Joint Lap DC Motor

Highly Efficient DC Scroll Compressor

DC Fan Motor

Highly Reliable Flat Fin

( M Series )

Our unique motor, known as “Poki-Poki Motor“ in Japan, employs joint lap production technique. Originally developed by Mitsubishi Electric, this motor offers high density and high magnetic force leading to high efficiency and high reliability.

By converting the motor’s electrical current waveform from the conventional waveform to a sine wave (180° con- ductance), this microprocessor raises the motor winding utilization ratio and reduces energy loss for higher efficiency.

( PUHZ Series )

The highly efficient scroll com- pressor is equipped with a “Frame Compliance Mechanism” that allows movement in the axial direction of the frame supporting the cradle scroll. This greatly reduces both leakage and friction loss, ensuring very high efficiency throughout the speed range.

Power Receiver and Twin LEV Control

( PUHZ Series )

Mitsubishi Electric has developed a power receiver and twin LEVs (linear expansion valves) that optimise the performance of the compressor. By ensuring optimum control in response to the operating waveform and outdoor temperature, this technology is tailored to the characteristics of the new refrigerant to enhance operating efficiency.

Thanks to the flat fin preventing clogging, the initial high energy efficiency is maintained throughout the unit's long lifespan.

PAM (Pulse Amplitude Modulation)

Electricity can be used efficiently with less loss, if the current wave resembles the supply voltage wave. PAM is a method for controlling the form of the current wave so that it conforms to the supply voltage wave. With PAM control, 98% of input power supply can be effectively used.
