Since the 1970 s, with the development of power electronic technology, brushless dc motor speed regulation technology is mature, equipment increasingly lower prices, already applied. The specified format (brushless dc motorContinuous duty system, short-time duty system, intermittent cycle)Can bear and not cause motor controller overheating maximum output mechanical power is called its rated power, should pay attention to when using the provisions of the nameplate. Must be noticed when the motor running to make it match the load characteristics and the characteristics of the motor controller, avoid coasters or shut down. Electric function provides a large range of power, class from milliwatts to kilowatts. The use of the motor and control is very convenient and has since starting, acceleration, braking, reverse and stopper live ability, can meet various operation requirements; The work efficiency of the motor is higher, and without dust, smell, no pollution, noise is small. Because of its series of advantages, so in industrial and agricultural production, transportation, national defense, commercial and household appliances, medical electrical equipment and so on various aspects are widely used. General motor drive its output power will change with the rotational speed.
