USE OF PERMANENT MAGNET TO ROTOR

Rotor with permanent magnet removes the loss of exciting current.

FULL DRIVEN BY SINE WAVE

Application of utility power ensures full sine-wave drive of "ECOSYNCHRO" motor. It is generally known that sine-wave is most efficient to drive motor with permanent magnet.

DRASTIC IMPROVEMENT IN COIL AREA EFFICIENCY

"ECOSYNCHRO" motor with dipole 2 slots or quadruple 4 slots allows simplification of coil section form into rectangle, resulting in improvement in Coil Area Efficiency.

TRAPEZODIAL OR SINE WAVEFORM MAGNETIZATION OF ROTOR MAGNET

This magnetization meets power generation waveform of the single motor with AC waveform of the power, resulting in realization of the minimized power loss.
