DC brushless motor, new high efficiency and energy saving motor. Since 2008, from energy-saving lamps to energy-saving air conditioners to energy-saving vehicles, the Chinese government has adopted financial subsidies to guide industrial technology upgrades and seek low-carbon development countermeasures with a more active attitude and action. DC brushless motor products are also on the list, which has greatly improved the efficiency of conventional energy utilization.

The replacement of traditional motors with high-efficiency and energy-saving motors is the trend of the times, and the future space is huge. China’s motor power consumption accounts for 50% of total electricity consumption, accounting for nearly 70% of industrial electricity consumption. Therefore, to reduce the energy consumption per unit of GDP, there is much to be done in the field of electric motors, and high-efficiency and energy-saving motors can be used as a breakthrough in energy conservation.
DC brushless motors use semiconductor switching devices to achieve electronic commutation, and electronic switching devices replace traditional contact commutators and brushes. It has the advantages of high reliability, no commutation spark, and low mechanical noise.

DC brushless motor in the structural design, reasonable design of the stator and rotor magnetic density, to avoid saturation, high speed motor, properly reduce the magnetic density of each part
New high-efficiency energy-saving motor, DC brushless motor has the following breakthrough advantages

Efficient power saving. The new DC brushless motor has no iron loss and no magnetic damping, and the efficiency is greatly improved. Field test of industrial sawing machine shows that compared with the traditional system of traditional motor (brushed induction motor), the DC brushless motor can save 30% of electricity under working conditions. The actual application of the user proves that the 1.0 kW and 2 kW diesel power plants using this technology have a fuel saving rate of 40% compared with the conventional generator.
No brush, low interference. The DC brushless motor removes the brush. The most direct change is that there is no spark generated when the brush motor is running, which greatly reduces the interference of the spark to the remote control radio. Therefore, it is small in size and weighs only a fraction of the weight of a conventional motor. It can save 80% steel, 100% silicon steel, 50% copper.
High reliability. Long life and low maintenance costs

There is no brush. The wear of DC brushless motor is mainly on the bearing. From a mechanical point of view, the brushless motor is almost a maintenance-free motor. If necessary, only need to do some dust removal maintenance. The insulation performance is improved, waterproof, moisture-proof, dust-proof, reliable operation, low temperature rise, and improved environmental adaptability under extreme conditions. The traditional motor working time experiment is generally 2000 hours, while the DC brushless motor is up to 20,000 hours.

The Chinese government has always emphasized the use of high efficiency motors. To improve efficiency, it is to reduce various losses. The loss of the motor mainly includes iron loss, copper loss, mechanical loss and stray loss. The Fujitsu brand DC brushless motor is actively developing higher-quality motors, accelerating the replacement of brushless motors, and striving to achieve more energy-efficient and efficient motors.
