnetic field, the coil is forced by the magnetic field. This force is called electromagnetic force.
3.When the coil is fed a current in the direction of X, the coil is pushed upward according to Fleming’s left hand rule. At the same time, when the current direction is Y, the coil will be pushed down. The two forces interact to balance the motor and make it spin.
Vibration principle of vibration motor
When the motor rotates, the counter weight rotates with the rotor, generating centrifugal force.
