High efficient Electric Motor
There is a group of researchers at the Tokai University, that invented a new brushless DC motor. This motor is up to to 96% efficient in converting electrical energy into usable form.
The motor is intended to be used in the eco-cars of the future, which have to be low emission along with being energy-efficient.
Another feature of the motor is that it can maintain the conversion efficiency in the range of 93% to 96% even if the output keeps on fluctuating from 50W to 200W.
However, the cost can be reduced to 1/4 or 1/5 if the production process is automated for mass production because the iron material itself is not expensive.
Setting aside the high cost, this motor has a wide range of applications, including refrigerators, electric bicycles and electric motorbikes, judging from its output and speed,
“(However,) the cost is nearly 20 times higher than that of commonly-used motors with efficiencies ranging from 80 to 89%,”
