AC solenoids and DC solenoids issues

Rely on electromagnetic suction of two alternating magnetic field formed by superposition of a DC component of magnetic force to do work, and therefore inefficient, bulky core, coil and high energy consumption;
Low power factor, the coil current, severe fever, is a waste of energy and premature aging of the coil, damaged;
When the armature mechanical inlay cards, or overloaded, or low-voltage operation Dry Magnetic Separator with load difficulties, the coil will burn;
There frequency vibration noise. For the contactor, this vibration can lead to low voltage arcing contacts, contact burning, reduce product reliability and service life

;
Coil current, leading to bulky coils, causing the core bulky waste huge copper iron.
☆ ☆ ☆ DC solenoid

The whole process due to solenoid coil current is constant, so that more than 95% protection status of the energy is wasted energy is wasted for the heating coil, the coil hair

drum separator Hot and premature aging, damaged;
To reduce the heating coil, the coil wire diameter forced to increase, resulting in a huge waste of copper;
Coil volume increases, making the core volume increases, resulting in a huge waste of steel;
