Neo Magnets Raise the Efficiency of Electric Mo Neo Magnets Raise the Efficiency of Electric Motors

The growing number of electro-mechanical devices employed in today's automobiles places an increasingly severe load on the alternator. For this reason, car manufacturers are seeking to increase device efficiencies, thereby reducing the current drawn from the alternator. An added benefit of using higher-efficiency motors and actuators is an improvement in fuel economy. Car manufacturers estimate the improvement in fuel efficiency attributed to electric current drain to be about 0.024 litres/100 km per amp. Of all the motors employed in today’s automobile, the engine cooling fan (ECF) blower motor has the greatest fullduty power consumption, drawing over 20 amps at 12 volts.
