With the increasing development of science and technology, motor equipment has also become an important and indispensable position. Motor equipment and motor also need to be very careful in purchasing motor equipment. Motor in a machine is an important link affecting the life of a machine.So what is the principle of the motor equipment?
The working principle of the motor is based on the laws of electromagnetic induction, ohm's law of the whole circuit, and the laws of electromagnetic force.When the magnetic pole rotates clockwise, the magnetic line of the pole cuts the rotor guide bar, and the electromotive force is induced in the guide bar.The direction of the emf is determined by the right hand rule.Because the motion is relative, if the magnetic poles do not move and the rotor guide bar rotates counterclockwise, the electromotive force can also be induced in the guide bar.Under the action of electromotive force, a current is generated in the closed guide bar.This current interacts with the magnetic field of the rotating pole to subject the rotor guide bar to an electromagnetic force (ampere force), the direction of which can be determined by the left hand rule.The electromagnetic force, in turn, produces an electromagnetic torque, and the rotor turns.
