4. 180° energizing control
This is the control system to moderate the speed by the current phase difference for higher efficiency and lower noise of the compressor. The current
phase difference control is the control system paid attention to the interrelation between efficiency and phase gap generated by the applied voltage of
motor and current in the coil of motor as shown in the figure below.
This control is the forced magnetization system independent of the location of rotor, detecting the phase difference between driving voltage phase and
line current phase flowing in motor coil, and controls the modulation rate data to get the phase difference at the best efficiency.
