CNC Electric Energy and no noise:

Traditional contactor closing is maintained by closing the electromagnetic coil is energized opening spring force to overcome to achieve, once the current smaller so that the Inverter Power Supply‍ electromagnetic force generated is insufficient to overcome the spring reaction force, the contactor can not keep closing state Therefore, the conventional AC contactor coil closing maintain that we must rely on electricity to maintain continuous, and this current from tens to thousands of milliamps. The permanent magnet AC contactor closing rely on the permanent magnetic force to maintain, without the need to generate an electromagnetic coil through the current closing force to keep only the electronic module 0.8mA-1.5mA operating current, thus, to maximize savings power, energy-saving rate of over 99.8%.

Traditional AC contactor coil is energized by closing maintain the electromagnetic force to make silicon, silicon pull so happened that when the grid voltage is low or uneven surface or movement silicon dust and foreign matter, there will be noise generation. The permanent magnet AC contactor closing to keep relying on the permanent magnetic force to maintain, so there will be no noise generation.

. ③ no temperature:

Rely on the conventional contactor coil is energized Electric transformer‍ to generate sufficient electromagnetic force to hold the pull coil is composed of a resistor and an inductor, a current is bound to the long-term heat, on the other hand, the magnetic flux passing through the core will produce heat, both heat contactor chamber together in often the contactor coil burned, while reducing the heat capacity of the main contacts. The permanent magnet permanent magnet AC contactor is to rely on force to maintain, without maintaining the coil, naturally there is no temperature rise.

. ④ contacts without chatter:

Retention of traditional AC contactor is energized by the coil to achieve, retention force with current, relevant magnetic gap, when the voltage fluctuations in the closing and opening a critical state, is in a similar close contact like sub-state, it will continue to tremor, causing contact welding or burning, leaving the motor burned out. The permanent magnet AC contactor retention, totally dependent on the permanent magnetic force to achieve a complete pull, voltage fluctuations will not affect the permanent magnetic force, either in the pull-state, or is in the open state, not in the middle of the state, Therefore, Circuit breaker‍ the possibility will not be the main contact chatter and burned, burned the motor is greatly reduced.
