Now just "Tiny Cooling Fan" market blowing "inverter" wind appeared false door, all walks of life for inverter fan industry GB missing rampant torture. Prior to this, false inverter event had ignited in the air conditioning industry has for many consumers wary, vendors access to some of the industry's core components in the circuit frequency of "high / low speed control module", in essence, just change the "Tiny Cooling Fan" to a motor winding voltage, thereby changing the motor operating voltage. However, the frequency of the alternating current motor at work has not changed, but also to say "Tiny Cooling Fan" function when there is no so-called frequency of operation, this is not consistent with the core feature inverter technology.
