4 Samsung Electronics
The EHS(Eco Heating System) outdoor machine uses 10 Poles Rotor BLDC Motor. The Vibration is Lower than 8 Poles (Samsung
Conventionally Used) BLDC Motor . The Cogging Torque is Lower 54% compared to Conventional Motor.
2. General Overview
2-1 Features of the System
POWER SAVING
EHS(Eco Heating System) considers the trend in air conditioner use. It optimizes the
energy efficiency of loads ranging from partial to full. It achieves an excellent energy
effect for the users of the air conditioner.
Samsung patented compressor
Samsung has been researching and developing compressors since the 70's.
It has developed power saving compressors for more than thirty years.
The EHS(Eco Heating System) compressor adopts a double-rotor BLDC compressor with permanent magnets made by Samsung.
Electricity for the compressor rotor is obtained from a neodium-iron-boron permanent magnetic material (boron magnet can attract iron
material weighing 1000 times its own weight.) It strengthens the rotary moment of the compressor to maximize the entire efficiency of the
compressor.

SAMSUNG's double-rotor compressor has the upper and lower rotors designed symmetrically.
The double rotor in symmetry can remove vibrations caused by the eccentric design of the cylinder.
