Because of the brushless dc motor can be directly use dc power supply, so widely used in unmanned car AGV, storage battery industry. Storage battery industry in the traction motor, instead of the traditional dc brush motor can achieve higher efficiency, higher activation torque features, such as by using square wave drive, allow time repair lead-acid battery electrode plates, can extend the life of the battery, increased by 1. Three times the battery capacity, can improve the comprehensive efficiency about double battery capacity, greatly improve the performance of the storage battery. Because of the brushless dc motor of the characteristics of high efficiency, low calorific value, very suitable for use in the 24 hours of continuous operation of industrial machinery and air conditioning refrigeration host, fan, water pump, air compressor load, etc. Time at low speed high torque and high frequent positive &negative not the characteristics of fever, more suitable for application in machine tools and machine tool of the traction motor drive; The steady speed running accuracy is higher than a dc motor, than vector control or direct torque control speed closed-loop variable frequency drive, better cost performance, is the best choice of the modernization and timing. Because of brushless dc miniaturization, can be used in high precision electronics industry for motor size requirements. As some medical machinery, semiconductor, such as measuring precision electronics industry for this type of motor of small size tend to have special favor.
