Servo motor magnets you need to know the knowledge

Servo motor magnet in accordance with the different ways of receiving power can be divided into two major types of DC motors magnet and AC motor magnets, DC motor magnets in the power, the existence of self-induced electromotive force, will form a spark discharge, or school-pass circuit, the line Damage caused by other components of the towel. The use of AC motor magnets, due to the brake motor magnet delay release, resulting in failure of work, but the motor for the existence of residual magnetism, the stator winding induced potential dD in the AC electromagnet, so that the motor will not release the magnet 9. The solution is very simple, as long as the AC motor magnet coil L zero - an AC contactor normally open contact, so that the power to disconnect the motor magnet, while disconnecting the motor magnet and motor winding wire trapped. Let the motor magnet release immediately.
